Abstract

Pituicytoma is a tumor extremely rare in childhood, with only 4 cases reported in literature. It is thought to arise from the specialized glial elements called “pituicytes.” The association of pituicytoma and Cushing’s disease (CD) has been described only once so far, in an adult patient.

A 7-year-old girl was referred for clinical signs of hypercortisolism, and a diagnosis of CD was made. MRI revealed 2 pathologic areas in the pituitary gland. The patient underwent surgery, with microscopic transsphenoidal approach, and a well-circumscribed area of pathologic tissue was identified and removed. Surprisingly, histologic and immunohistochemical study provided unequivocal evidence of pituicytoma. No pituitary adenoma could be identified.

For persistent hypercortisolism, the patient necessitated transsphenoidal endoscopic reintervention and 2 other lesions were removed. By immunohistological examination, these lesions were confirmed to be corticotropin-secreting adenoma. Unfortunately, there was no postoperative decrease in corticotropin and cortisol levels, and the patient underwent bilateral laparoscopic adrenalectomy.

Considering that we report a second case of association of pituicytoma and corticotropin-secreting adenoma, that CD is infrequent, and pituicytoma is extremely rare in childhood, the coexistence of these 2 tumors should not be considered a mere coincidence. To date, there is no conclusive evidence about the origin of these different subtypes of pituitary tumors. This case supports the hypothesis that these tumors share a common progenitor cell, which could be the folliculostellate cell.

Well it has taken me a year to write this bio…and just to give some hope to those of you just going thru this process…I have to say that after surgery I have not felt better! I am back to who i always knew I was….the depression and anxiety is gone and I am living life like a 24 year old should!

I guess it all started when i was sixteen (hindsight is 20-20 i guess). My periods stopped i was tired all the time and the depression started. We all kind of just chalked it up to being sixteen. But my mom insisted something was not right. we talked with my gyno…who said nothing was wrong, I had a fungus on my head (my hair was getting really thin) and sometimes girls who had normal periods (in my case three years of normal periods) just go awry.

My mom wasnt hearing that and demanded a script for an endo. I went….he did blood work…and metioned cushings. But nothing came back definitive…so they put me on birthcontol and gave me some hormones and the chushings was never mentioned again because that all seemed to work.

As time went on my depression got worse, the shape of my body started to change-my face and stomach was the most noticeable- and my energy level kept going down. I kept going back to the doctors asking to be tested for mono..or something. I went to a psycologist….but i knew there was no reason for my depression. Two of them told me “i had very good insight” and that I didnt need them. I started getting more anxiety..especially about going out socially.

High school ended and my typical optimistic personality started to decline. I put on a good act to my friends but my family was seeing me break down all the time. I went away for college (all the while gaining weight). My sophmore year I had a break down..I called my family crying that i needed help. I couldnt beat my depression. I didnt drink in college because i knew that would mean instant weight gain, i barely went out…i exercised everyday..hard….i joined weight watchers…i stuck with it. I was at 103 lbs….that crept up to 110…that crept up to 117…each time my weight goal would be “ohh if i could just get back to 108..112…115” with each weight gain my original weight goal would get higher and higher.

Internally i felt like I was constantly under a black cloud..i knew there was no reason why i shoudl feel this way..i was doing great in school, i had a supportive family, an amazing boyfriend and great friends…why was i depressed? I was becoming emotionally draining to the people closest to me…I would go home a lot on the weekends…i was diagnosed with PMDS….like severe PMS..and was given an antidepresant…i hated it it made me feel like a zombie…i stopped taking it and just made it apoint to work on fighting the depression….and the weight gain.

When i was done college i was about 120 lbs. My face was getting rounder and rounder..i was noticing more hair on my face and arms…and a hump between my shoulder blades and the bottom of my neck. My mom saw a tv show about Polycystic ovarian syndrome and felt that maybe that was what was going on with me…i went to my PCP with this and she said it was possible and that i should to talk to my gyno….I am 4’8 and at the time weighing close to 125..i talked to my gyno and she said I was not heavy..that i was just “itailan” ..i told her my periods were getting abnormal again even w/the birthcontrol and that i was so tired all the time and my arms and legs ached. I also told her that i was bruising very easily…and that the weight gain would not stop despite my exercising and following the atikins diet very strickly for over 6 weeks. My boyfriend and I decided to try the diet together..he lost 35 llbs in 6 weeks..i lost NOTHING! I went back to my PCP who ordered an ultra sound of my ovaries…..NOTHING.(i kept thinking i was going crazy and that it was all in my head)….she also decided to do some blood work…and as i was walking out the door she said..”you know what..i am going to give you this 24hr urine test too. Just so that we cover everything”. I just kept thinking please let something come back ….please dont let this be all my fault…please dont let this be all in my head…..please dont let me be crazy. When i got the test results back it turned out that the 24hr urine test was the one test i needed to get on the right track to finding what was wrong. My cortisol level was 3x’s the normal.

