Abstract

Background

Ectopic ACTH-producing thymic carcinoid tumors are rare, but often behave aggressively with local invasion and distant metastasis. We herein report a case of ACTH-producing thymic typical carcinoid tumor with lymph node metastasis treated by surgery and postoperative radiation therapy.

Case presentation

A 61-year-old woman was admitted to be evaluated for hypoglycemia and hypokalemia. Laboratory data revealed elevation of serum cortisol and ACTH levels. Overnight administration of 8 mg dexamethasone did not suppress plasma ACTH. Chest CT demonstrated a tumor of 30 mm in diameter and enlargement of the lymph node at the anterior mediastinum. Ectopic ACTH syndrome was suspected and total thymectomy and lymph node dissection were performed. The histopathological examination indicated typical carcinoid tumor and mediastinal lymph node metastasis, and immunohistochemical staining was positive for ACTH. The plasma ACTH level decreased immediately after surgery. She received postoperative radiation therapy of 60 Gy.

Conclusion

Ectopic ACTH-producing thymic typical carcinoid tumors are rare, and it is important to consider this disease and perform appropriate treatment.

Background

Among adrenocorticotrophic hormone (ACTH)-dependent Cushing’s syndrome, 10–20% is due to nonpituitary tumors termed ectopic ACTH syndrome (EAS). The most common cause of EAS is small cell lung cancer, followed by thymic carcinoids. Thymic carcinoids are very rare neuroendocrine tumors that often complicate endocrine disorders. Although previously assumed to be variants of bronchopulmonary carcinoid tumors, they are generally more aggressive and difficult to treat. It is widely accepted that surgical resection is the only curative treatment for localized lesions, and the efficacy of chemotherapy and radiotherapy has not been well established.

We herein report a case of EAS caused due to a thymic typical carcinoid tumor successfully treated by surgery followed by radiation.

Case presentation

A 61-year-old woman visited her primary care doctor because of general malaise, face edema, skin pigmentation, insomnia, and polyuria. Blood examination revealed marked hypokalemia and impaired glucose tolerance. Bilateral adrenal enlargement was observed on abdominal ultrasonography, and she was referred to our hospital for further examination. Endocrine examination showed both elevated plasma cortisol (107.7 pg/mL) and ACTH levels (1100 pg/mL), and increased urinary excretion of free cortisol (6650 mcg/day) and 17-ketogenic steroids (78.7 mg/day). Plasma cortisol and ACTH levels were elevated without any diurnal rhythm. Plasma cortisol was not suppressed by the overnight 8-mg dexamethasone suppression test. There was no response of plasma ACTH or cortisol to exogenous corticotropin-releasing hormone (CRH). Other hormones of the pituitary, thyroid, and adrenal medulla were all in normal ranges. Thus, ectopic ACTH syndrome was strongly suggested.

Chest computed tomography (CT) demonstrated a tumor of approximately 30 mm in diameter and enlargement of the lymph node in the anterior mediastinum (Fig. 1). High accumulation of 18-fluorodeoxyglucose in the anterior mediastinum tumor (maximum standardized uptake value [SUV] 2.48) but not in the lymph node was observed on positron emission tomography (PET)/CT. Somatostatin receptor scintigraphy also revealed mild uptake in the tumor. Collectively, these data were consistent with a diagnosis of EAS caused by an anterior mediastinum tumor, possibly thymic carcinoid tumor. There was no abnormal finding indicating multiple endocrine neoplasia (MEN).

Before the operation, we administered 500 mg/day of metyrapone, and both ACTH and cortisol levels decreased to 68.5 pg/mL and 3.02 mcg/mL respectively. After 2 months of medical treatment, her symptoms were relieved and bilateral adrenal enlargement decreased. Under open thoracotomy by median sternotomy, she underwent total thymectomy, pericardial partial resection, dissection of the anterior regional and the right paratracheal lymph nodes, and sampling of the subcarinal lymph node. Histopathologically, the tumor consisted of round to spindle-shaped cells with high nucleus/cytoplasm ratios containing finely granular chromatin. Necrosis was absent, and mitotic figures were infrequent, with less than two per ten high-power fields (HPF). Tumor cells were positive for chromogranin A, synaptophysin, CD-56, and ACTH on immunohistochemistry (Fig. 2). The tumor had invaded the pericardium, and mediastinal lymph nodes were positive for metastasis. The final diagnosis was stage IVA (pT2N1M0) ACTH-producing thymic typical carcinoid tumor. The plasma ACTH level decreased to 14.8 pg/mL, less than normal, immediately after surgery (Fig. 3). Hydrocortisone was administered during the perioperative period and was gradually tapered, and finished 4 months after surgery. She received postoperative radiation therapy of 60 Gy. At 8 months after surgery, she showed no sign of Cushing’s syndrome or recurrence of the tumor without any medications.

