Leiomyosarcoma of the scrotum: a case report and literature review.

Leiomyosarcoma (LMS) is one of the most common forms of soft tissue sarcoma with approximately 2,500 cases per year in the United States. The symptoms LMS vary depending upon the location, size, and spread of the tumor. In early stages, it may not be associated with any obvious symptoms so diagnosis and treatment may be delayed. In some cases, it can grow quickly and behave aggressively. Most types of LMS occur in the abdomen or in the uterus; although, scrotal LMS can be a very rare presentation of the disease. Here we present our case of a large, ulcerated scrotal LMS originating from subcutaneous tissue but not invading spermatic cord or tunica. Radical orchiectomy with high ligation of spermatic cord was performed, and patient had an uneventful postoperative course. This disease entity remains rare in the literature, and warrants larger studies in order to better understand treatment and oncologic outcomes. When LMS is identified early and is removed by surgical excision, prognosis can be good and full recovery quite likely. When LMS is already large or has spread to other parts of the body, treatment is relatively more complex and the prognosis poor. Hence, prompt diagnosis and treatment of genitourinary LMS require prompt attention, referral to tertiary, referral center should be strongly considered.
