The first laparoscopic resection of an aldosterone-secreting adrenocortical oncocytoma in a child

Abstract

Oncocytomas of the adrenal cortex are usually benign and nonfunctional, consisting of oncocytes in which the cytoplasm becomes eosinophilic due to the accumulation of abnormal mitochondria. Oncocytomas can exist in many organs and are frequently found in the salivary gland, kidneys, thyroid gland, parathyroid gland, and hypophysis. Functioning oncocytomas are very rarely observed in children, and no more than ten cases have been reported in the literature. Here, we present the first report of laparoscopic excision of an aldosterone-secreting adrenocortical oncocytoma in a child. • Oncocytomas of the adrenal cortex are usually benign and nonfunctional tumors consisting of oncocytes in which their cytoplasm becomes eosinophilic due to accumulation of abnormal mitochondria. • Pediatric hormone-secreting adrenocortical oncocytomas are very rare in the literature and difficult to diagnose. • This is the first report of a laparoscopic excision of an aldosterone-secreting adrenocortical oncocytoma in a child. • Laparoscopic adrenalectomy can be performed safely for these rare adrenal tumors in children.
