Pediatric adrenocortical adenoma presenting with Cushing's syndrome

Cushing's syndrome (CS) in children is a rare disease, most frequently caused by either an adrenal tumor or a corticotropin-secreting pituitary adenoma. Its early detection and effective treatment are highly important to avoid the short-and long-term consequences of hypercortisolism. We report a case of a child with Cushing's syndrome resulting from an adrenocortical adenoma. Endocrinological data revealed adrenocorticotropin (ACTH) independent hypercortisolism. MRI scan of the adrenal glands showed a single, well-encapsulated tumor on the right adrenal gland with a diameter of 3.5 cm. Adrenal gland sparing surgery was performed with total excision of the tumor. The histological analysis confirmed the diagnosis of adrenal adenoma. The child was cured clinically and biochemically. The long-term follow-up of patients treated for Cushing's syndrome should include the adequate replacement of glucocorticoids and other steroid hormones, treatment of osteoporosis and other pathologic effects of hypercortisolism and long-term screening for the relapse of Cushing's syndrome.
