Epididymal leiomyoma: a benign intrascrotal tumour

Abstract

Physicians will be rarely confronted with epididymal tumours. These represent only 5% of intrascrotal tumours and are mostly (75%) benign. We report the case of a 50-year-old white male who was presented with a 5-year history of a slow-growing, left scrotal mass, noted through self-examination. Ultrasound study of the scrotum identified a well-circumscribed paratesticular mass. On inguinal surgical exploration, a solid, encapsulated, grey-white mass at the tail of the left epididymis was identified and excised, with intra-operative pathological consultation showing no signs of malignancy. The diagnosis of an epididymal leiomyoma was determined through subsequent immune-histopathological analysis. Diagnostic steps preceding operative exploration of a paratesticular, epididymal tumour are briefly analysed and physicians are encouraged to avoid a radical approach, without prior pathological consultation. Epididymal leiomyomas are benign tumours that can be cured through simple, organ-preserving surgical excision.
