Epididymal leiomyoma

Michail Platanas, Ioannis Solinis, Eftychios Stavroulakis


A 68-year-old patient presented at the urology department due to the aggravation of a scrotal enlargement. The clinical examination revealed an induration of the right testis and oedema in its lower pole and in the right epididymal tail. The ultrasonographic imaging of the scrotum showed an oval-shaped, non-homogeneous mass, 3 cm in diameter, with localised necrotic areas. Our patient underwent an excision of the lesion. Visually, the histopathological examination revealed a whitish tumour of about 4 cm in diameter, with a  solid elastic composition,  while microscopy showed a tumour consisting of smooth muscle fibres (leiomyoma). Leiomyomas are benign neoplasms that can originate from any structure or organ containing smooth muscle fibres. Most urogenital system leiomyomas are identified in the renal capsule, but they have also been reported in the epididymis, the spermatic cord and the fibrous layer. Leiomyomas are a very rare form of neoplasm. It is very difficult to set a precise preoperative diagnosis, so the patient is often subjected to surgery to investigate the tumour.