Discussion

Ectopic ACTH-producing thymic carcinoid tumor is an extremely rare clinical condition, comprising 29% of all thymic carcinoids and 5–42% of all ectopic ACTH-producing syndrome [12]. It has been reported that radical surgical resection of the ACTH source is the only effective treatment [3]. Prior to surgery, medication therapy should be done to prevent perioperative complications and perform surgery when hormone values and symptoms are controlled. Furthermore, there is a risk of postoperative adrenal insufficiency; strict perioperative management is desirable.

Unlike pulmonary and other carcinoid tumors, thymic carcinoids often behave aggressively as an advanced disease with local invasion, lymph node metastasis, and distant metastasis because of the high proportion of atypical carcinoid tumors. Regarding ACTH-producing thymic tumors, Neary et al. reported three cases of well-differentiated ACTH-producing thymic neuroendocrine carcinomas, and the patients had no lymph node metastasis, recurrence, or death. On the other hand, nine cases of moderately differentiated ACTH-producing thymic neuroendocrine carcinomas almost had lymph node metastasis, and all patients had recurred [4]. However, our case was a typical carcinoid tumor with lymph node metastasis and local invasion.

As a surgical procedure, a median sternotomy approach is generally recommended because this enables excision of the entire thymus, perithymic fat, other affected mediastinal structure, and aggressive lymph node dissection. However, there is no standard for lymph node dissection in thymic epithelial tumors even though lymph node metastasis is an important prognostic factor. Hwang et al. recommended right paratracheal node dissection in addition to anterior regional lymph node dissection for TNM clinical stage II or higher diseases because they are crucial stations on the lymphatic pathway of thymic malignancies [5]. In the present case, we performed total thymectomy, followed by lymph node dissection of the anterior regional and right paratracheal nodes, and sampling of subcarinal lymph node via median sternotomy. The anterior mediastinal lymph nodes were positive for metastasis. Consequently, we considered the extent of lymph node dissection to be adequate, and radical resection was completed because the postoperative plasma ACTH level was successfully decreased. Although a good prognosis is expected by combined surgery and radiation, relatively high malignancy characteristics are observed compared with typical carcinoids, and strict follow-up is needed.

Conclusion

We report a rare case of ectopic ACTH-producing thymic typical carcinoid with local invasion and regional lymph node metastasis. Surgical resection was effective to control Cushing’s syndrome in this case, and nodal staging may help to guide adjuvant treatment, but systemic nodal dissection/sampling is yet to be standardized.

Cushing’s Patient Exhibits Cortisol-Secreting Lesions in Both Adrenal Glands

In rare cases, Cushing’s syndrome may be caused by cortisol-secreting masses in both adrenal glands, a case report shows.

The study with that finding, “ACTH-independent Cushing’s syndrome with bilateral cortisol-secreting adrenal adenomas: a case report and review of literatures” was published in BMC Endocrine Disorders.

Cushing’s syndrome results from the prolonged secretion of excess cortisol. While most cases are caused by tumors in the pituitary gland, up to 20 percent result from tumors in the adrenal glands.

Occasionally, Cushing’s syndrome is caused by masses in both adrenal glands, which may be similar or display different properties. “Determining the nature and function of bilateral adrenal masses is always a challenge in clinical practice,” researchers said.

Now, physicians at Sichuan University in China, reported the case of a 55-year-old woman who complained of difficulty breathing for more than 10 years.

The patient had developed obesity of the trunk and face over the past two years, and had been diagnosed with hypertension 10 years before. She also had high lipid levels for the past five years.

The patient was taking Avapro (irbesartan), Lopressor (metoprolol), Procardia XL (nifedipine), and statins for these disorders. No other health conditions or treatments were reported.

Physical examination showed a moon-shaped face, truncal obesity, and accumulation of fat in the back of the neck and upper back (aka buffalo hump). She also had discoloration of the lower limbs, with slight fluid accumulation and muscle weakness.

Routine blood analysis did not reveal significant changes, but hormone analysis showed high cortisol levels and low adrenocorticotropic hormone (ACTH) was low.

The amount of 24-hour urine-free cortisol was almost five times higher than the upper normal limit. Also, the patients had reduced response to corticosteroids treatment, showing even higher cortisol levels upon treatment with 1 mg dexamethasone. Additional evaluations revealed reduced bone mineral density, indicative of osteoporosis.

