Leiomyoma of the epididymis: case report

Herein, we report on a rare case of leiomyoma of the epididymis. The case we present involved a 55-year-old patient who had had a painless left scrotal mass for 20 years. The mass was round and elastic and measured about 2 x 2 x 2 cm. We recognized the mass as a benign tumor by scrotal ultrasonography and performed an organ salvage operation for this patient. The final pathologic diagnosis of the mass was leiomyoma. Our report includes a detailed description of the ultrasonographic characteristics of this disease as well as a review of the literature. In general, sharp acoustic shadows with central hypoechoic lesions in heterogenous parenchyma are the distinctive characteristics of leiomyoma of the epididymis. We also discuss the possibility of a testis salvage operation for this type of disease. We conclude that the ultrasonographic characteristics can serve as an important guide for the surgeon to consider an organ salvage operation in cases of a painless scrotal mass.
