Rare Nasal Cancer May Have Caused Cushing’s Syndrome

Posted on April 8, 2026 by MaryO

A very rare case of Cushing’s syndrome developing as a result of a large and also rare cancer of the nasal sinuses gives insights into how to screen and treat such an anomaly, of which fewer than 25 cases have been reported in literature.

Paraneoplastic esthesioneuroblastoma (ENB), a very rare type of nasal tumor, may sometimes produce excess adrenocorticotrophic hormone (ACTH), leading to symptoms of Cushing’s syndrome, according to a recent case report that describes a case of ACTH-secreting ENB. The report aims to demonstrate the importance of recognizing its pathophysiology and treatment.

The case report, “A Case of Cushing’s Syndrome due to Ectopic Adrenocorticotropic Hormone Secretion from Esthesioneuroblastoma with Long Term Follow-Up after Resection,” was published in the journal Case Reports in Endocrinology.

It describes a 52-year-old Caucasian male who had a history of high blood pressure, severe weakness, abnormal production of urine, extreme thirstiness, and confusion.

He was scheduled to undergo surgery for a 7-centimeter skull base mass; the surgery was postponed due to severe high serum potassium concentrations and abnormally high pH levels. His plasma ACTH levels also were elevated and Cushing’s syndrome was suspected. Since imaging of the chest, abdomen, and pelvis did not show any ectopic (abnormal) sources of ACTH, the ENB was suspected to be the source.

Surgery was performed to remove the tumor, which was later found to be secreting ACTH. Consequently, following the procedure, his ACTH levels dropped to normal (below detection limit) and he did not need medication to normalize serum potassium levels. He then underwent subsequent chemoradiation and has shown no sign of recurrence 30 months after the operation, which is considered to be one of the longest follow-up periods for such a case.

Researchers declared it “a case of olfactory neuroblastoma with ectopic ACTH secretion that was treated with resection and adjuvant chemoradiation.”

“Given the paucity of this diagnosis, little is known about how best to treat these patients and how best to screen for complications such as adrenal insufficiency and follow-up,” they wrote. “Our case adds more data for better understanding of this disease.”

Abstract

Cushing’s syndrome (CS) is a disease which results from excessive levels of cortisol in the human body. The disorder is associated with various signs and symptoms which are also common for the general population not suffering from compound hypersecretion. Thus, more sensitive and selective methods are required for the diagnosis of CS.

This follow-up study was conducted to determine which steroid metabolites could serve as potential indicators of CS and possible subclinical hypercortisolism in patients diagnosed with so called non-functioning adrenal incidentalomas (AIs).

Urine samples from negative controls (n = 37), patients with CS characterized by hypercortisolism and excluding iatrogenic CS (n = 16), and patients with non-functioning AIs with possible subclinical Cushing’s syndrome (n = 25) were analyzed using gas chromatography-mass spectrometry (GC/MS) and gas chromatograph equipped with flame ionization detector (GC/FID). Statistical and multivariate methods were applied to investigate the profile differences between examined individuals. The analyses revealed hormonal differences between patients with CS and the rest of examined individuals.

The concentrations of selected metabolites of cortisol, androgens, and pregnenetriol were elevated whereas the levels of tetrahydrocortisone were decreased for CS when opposed to the rest of the study population. Moreover, after analysis of potential confounding factors, it was also possible to distinguish six steroid hormones which discriminated CS patients from other study subjects.

The obtained discriminant functions enabled classification of CS patients and AI group characterized by mild hypersecretion of cortisol metabolites. It can be concluded that steroid hormones selected by applying urinary profiling may serve the role of potential biomarkers of CS and can aid in its early diagnosis.

Froedtert and MCW researchers investigate Cushing syndrome incidence in bariatric surgery patients

Posted on January 29, 2026 by MaryO

Researchers at the Medical College of Wisconsin determined that Cushing syndrome, an endocrine disorder, may be the potential cause for weight gain and metabolic complications for patients who have undergone bariatric surgery for obesity. The study, published in the journal Obesity Surgery, was conducted by Ty B. Carroll, MD, assistant professor of endocrinology; James W. Findling, MD, FACP, professor of endocrinology ; and Bradley R. Javorsky, MD, assistant professor of endocrinology. The physicians practice at Froedtert Hospital in Wauwatosa and Community Memorial Hospital in Menomonee Falls.

