Pure cutaneous paratesticular leiomyosarcoma of the scrotum: A rare case report.

Leiomyosarcoma (LMS) is a malignant mesenchymal neoplasm arising from the smooth muscle. Paratesticular LMSs are commonly located in the epididymis or spermatic cord. Pure scrotal cutaneous paratesticular LMS arising from the dartos muscle is very rare. Less than 40 cases have been reported in the literature to date. We report a case of pure scrotal cutaneous LMS in a 45-year-old patient.