I went to an endo…by the time i got to the endocronoligist i was up to 130…i could not work a full day without needing a full day of sleep and my body was aching beyond description. I was crying all the time…in my room…and was becoming more and more of a recluse…i would only hang out with my boyfriend in our houses. I looked my symptoms up on the internet and saw cushings…that was it! I went to the endo and told him..i think it is cushings….he said he had only saw it one other time and that he wanted to do more tests. I got CAT scans, x-rays, MRI’s….my adrenals my pituitary my lungs….he did a CRH stimulation test which was getting blood work done every fifteen minutes for 90minutes….it took weeks to get that test scheduled..no one had ever heard of it and therefore did not know how to do it…..finally after 3 months of tests my dr. felt he had enough evidence to diagnos me with cushings disease (tumor on my pituitary) I was diagnosed in March of 2004. By this time i was about 137 lbs i had to work part time (i am an occupational therapist for children..i do home visits….i could not make it thru a whole day)

In April i had to change to office work…i could not lift the children and i could barely get up off the floor. I have to say i was one of the lucky people who worked for people who were very supportive and accomidating…my boss was very willing to work with me and willing to hold my job for me.

July 30th 2004 i finally had transphenodial surgery to remove my tumor (they went thru my lip and nose because they felt my nose was too small). It is now over 1 year later….i am down to 108 lbs, i have so much energy…no depression….and i dont mind looking at myself in the mirror…i am enjoying my friends and my boyfriend…(who stayed with me thru it all) And my family. I feel healthy mentally, emptionally, and physically. And i just got back into my size 2 jeans!!!

It was a crappy time…(as i am sure you all can atest to) but i learned a lot…..most importantly i was bombarded by good wishes and prayers….friends requested masses for me…a nun in brazil prayed for me…people who i never thought i touched their lives…took the time to wish me well…send an email..or call….I got to experience the wonderful loving nature of human beings and i was lucky to be supported by my family (my mom, dad, and two younger brothers) and my boyfriend throughout this entire tough journey.

This experience taught me to realize the strength i have as well as to appreciate the good and the bad in life. I was on hydrocortizone for about 8 months…i was lucky that my tumor was in its own little sack so my pituitary gland was not touched. In the end in took about 7 years to diagnose me..i think that if the dr. at 16 would have pursued the cushings idea nothing would have been found because it took so long for my symptoms to really peak…needless to say i love my PCP and my endo ..and that i changed gyno’s…

I just want to let anyone out there going thru this disease to know..you are not alone….and to take each day is stride…when you need help ask for it….and that this road can lead to a happy ending. God Bless!

ps- it is ok to feel bad about what you are going thru…it is a tough thing to endure…and when the docotors tell you there is noting wrong…..follow your gut…and you keep searching for the doctor that will listen… If there is anyone in the philadelphis of south jersey area who needs someone to talk to please feel free to email me…fapadula@hotmail.com…i will help you out the best i can!

Update November 6, 2011

Well- here is an update, after seven years of being Cushings free it has returned.

With in those seven years I married my college boyfriend and we now have a son- Nicholas who will be 2 in Decemeber. It has been a blessed and wonderful seven years. However right around when my son was turning 1 I started to notice symptoms again. Increase facial hair, the whole “roundness” of my body, buffalo hump. I decided I was going to work out hard, eat right, and see – I didnt just want to jump to any conclusions. I stuck to it- and nothing…..my hair started thinning again and the acne was coming back and then the missed periods…..so I went to my PCP- told them i needed the 24hr urine and wouldnt you know…..427 cortisol level (on that 0-50 scale)……here we go again.

So back to endo- now at Penn Pituitary Center…..it was another journey b/c the tumor wasnt definative on MRI, and it seems to be cycling…..but I was diagnosed with Cushings again- with the option of 2nd pit surgery or BLA…….after some months of trying to make a decision I went with the 50/50 chance of the second pituitary surgery on 10/26/2011.

It didnt work- my levels never came down in the hospital and I went home w/ out of range cortisol levels and no need for medication……BLURG……Sooooo on to the next step…..after I recover from this surgery I will most likely have the BLA- with the hopes of not having to deal with Cushings ever again. This time around has been a little more difficult just with being a mom and feeling sick- but I still continue to be amazingly blessed with a supportive family and husband and we are surrounded by love and support and for that I am beyond greatful.

