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.

ACTH-producing Lung Tumors Hard to Detect, But May Be Cured with Surgery

Ectopic Cushing’s syndrome can be challenging to diagnose, especially when it comes identifying the problem source. But appropriate hormone management protocols, used in combination with advanced imaging methods, may help physicians identify ectopic ACTH-producing tumors.

The findings in a case report of a young man with ectopic Cushing’s syndrome were published in the International Journal of Surgery Case Reports, under the title “Case report: Ectopic Cushing’s syndrome in a young male with hidden lung carcinoid tumor.”

Cushing’s syndrome is caused by high amounts of glucocoticosteroids in the blood. The most common cause is a malfunction of the glands that produce these hormones. In some cases, however, the disease may be caused by tumors elsewhere in the body that have the ability to produce adrenocorticotropic hormone (ACTH).

In half of all Cushing’s patients, ectopic ACTH is produced by small lung cell carcinomas or lung carcinoids (a type of slow-growing lung cancer). But some tumors in the thymus and pancreas also have been found to produce ACTH.

Researchers at Damascus University Hospital in Syria presented the case of a 26-year-old man who had ectopic Cushing’s syndrome due to lung carcinoids.

The patient presented with increased appetite and rapid weight gain for more than a year. These were associated with headache, fatigue, proximal muscle weakness, and easy bruising. He had no family history of hormonal disorder.

Based on the initial physical and symptom evaluation, the clinical team suspected Cushing’s syndrome. Blood analysis revealed high levels of cortisol and ACTH hormones, which supported the diagnosis.

Administration of dexamethasone, a treatment used to inhibit the production of glucocoticosteroids by the pituitary gland, reduced cortisol levels within normal range, but not ACTH levels. This led to the diagnosis of ectopic Cushing’s syndrome.

The next step was to identify the tumor causing the syndrome. The team conducted imaging studies of the brain, chest, and abdomen, but found no tumor.

Because ectopic ACTH is commonly produced by lung cancers, the team then analyzed the patient’s lungs. Again, they failed to detect a tumor.

The patient was discharged with prescription of 200 mg of Nizoral (ketoconazole) once-daily, calcium, and vitamin D. After three months of treatment, he remained stable, with no evidence of symptom improvement.

At this point, the team decided to surgically remove both adrenal glands in an attempt to reduce the hormone levels. Treatment with prednisolone 5 mg and fludrocortisone 0.1 mg once daily was initiated, along with calcium and vitamin D.

Eighteen months later, the patient’s condition worsened and he required hospitalization.

Imaging tests targeting the neck, chest, and abdomen were conducted again. This time, physicians detected a 2 cm mass in the middle lobe of the right lung, which was removed surgically. Detailed analysis of the small tumor confirmed that it was the source of the excessive ACTH.

“ACTH secreting tumors can be very hard to detect,” the researchers stated. “Initial failed localization is common in ectopic ACTH syndrome and it is usually due to carcinoid.”

Cases where the ectopic ACTH production is caused by a carcinoid tumor can be challenging to diagnose because tumors are small and relatively slow-growing. Imaging data is often hard to analyze and the tumors can be confused with pulmonary vessels, the researchers explained.

“In such cases we should first aim to lower blood cortisol medically or through bilateral adrenalectomy to avoid Cushing’s complications,” which should then “be followed up through imaging studies (CT, MRI, scintigraphy or PET) to detect the tumor and resect it, which is the definitive treatment of these patients,” the researchers concluded.

Summary

A 23-year-old man presenting with florid Cushing’s syndrome was found to have high plasma ACTH and very high serum prolactin. Pituitary MRI showed a large invasive macroadenoma.

Low-dose cabergoline promptly suppressed both ACTH and prolactin levels within 2 weeks, with unexpected clinical and biochemical hypocortisolism requiring hydrocortisone replacement. Secondary hypogonadism was reversed. Clinical and biochemical remission of his Cushing’s syndrome together with significant shrinkage of his macroadenoma has been maintained for 1 year on cabergoline 0.5 mg twice weekly. Reduction in pituitary

Reduction in pituitary tumour volume and brisk fall in serum prolactin in response to low-dose cabergoline is regularly observed in patients with macroprolactinomas, but the concurrent fall in the plasma ACTH level and hypocortisolism was a pleasant surprise.

We assume that he most likely has a single bihormonal adenoma that is enriched with dopamine-2 receptors.
