Adrenokortikal adenomda myelolipomatöz değişiklikler

Myelolipoma is a rare benign tumor which is generally detected incidentally. The tumor consists of mature fat tissue and hematopoietic cells that resemble bone marrow. The coexistence of myelolipoma and non-functional adrenocortical adenoma in the same gland is exceedingly rare. We herein present two cases of adrenal myelolipoma in association with non-functional adrenocortical adenoma in left adrenal gland of a 62-year-old woman and non-functional adrenocortical adenoma combined with myelolipoma and endothelial cyst, in right adrenal gland of a 73-years-old man. Microscopically, in the central of the tumor, there was a myelolipomatous area composed of adipocytes and hematopoietic cells surrounded by sheets of adenoma cells. The histopathological diagnosis was “myelolipomatous changes within a non-functional adrenocortical adenoma”. The cases are presented here with their rarity and pathological differential diagnosis.