I keep all of you in my prayers for relief and health- as I ( we all) know this no easy journey.

Many Blessings!

Fabiana

Update September 12, 2015

So to bring this up to date. My second pituitary surgery in 2011 was unsuccessful. January of 2012 I had both of my adrenal glands removed. Going to adrenal insufficiency was a very difficult transition for me. It took me nearly 2 years before I felt functional. As time went on I felt more human, but I haven’t felt healthy since that day. I can and do function, but at a lower expectation of what I used to be capable of….my “new normal”.

My husband and I decided to try for a second child…my pituitary was damaged from the second surgery and we needed fertility…after 8 months of fertility I got pregnant and we had our second son January of 2015.

In April of 2015 we discovered that my ACTH was increasing exponentially. MRI revealed a macroadenoma invading my cavernous sinus. The tumor is sitting on my carotid artery and milimeterrs away from my optic chasim. I was not a candidate for another surgery due to the tumors proximity to.both of those vital structures.

So September 1st of this year I started daily radiation treatments. I spent my 34th birthday getting my brain zapped. I am receiving proton beam therapy at the Hospital of the University of Pennsylvania. I am so lucky to live so close to an institute that has some of the rarest treatment options.

Again Cushing’s is disrupting our life, my husband goes with me every night to radiation while family takes turns watching the kids….I am now on my 18th year of fighting this disease. I never imagined it would get to this point.

But here we all are making the best of each day, fighting each day and trying to keep things as “normal” as possible. Blessings to all of you fighting this disease…my new go to saying is” ‘effing Cushing’s”! For you newbies…Fight, Advocate for yourselves, and find a doc who doesn’t dismiss you and hang on to them for dear life.

BLA Instead of Second Pituitary Surgery

One of the problems that can arise with a BLA (bilateral adrenalectomy) instead of a repeat pituitary surgery for Cushing’s recurrence is Adrenal Insufficiency.  Another is Nelson’s Syndrome.

Nelson’s syndrome is a rare disorder that occurs in some patients with Cushing’s disease patients as a result of removing both adrenal glands. In Nelson’s syndrome, the pituitary tumor continues to grow and release the hormone ACTH.

This invasive tumor enlarges, often causing visual loss, pituitary failure and headaches. One key characteristic of Nelson’s disease is dark skin pigmentation, resulting from the skin pigment cells responding to the release of ACTH.


AnchorNelson’s Syndrome: Physiology

Nelson’s syndrome can develop as a result of a specific treatment (bilateral adrenalecomy) for the pituitary disease called Cushing’s disease. The harmful effects of Cushing’s disease are due to the excessive amount of the hormone cortisol produced by the adrenal glands.

To treat Cushing’s disease, your doctor may recommend removing the adrenal glands, during a procedure called a bilateral adrenalectomy. The procedure will stop cortisol production and provide relief. However, the procedure does not treat the actual tumor. Rapid growth of the pituitary tumor can occur.

In about 15-25 percent of patients who had a bilateral adrenalectomy, Nelson’ syndrome develops within one to four years.


Darkening of Skin Color - Nelson's Syndrome SymptomAnchor

Nelson’s Syndrome: Symptoms

The most obvious symptom of Nelson’s syndrome is the darkening of the skin color (hyperpigmentation).

Macroadenomas

Macroadenomas are large pituitary tumors. Large tumors can compress surrounding structures, primarily the normal pituitary gland and optic (visual) pathways, causing symptoms. The symptoms that result from the compression are independent of the effects of excess growth hormone secretion.
This may result in vision problems:

  • Vision loss. This occurs when macroadenomas grow upward into the brain cavity, compressing the optic chiasm.
  • A loss of the outer peripheral vision, called a bitemporal hemianopsia Bitemporal Hemianopsia - Symptom of Nelson's Syndrome
    • When severe, a patient can only see what is directly in front of them.
    • Many patients do not become aware of their visual loss until it is quite severe.
  • Other visual problems can include:
    • Loss of visual acuity (blurry vision), especially if the macroadenoma grows forward and compresses an optic nerve.
    • Colors not perceived as bright as usual

Pituitary Failure or Hypopituitarism

Increased compression of the normal gland can cause hormone insufficiency, called hypopituitarism. The symptoms depend upon which hormone is involved.


AnchorNelson’s Syndrome: Diagnosis

Most patients with Nelson’s syndrome have undergone a bilateral adrenalectomy for the treatment of Cushing’s disease

Diagnostic testing includes:

  • Hormone testing. Typically, the blood ACTH levels are very elevated. Learn more about hormone testing at the UCLA Pituitary Tumor Program.
  • MRI imaging. Magnetic resonance imaging (MRI) scan of the pituitary gland can detect the presence of an adenoma, a pituitary tumor.