Together, the findings led to a diagnosis of ACTH-independent Cushing’s syndrome.

To identify what was causing Cushing’s syndrome, the team looked at the adrenal glands. They detected three lesions, one on the right side measuring 2.5 centimeters, and two on the left side, with 2.3 cm and 0.6 cm respectively. The masses in both sides were actively producing cortisol in similar proportions.

These results confirmed that the patient had Cushing’s syndrome induced by bilateral adrenal excessive cortisol secretion.

Because the patient had poor cardiac function, researchers planned a two-step operation. First, they removed the right adrenal gland laparoscopically, followed by the left adrenal gland two months later. The patient started replacement therapy with hydrocortisone, and her cortisol levels improved significantly, returning to normal levels. She also lost 4 kilograms (8.8 pounds) of body weight in the following year.

“The optimal treatment for patients with bilateral cortisol-secreting adenomas remains uncertain,” the researchers wrote. Although there are no reports of recurrence after surgical treatment, the long-term outcome of these patients remains unclear, and “lifelong follow-up of the patient is required,” they added.

Bilateral cortisol-secreting adrenal adenomas are rare, having been reported in only 15 other studies, the team wrote. Interestingly, some features reported in this study also were identified by other researchers, including the fact that bilateral cortisol-secreting adrenal lesions are more predominantly found in females during adulthood. Also, the size of the lesions commonly range between 1 to 5 centimeters when detected, and appear at approximately the same time in both adrenal glands.

Although there are no treatment guidelines for these cases, surgical removal of the lesions or adrenal glands, plus glucocorticoid replacement therapy, is the mostly used therapeutic approach. Importantly, the researchers noted that patients who underwent partial gland removal were able to withdraw from glucocorticoid replacement therapy during follow-up.

Cushing’s and Hairy Nipples

Hairy nipples are a common condition in women. The amount of hair on the nipples varies, but some women find that the hair becomes long, coarse, and dark, which can be distressing.

Hairy nipples are rarely a cause for concern and are usually not a sign of any underlying health issues. However, occasionally they can signify something more serious, in which case, it is essential to consult a doctor.

Almost every part of a person’s skin is covered in hair and hair follicles. On certain parts of the body, such as the top of the head, the hair usually grows longer and thicker, while on other parts, it is thin and transparent.

Fast facts on hairy nipples:

  • It is not known how common hairy nipples are or how many women have them.
  • Many women do not report the condition and instead manage it themselves.
  • It is possible for hair that used to be fine and light to turn coarse and dark with age.

Causes of hairy nipples in women

There are several underlying reasons that might cause nipple hairs to grow. These are:

Cushing’s syndrome

Cushing’s syndrome is another condition caused by hormonal imbalance. When it occurs, there is an excess of cortisol in the body. In this case, a person may experience several symptoms, such as:

  • increased hair growth
  • abnormal menstrual periods
  • high blood pressure
  • a buildup of fat on the chest and tummy, while arms and legs remain slim
  • a buildup of fat on the back of the neck and shoulders
  • a rounded and red, puffy face
  • bruising easily
  • big purple stretch marks
  • weakness in the upper arms and thighs
  • low libido
  • problems with fertility
  • mood swings
  • depression
  • high blood glucose level

Cushing’s syndrome is fairly rare, and the cause is usually associated with taking glucocorticosteroid medicine, rather than the body overproducing the hormone on its own.

It is possible, however, that a tumor in the lung, pituitary gland, or adrenal gland is the cause.

Also:

Hormonal changes and fluctuations

Hormonal changes in women can cause many different symptoms, one of which is changes in nipple hair growth and color.

Some common hormonal changes happen during pregnancy and menopause.

However, hormonal changes can also occur when a woman is in her 20s and 30s, which may cause nipple hair to change appearance or become noticeable for the first time.

Overproduction of male hormones

It is possible for hormonal imbalances to cause hairy nipples. Overproduction of male hormones, including testosterone, can cause hair growth, while other symptoms include:

  • oily skin that can lead to breakouts and acne
  • menstrual periods stopping
  • increase in skeletal muscle mass
  • male pattern baldness, leading to a woman losing hair on her head

If overproduction of male hormones is suspected, it is a good idea to make an appointment with a doctor who can confirm this with a simple test.

Polycystic ovary syndrome

Polycystic ovary syndrome (PCOS) occurs because of a hormonal imbalance. PCOS is a condition that affects the way the ovaries work.