Cushing syndrome can occur when the human body is exposed to high levels of cortisol for an extended period of time. Cortisol is a hormone in the body which affects blood pressure regulation and cardiovascular system functions. Cortisol also helps regulate the body’s conversion of proteins, carbohydrates and fats from diet into usable energy. However, when the level of cortisol becomes too high, Cushing syndrome can develop.

Cushing syndrome is associated with a variety of symptoms including weight gain and fatty tissue deposits in the body. According to the American Association of Neurological Surgeons, 10 to 15 million people are affected each year by Cushing syndrome.

Bariatric surgery is a procedure performed to help with extreme cases of obesity. Weight loss is achieved by reducing the size of the stomach with a gastric band, removal of a portion of the stomach or resecting and rerouting the small intestine to a small stomach pouch. Bariatric surgery is often used as an option for individuals unable to lose weight through diet and exercise, or have serious health problems caused by obesity.

According to the American Society for Metabolic and Bariatric Surgery, 179,000 bariatric surgeries were performed in the U.S. in 2013. However, despite successes in normal weight loss cases, bariatric surgery does not provide long term weight loss for individuals diagnosed with Cushing syndrome. Cushing syndrome often goes undiagnosed as a potential cause for weight gain and metabolic complications until after the surgery is performed.

MCW researchers in this study analyzed the incidence of Cushing syndrome in patients who underwent bariatric surgery for weight loss. During the investigation, the researchers performed a retrospective chart review on a series of 16 patients diagnosed with Cushing syndrome from five tertiary care centers in the U.S. who underwent bariatric surgery. The results from the study found 12 of the analyzed patients were not diagnosed with Cushing syndrome prior to their bariatric surgery. The remaining four patients had Cushing syndrome surgery prior to bariatric surgery, without recognition that their Cushing syndrome was persistent until after the weight loss surgery. The findings from the research indicate that Cushing syndrome may be often overlooked in patients undergoing bariatric surgery.

According to the researchers, testing for Cushing syndrome should be performed prior to bariatric surgery in patients with persistent hypertension, diabetes mellitus or excessive weight regain.

Cushing’s Syndrome Subtype Affects Postoperative Time to Adrenal Recovery

Posted on January 25, 2026 by MaryO

Berr CM. J Clin Endocrinol Metab. 2014;doi:10.1210/jc.2014-3632.

January 16, 2015

In patients undergoing curative surgical tumor resection for Cushing’s syndrome, the time to recovery of adrenal function is contingent upon the underlying etiology of the disease, according to recent findings.

In the retrospective study, researchers reviewed case records of 230 patients with Cushing’s syndrome. All patients were seen at a tertiary care center in Munich between 1983 and 2014, whose cases were documented in the German Cushing’s Registry. Patients were divided into three subgroups of Cushing’s syndrome: Cushing’s disease, adrenal Cushing’s syndrome and ectopic Cushing’s syndrome.

After applying various exclusion criteria, the researchers identified 91 patients of the three subgroups who were undergoing curative surgery at the hospital. The patients were followed for a median of 6 years. The researchers defined adrenal insufficiency as the need for hydrocortisone replacement therapy, and collected this information from patient records and laboratory results.

The duration of adrenal insufficiency was calculated as the interval between successful surgery and the completion of hydrocortisone replacement therapy. Cushing’s syndrome recurrence was defined as biochemical and clinical signs of hypercortisolism.

The researchers found a significant difference between Cushing’s syndrome subtypes in the likelihood of regaining adrenal function within 5 years of follow-up: The probability was 82% in ectopic Cushing’s syndrome, 58% in Cushing’s disease and 38% in adrenal Cushing’s syndrome (P=.001). Among the 52 participants who recovered adrenal function, the median type to recovery also differed between subtypes and was 0.6 years in ectopic Cushing’s syndrome, 1.4 years in Cushing’s disease and 2.5 years in adrenal Cushing’s syndrome (P=.002).