AnchorNelson’s Syndrome: Treatment Options

Surgery for Nelson's Syndrome

Treating Nelson’s syndrome effectively requires an experienced team of experts. Specialists at the UCLA’s Pituitary Tumor Program have years of experience managing the complex coordination and care for treatment of Nelsons’ syndrome.

Treatment options include:

AnchorSurgery for Nelson’s Syndrome

Surgical removal of the pituitary adenoma is the ideal treatment; however, it is not always possible. Surgical removal requires advanced surgical approaches, including delicate procedures involving the cavernous sinus.

If surgery is required, typically the best procedure is through a nasal approach. Our neurosurgeons who specialize in pituitary tumor surgery are experts in the minimally invasive expanded endoscopic endonasal technique. This procedure removes the tumor while minimizing complications, hospital time and discomfort. This advanced technique requires specialized training and equipment.

Very large tumors that extend into the brain cavity may require opening the skull (craniotomy) to access the tumor. Our surgeons are also experts in the minimally invasive “key-hole” craniotomy, utilizing a small incision hidden in the eyebrow.

AnchorRadiation Therapy for Nelson’s Syndrome

Radiation Therapy for Nelson's SyndromeRadiation therapy can be effective in controlling the growth of the tumor. However, if you received radiation therapy in the past, additional radiation may not be safe.

Our Pituitary Tumor Program offers the latest in radiation therapy, including stereotactic radiosurgery. This approach delivers a highly focused dose of radiation to the tumor while leaving the surrounding brain structures unharmed (with the exception of the normal pituitary gland).

One consequence of radiation treatment is that it can cause delayed pituitary failure. This typically occurs several years after treatment, and continued long-term follow-up with an endocrinologist is important. You may require hormone replacement therapy.

Medical Therapy for Nelson’s Syndrome

Medication for Nelson's SyndromeMedical therapies for the treatment of Nelson’s syndrome are currently limited, but include:

  • Somatostatin-analogs (SSAs). These medications are typically used to treat acromegaly. A small number of Nelson’s syndrome patients may respond.
  • Cabergoline. This medication is typically used to treat prolactinomas; you may require a very high dose.
  • Temozolomide. This is a type of chemotherapy used to treat primary brain tumors called glioblastoma.

If you require medication to treat Nelson’s syndrome, our endocrinologists will monitor you closely.

Myth: “Each Person Requires the Same Dose of Steroid in Order to Survive…

Myth: “Each person requires the same dose of steroid in order to survive with Secondary or Primary Adrenal Insufficiency”

myth-busted

Fact: In simple terms, Adrenal Insufficiency occurs when the body does not have enough cortisol in it. You see, cortisol is life sustaining and we actually do need cortisol to survive. You have probably seen the commercials about “getting rid of extra belly fat” by lowering your cortisol. These advertisements make it hard for people to actually understand the importance of the function of cortisol.

After a Cushing’s patient has surgery, he/she goes from having very high levels of cortisol to no cortisol at all. For pituitary patients, the pituitary, in theory, should start working eventually again and cause the adrenal glands to produce enough cortisol. However, in many cases; the pituitary gland does not resume normal functioning and leaves a person adrenally insufficient. The first year after pit surgery is spent trying to get that hormone to regulate on its own normally again. For a patient who has had a Bilateral Adrenalectomy (BLA), where both adrenal glands are removed as a last resort to “cure” Cushing’s; his/her body will not produce cortisol at all for his/her life. This causes Primary Adrenal Insufficiency.

All Cushing’s patients spend time after surgery adjusting medications and weaning slowly from steroid (cortisol) to get the body to a maintenance dose, which is the dose that a “normal” body produces. This process can be a very long one. Once on maintenance, a patient’s job is not over. He/She has to learn what situations require even more cortisol. You see, cortisol is the stress hormone and also known as the Fight or Flight hormone. Its function is to help a person respond effectively to stress and cortisol helps the body compensate for both physical and emotional stress. So, when faced with a stressor, the body will produce 10X the baseline levels in order to compensate. When a person can not produce adequate amounts of cortisol to compensate, we call that Adrenal Insufficiency. If it gets to the point of an “Adrenal Crisis”, this means that the body can no longer deal and will go into shock unless introduced to extremely high levels of cortisol, usually administered through an emergency shot of steroid.

There are ways to help prevent a crisis, by taking more steroid than the maintenance dose during times of stress. This can be anything from going to a family function (good stress counts too) to fighting an infection or illness. Acute stressors such as getting into a car accident or sometimes even having a really bad fight require more cortisol as well.

