Myelolipoma of the adrenal gland associated with contralateral renal cell carcinoma: case report and review of the literature.

Adrenal myelolipoma is a rare benign hormonally inactive tumor. It is frequently detected incidentally on new imaging procedures, such as sonography and computerized tomography and, thus, the question of treatment arises. The association of myelolipomas with obesity, hypertension and malignant tumors has been described previously. We report the second case of myelolipoma associated with renal cell carcinoma. Pathogenesis, differential diagnosis and therapy are discussed.
