Adrenocortical carcinosarcomas are rare aggressive neoplasms; only a few have been reported to date, all with dismal prognosis. These were reported as having varying morphology. We have encountered a case of adrenal carcinosarcoma with an undifferentiated component bearing similarities to primitive neuroectodermal tumors and other areas of oncocytic differentiation. The 48-year-old woman patient presented with abdominal pain and unintended, excessive weight loss. Computed tomographic imaging revealed a tumor located adjacent to the liver and kidney necessitating a partial nephrectomy and hepatectomy. Histologically, the tumor exhibited malignant features. Melan-A, inhibin, calretinin, cytokeratin AE1/AE3, synaptophysin, and neuron-specific enolase were positive immunohistochemically. The patient developed metastasis within 2 months of surgery and is currently alive with disease after chemotherapy. Adrenal carcinosarcoma is a rare highly aggressive malignancy with a wide morphologic spectrum. Recognition of variant morphology and applying correct immunohistochemical studies will aid in reaching an accurate diagnosis.
