We report the case of a benign feminizing adrenal tumor in a male patient. To our knowledge, only 2 other cases of benign, estrogen-only–secreting adrenal tumors have been reported.Case Report: A 44-year-old male with a history of hypertension presented to his primary care physician with chest tenderness, fatigue, and erectile dysfunction. Hormonal workup and imaging identified an estrogen-only–secreting adrenal adenoma. The adenoma was removed via laparoscopic adrenalectomy, and the patient had a normal postoperative course. Pathologic findings were an adrenal cortical adenoma with a Weiss score of 0 and a Ki-67 score of 0%. At 6-month follow-up, the patient's symptoms had significantly improved, and his previously abnormal sex hormone levels were within normal limits.Conclusion: Given the ambiguity in distinguishing between malignant and benign feminizing adrenal tumors, we suggest that radiologic (via Hounsfield units), clinical (via trending hormone levels), and histopathologic (via Weiss and Ki-67 scores) findings are sufficient to confirm the benign nature of this commonly malignant tumor.