An association also was found between younger age and adrenal recovery in the Cushing’s disease participants (P=.012).

This association was independent of sex, BMI, symptom duration, basal adrenocorticotropic hormone and cortisol levels. No association was seen between adrenal recovery and length of hypercortisolism or postoperative glucocorticoid replacement dosage.

“It is the main finding of this series that the median duration of tertiary adrenal insufficiency was dependent on the etiology of [Cushing’s syndrome]: It was shortest in the ectopic [Cushing’s syndrome], intermediate in [Cushing’s disease] and longest in adrenal [Cushing’s syndrome] caused by unilateral cortisol producing adenoma,” the researchers wrote. “The significant difference to [Cushing’s disease] is an unexpected finding since by biochemical means cortisol excess is generally less severe in adrenal [Cushing’s syndrome]. If confirmed by others, our data have clinical impact for the follow-up of patients after curative surgery: Patients should be informed that adrenocortical function may remain impaired in benign conditions such as cortisol-producing adenoma.”

Some Lifestyle Tips for Cushing’s Syndrome

Posted on January 22, 2026 by MaryO

There are some ideas in the post below and some at http://www.cushings-info.com/index.php?title=Help_Yourself,_Part_1 (and also parts 2 and 3!)

Do you have any other helpful tips for the New Year?

Below is from https://www.endocrineweb.com/conditions/cushings-syndrome/4-lifestyle-tips-cushings-syndrome

As part of your overall Cushing’s syndrome treatment plan, there are some lifestyle tips you can incorporate to help you live well with Cushing’s syndrome.

Below are 4 lifestyle tips you can integrate into your recovery plan from Cushing’s syndrome. Have a conversation with your doctor before making any major changes, such as starting to exercise regularly.

  1. Eat smart. Make sure you’re eating nutritious foods. Of course, you should focus on eating fruits and vegetables, which are high in anti-oxidants, but also eat whole grains, lean protein, and healthy fats. These foods fuel your body by giving you healthy doses of energy.

    Also, be sure you get enough calcium and vitamin D in your diet. These nutrients help strengthen bones (important because bone loss is common with people who have Cushing’s syndrome). If you don’t get enough of these in your diet, talk to your doctor about taking calcium and vitamin D supplements.

    A registered dietitian (RD) can help you create a balanced meal plan—the key word here is “balanced.” Yes, you can still eat the foods you love (in moderation), but it’s important to eat foods that boost your health. An RD can also help you lose extra weight you gained from Cushing’s syndrome.

  2. Exercise gently. Exercise plays a significant role in any healthy lifestyle, but it’s important for you not to rush into it. Even if you think you’re feeling better, your body still needs time to heal.

    Start off slowly-you may want to try low—impact exercise, such as water aerobics, tai chi, or yoga. These exercises gently re-build your muscles and joints. From there, you can work up to a more moderate-paced exercise routine. You can also work with a personal trainer who can customize a workout plan for you.

    Exercising should be comfortable. If you experience pain or any new symptoms when exercising, talk to your doctor right away.

  3. Keep tabs on your mental health. Your mental health can take a toll when you have Cushing’s syndrome—depression is common. If you feel blue or you don’t feel like doing the things you used to and you’re not sure why, don’t ignore it. Talk to your doctor—he or she can recommend a psychologist who can help you cope with your feelings throughout your recovery.

    You may also want to keep a journal to record how you feel on a day-to-day basis.

  4. Give yourself a break. Don’t be hard on yourself as your body recovers from Cushing’s syndrome. It’s important to get plenty of rest, relaxation, and sleep. Treat yourself to a gentle massage, warm bubble bath, or listen to soothing music. Now’s not the time to push yourself—respect your body and its limits.

Incorporating these lifestyle tips into your routine can not only help you live well, but they can help you thrive with Cushing’s syndrome.
