副腎皮質腺腫に合併した両側精巣Leydig cell tumorの1例

Abstract

A case of bilateral testicular Leydig cell tumor with left adrenocortical adenoma in a 27-year-old male is presented. He underwent bilateral radical orchiectomy, and was diagnosed with a malignant Leydig cell tumor. Computed tomography revealed left adrenal mass and primary adrenal tumor or metastatic malignant Leydig cell tumor was suspected. Left adrenalectomy was performed and the histopathological diagnosis was adrenal cortical adenoma. The adrenal cortex and testicle are of common mesodermal origin and the histologic pattern may overlap. Examination of the adrenal gland is necessary for patients with testicular Leydig cell tumor. We review and briefly discuss a case recently reported in Japan.