Common symptoms of PCOS are:

  • infertility
  • irregular menstrual periods
  • ovarian cysts
  • excessive hair growth in unusual places, such as the nipples

PCOS is believed to affect around 1 in 5 women.

Medication

The side effects of particular medicines can cause unusual hair growth.

Medicines, such as testosterone, glucocorticosteroids, and certain other immunotherapy drugs may cause hairy nipples.

What are the treatment options?

Treatment for hairy nipples is not usually necessary for health reasons.

However, many women with the condition prefer to try and reduce or get rid of the appearance of hair on their nipples for cosmetic purposes.

There are several methods by which they can try and do this:

Trimming the nipple hair

Trimming the nipple hair may be enough to reduce its appearance. Small nail scissors are ideal, and hair can be cut close to the skin. It is essential to do this carefully and avoid catching the skin.

Trimming will need to be carried out regularly when the hair grows back.

Tweezing the nipple hair

Tweezing nipple hair is an effective way to get rid of unwanted nipple hair. However, this option can be painful as the skin around the nipple area is particularly soft and sensitive.

It is also important to bear in mind that the hair will return, and tweezing the hair increases the risk of infection and ingrown hairs.

Shaving the nipple hair

Shaving is another option to reduce the appearance of nipple hair. However, it is advisable to do so with caution to avoid nicking the sensitive skin.

This option also carries an increased risk of developing ingrown hairs and infection.

Waxing

Sugaring or waxing is a good hair removal option, though either one is likely to be painful. A salon is the best place to get this treatment type, as doing this at home may cause damage to the skin. Infection and ingrown hairs are again a risk.

Laser hair removal

These popular treatments can help to reduce the hair growth and slow or even prevent regrowth for a while. However, they can be painful, too.

Laser treatment is by far the most expensive option, as it will need to be performed by a plastic surgeon or cosmetic dermatologist.

Hormonal treatment

If a hormonal imbalance is the cause of hairy nipples, a doctor may prescribe or adjust a woman’s medication therapy to restore a healthy hormonal balance.

Other treatments and how to choose

The above treatments are all commonly used to remove and reduce nipple hair and usually have minimal side effects.

Bleaching or using hair removal cream to treat the condition, however, is not advised as these methods are usually too harsh for this sensitive area and may cause irritation and damage.

At what point should you see a doctor?

Hairy nipples in women are quite common, and there is usually no need to see a doctor. However, if they are accompanied by any other unusual symptoms, it is a good idea to make an appointment.

A doctor will be able to perform tests to determine whether an underlying cause, such as PCOS, is causing the growth of nipple hair. If so, they will give advice and medication therapy to help manage the condition.

A doctor will also be able to advise how to remove nipple hair safely.

Takeaway

For the majority of women, nipple hair may seem unsightly, but it is not a cause for any concerns about their health.

However, because some medical conditions can cause nipple hair to darken and grow, it is important to see a doctor if any other symptoms are experienced.

Nipple hair can usually be easily treated and managed, should a woman choose to try to remove the hair for cosmetic reasons.

Benefits of Medication Before Surgery for Cushing’s Syndrome Still Unclear

In Europe, nearly 20 percent of patients with Cushing’s syndrome receive some sort of medication for the disease before undergoing surgery, a new study shows.

Six months after surgery, these patients had remission and mortality rates similar to those who received surgery as a first-line treatment, despite having worse disease manifestations when the study began. However, preoperative medication may limit doctors’ ability to determine the immediate success of surgery, researchers said.

A randomized clinical trial is needed to conclusively address if preoperative medication is a good option for Cushing’s patients waiting for surgery, they stated.

The study, “Preoperative medical treatment in Cushing’s syndrome. Frequency of use and its impact on postoperative assessment. Data from ERCUSYN,” was published in the European Journal of Endocrinology. 

Surgery usually is the first-line treatment in patients with Cushing’s syndrome. But patients also may receive preoperative medication to improve cortisol excess and correct severe diseases occurring simultaneously with Cushing’s.

Multiple studies have hypothesized that preoperative medication can have a beneficial effect on patients who undergo surgery. However, data on the beneficial impact of medication on morbidity, and the immediate surgical and long-term outcomes in patients with Cushing’s syndrome, are limited and inconclusive.

So, researchers made use of the European Registry on Cushing’s Syndrome (ERCUSYN), the largest database that collects information on diagnosis, management, and long-term follow-up in Cushing’s patients.

The team set out to collect information of the prevalence of preoperative medication in Cushing’s patients throughout Europe, and whether it influences patients’ outcomes after surgery. It also aimed to determine the differences between patients who receive preoperative medication versus those who undergo surgery directly.

