Testosterone- and Cortisol-secreting Oncocytic Adrenocortical Adenoma in the Pediatric Age-group

Oncocytic tumors are epithelial neoplasms that occur in various organs, including adrenal glands. Oncocytic adrenocortical adenomas and carcinomas are uncommon but well-known pathological entities in adults. However, generally oncocytic tumors, particularly in the adrenal glands, are very rare in the pediatric age-group. Most oncocytic adrenal tumors are not functional. We present a rare case of right-sided, functional oncocytic adrenocortical adenoma in a 5-year-old boy, who presented with clinical manifestations of precocious puberty and Cushing syndrome. Laparoscopic adrenalectomy showed a well-defined mass weighing 8.4 g and measuring 3 cm in maximum dimension. Histological examination demonstrated no features suggestive of aggressive biological behavior. The patient showed no evidence of recurrent or metastatic disease and continued to have normal serum hormonal levels 28 months following the surgery. In this report, we discuss the clinicopathological characteristics of this rare pathological entity and briefly review the literature on functional oncocytic adrenal tumors in the pediatric population.
