Hyperandrogenism secondary to testicular cancer typically arises in patients in whom Leydig cell hyperplasia or neoplasia can be identified. Additionally, benign and malignant adrenocortical tumors can also present with signs and symptoms of hyperandrogenism. We report a case of a 40-year-old gentleman who experienced several months of weight gain, worsening gynecomastia, and mood changes secondary to high testosterone and estradiol levels. Workup initially was negative for testicular malignancy and positive for a benign-appearing lesion in the adrenal gland. Despite adrenalectomy, symptoms continued to persist and ultimately a testicular cancer without Leydig cell involvement was identified.