It was once believed that everyone responded to every stressor in the exact same way. So, there are general guidelines about how much more cortisol to introduce to the body during certain stressors. For instance, during infection, a patient should take 2-3X the maintenance dose of steroid (cortisol). Also, even the maintenance dose was considered the same for everyone. Now a days, most doctors will say that 20 mg of Hydrocortisone (Steroid/Cortisol) is the appropriate maintenance dose for EVERYONE. Now, we know that neither is necessarily true. Although the required maintenance dose is about the same for everyone; some patients require less and some require more. I have friends who will go into an adrenal crisis if they take LESS than 30 mg of daily steroid. On the other hand, 30 mg may be way too much for some and those folks may even require LESS daily steroid, like 15 mg. Also, I want to stress (no pun intended) that different stressors affect different people differently. For some, for instance, an acute scare may not affect them. However, for others, receiving bad news or being in shock WILL put their bodies into crisis. That person must then figure out how much additional steroid is needed.

Each situation is different and each time may be different. Depending on the stressor, a person may need just a little more cortisol or a lot. Every person must, therefore, learn their own bodies when dealing with Adrenal Insufficiency. This is VERY important! I learned this the hard way. As a Clinical Psychologist; I assumed that my “coping skills” would be enough to prevent a stressor from putting me into crisis. That was FAR from the truth! I have learned that I can not necessarily prevent my body’s physiological response to stress. People often ask me, “BUT you are a psychologist! Shouldn’t you be able to deal with stress?!!!!” What they don’t realize is that my BODY is the one that has to do the job of compensating. Since my body can not produce cortisol at all, my job is to pay close attention to it so that I can take enough steroid to respond to any given situation. We all have to do that. We all have to learn our own bodies. This is vitally important and will save our lives!

To those we have lost in our community to Adrenal Insufficiency after treatment of Cushing’s, Rest in Peace my friends! Your legacies live on forever!

Myth: After a “cure” for Cushing’s, everyone heals and goes back to normal.

Myth: After a “cure” for Cushing’s, everyone heals and goes back to normal. All Cushing’s patients can easily heal with no repercussions after Cushing’s. After pituitary surgery or a Bilateral Adrenalectomy (BLA), life is great and being “cured” means having a “normal” life! After all, surgery is a “cure” and about 6 weeks later, you are back to normal. “Say, you had surgery XYZ long ago! Shouldn’t you be better by now?!!!!”

Fact: I can not even tell you how many people asked me “aren’t you better yet?!” after both of my surgeries! There are too many to count! There is a misperception that surgery means a cure and therefore, healing should happen magically and quickly. No! No! No! This is far from the truth.

The sad reality is that even some medical doctors buy into this myth and expect quick healing in their patients. However, they are not living in their patients bodies nor have they obviously read the extensive research on this. Research has shown that the healing process after surgery is a long and extensive one. One endocrinologist, expert from Northwestern, even referred to the first year after pituitary surgery for patients as “the year from hell”! He literally quoted that on a slide presentation.

It takes at least one year after pituitary surgery, for instance, to even manage hormones effectively. Surgery is invasive and hard. However, the hardest part comes AFTER surgery. This is when the body is compensating for all of the years of hormonal dysregulation and the patient is trying to get his/her levels back to normal.

There is a higher rate of recurrence of Cushing’s then we once thought. This means that after a patient has achieved remission from this illness, it is likely to come back. In these cases, a patient faces other treatments that may include radiation, the same type of surgery, or an alternative surgery.

For many pituitary patients who experience multiple recurrences, the last resort is to attack the source by removing both adrenal glands. This procedure is known as a Bilateral Adrenalectomy or BLA. In these cases, it is said that the patient “trades one disease for another”, now becoming adrenally insufficient and having Addison’s Disease. Both Pituitary and Adrenal patients are faced with a lifetime of either Secondary or Primary Adrenal Insufficiency.

Adrenal Insufficiency is also life threatening and adrenal crises can potentially lead to death. Additionally, research says that BLA patients take, on average, 3-5 years for their bodies to readjust and get anywhere near “normal”. Most patients will tell you that they never feel “normal” again!

Think of these facts the next time you feel tempted to ask your friend, family, or loved one, “why is it taking so long to get better after surgery?”. Remember that in addition to the aforementioned points; problems from Cushing’s can linger for years after surgery! One Cushing’s patient stated, “I’m 5 years post-op and I STILL have problems!” This mirrors the sentiments of many of us in the Cushing’s community. Please be conscious of this when supporting your loved one after treatment.
