Scrotal pain as the first manifestation of scrotal leiomyoma: a case report.

Primary scrotal leiomyoma is derived from smooth muscle cells of tunica dartos. A 37-year-old Thai man, barber by profession, presented with left scrotal pain and subsequently, a solid mass is reported. As a relatively rare neoplasm, the initial diagnosis and differential diagnosis are intricate. The management was surgical excision. The well circumscribed 1 cm mass appeared as homogeneous, whorled-like, with interlacing fascicles of spindled muscle cells, and a strong positive desmin immunoreactivity. Upon follow-up, pain had disappeared one year after surgery. Reassurance and careful re-examination to reduce anxiety was also needed.
