Myoid Gonadal Stromal Tumor of the Testis: A Rare Sex Cord-Stromal Neoplasm in a Young Man.

Myoid gonadal stromal tumor is a rare subtype of testicular sex cord-stromal tumor characterized by a mixture of myoid and gonadal spindle cells. We present a 24-year-old man with a two-year history of chronic, intermittent dull pain in the left testicle. Work-up, management, pathology, and follow-up are reviewed. These tumors have demonstrated indolent behavior, typically benign; however, accurate diagnosis is essential to differentiate them from other more dangerous tumor types. Radical orchiectomy alone appears to be sufficient for the treatment of these tumors, with only short-term surveillance appearing adequate due to their indolent nature.