Researchers analyzed 1,143 patients in the ERCUSYN database from 57 centers in 26 countries. Depending on what was causing the disease, patients were included in four major groups: pituitary-dependent Cushing’s syndrome (68%), adrenal-dependent Cushing’s syndrome (25%), Cushing’s syndrome from an ectopic source (5%), and Cushing’s syndrome from other causes (1%).

Overall, 20 percent of patients received medication – ketoconazole, metyrapone, or a combination of both – before surgery. Patients with ectopic and pituitary disease were more likely to receive medication compared to patients whose disease stemmed from the adrenal glands. Preoperative treatment lasted for a median of 109 days.

Patients in the pituitary group who were prescribed preoperative medication had more severe clinical features at diagnosis and poorer quality of life compared to those who received surgery as first-line treatment. No differences were found in the other groups.

But patients with pituitary-dependent disease receiving medication were more likely to have normal cortisol within seven days of surgery, or the immediate postoperative period, compared to patients who had surgery without prior medication. These patients also had a lower remission rate.

Within six months of surgery, however, there were no differences in morbidity or remission rates observed between each group. Also, no differences were seen in perioperative mortality rates – within one month of surgery.

Interestingly, researchers noted that patients who took medication prior to surgery were less likely to be in remission immediately after surgery. The reason, they suggest, might be because the medication already had begun to improve the clinical and biochemical signs of the disease, “so changes that take place in the first week after surgery may be less dramatic.”

“A randomized trial assessing simple endpoints, such as length of hospital stay, surgical impression and adverse effects of surgery, is needed to conclusively demonstrate that [preoperative medication] is a valid option in patients waiting for surgical correction of hypercortisolism,” the team concluded.

Adrenal Gland Lump Led to 5-year-old Developing Cushing’s, Starting Puberty

Non-cancerous adrenal gland tumors can lead to rare cases of Cushing’s syndrome in young children and puberty starting years before it should, a case study of a 5-year-old boy shows.

Removing his right adrenal gland eliminated the problems, the Saudi Arabian researchers said.

Their report dealt with tumors in epithelial cells, which line the surface of many of the body’s structures and cavities.

The research, “Testosterone- and Cortisol-secreting Oncocytic Adrenocortical Adenoma in the Pediatric Age-group,” appeared in the journal Pediatric and Developmental Pathology.

Most tumors in adrenal gland epithelial cells are benign and generate normal levels of hormones. But there are cases when the tumors over-produce steroids and other kinds of hormones, including sex hormones. Sometimes the over-production can lead to Cushing’s syndrome.

The 5-year-old boy’s over-production of adrenal gland hormones led to both symptoms of Cushing’s syndrome and signs that he was starting puberty, the researchers said.

One reason the case was rare is that the average age when Cushing’s develops is 40, doctors say. Another is that epithelial adrenal gland tumors account for only 0.2 percent of all tumors in children, the researchers said.

Signs that the boy was starting puberty began appearing eight months before his parents took him for treatment. Doctors discovered he had the weight gain and rounded face associated with Cushing’s, but a battery of tests detected no other problems. No family members were experiencing the symptoms he was, doctors added.

Biochemical tests showed that the boy had a high level of cortisol in his blood, which doctors were unable to lower with the corticosteroid suppression medication dexamethasone.

Physicians also discovered that the boy had elevated levels of the male hormone testosterone, the cortisol precursor 17-hydroxyprogestrone, the cortisol-releasing hormone adrenocorticotropin, and another male hormone that the adrenal gland produces — dehydroepiandrosterone sulfate

In contrast, doctors discovered a below-normal level of luteinising, a sex hormone that the pituitary gland generates.

Another unusual manifestation of the boy’s condition was that his bone growth was that of a child a year older than he.

Doctors discovered a non-cancerous tumor in his right adrenal gland that they decided to remove. When they did, they discovered no evidence of bleeding, tissue scarring or cell death.

They put the boy on a hydrocortisone supplement, which they reduced over time and finally ended.

Twenty-eight months after the surgery, the boy showed no signs of Cushing’s disease or early puberty. And his weight, cortisol and adrenocorticotropin hormone levels were normal.

“To the best of our knowledge, our patient represents the first male patient” with a benign epithelial-cell adrenal gland tumor “in the pediatric population, with clinical presentation of precocious [early] puberty and Cushing’s syndrome,” the researchers wrote.

“As these tumors are exceptionally rare, reporting of additional cases and investigation of clinicopathological [disease] data are needed for better characterization of these tumors,” they wrote.
