Gynecomastia: An Uncommon but Important Clinical Manifestation for Testicular Tumors

Abstract: Gynecomastia is a benign enlargement of male breast tissue due to the proliferation of the ductal component. It can be physiological or pathological. Gynecomastia can be a sign for testicular tumors including sex-cord stromal tumors and germ cell tumors. Testicular physical examination in combination with testicular untrasonography and serum germ cell tumor markers when necessary in the presence of gynecomastia can help to reach a correct diagnosis.
