A CASE OF EXTRAMEDULLARY HEMATOPOIESIS IN THE NONFUNCTIONING ADRENOCORTICAL ADENOMA

Abstract

Reported is a case of extramedullary hematopoiesis in the nonfunctioning adrenocortical adenoma. This patient was a 64-year-old woman who was found to be with a right adrenal mass with calcification by CT scan incidentally. The labolatory data including ACTH and adrenal endocrine studies were all within normal limits. Under US guidance, needle biopsy of the right adrenal mass was performed and the specimens revealed adrenocortical adenoma. A right adrenalectomy was performed under diagnosis of nonf unctioing adrenocortical adenoma. Pathologically, there were two distinct histological components, a large adrenocortical adenoma with calcification and a smaller extramedullary hematopoiesis.
Nonfunctioning adenocortical adenoma found incidentally is increasing, but we have found no reports of its association with extramedullary hematopoiesis or myelolipoma.
