Corticomedullary mixed tumor of the adrenal gland with concurrent adrenal myelolipoma.
We report the case of a corticomedullary mixed tumor of the adrenal gland in a 55-year-old woman with a left adrenal mass who presented with mild symptoms of Cushing syndrome and an elevated urinary cortisol level. The patient underwent a left adrenalectomy. A well-circumscribed 2.5-cm mass, composed of an admixture of adrenal cortical cells and pheochromocytes, and an incidental 0.7-cm myelolipoma were present in the resected left adrenal gland. The diagnosis of adrenal corticomedullary mixed tumor was confirmed by both immunohistochemistry and electron microscopy. To our knowledge, this is the eighth well-documented report of this rare tumor.
