Male adnexal tumour of probable Wolffian duct origin.

Male adnexal tumours of Wolffian duct origin are very rare. They have variable malignant potential and surgical excision is recommended. We report the case of a 56-year-old male who presented with a swelling in the perineum thought to be a haematoma as the result of a complication of a laparoscopic inguinal hernia repair. It recurred after incision and two attempts at drainage and was then completely excised. Histology revealed the lesion to be an adnexal tumour of probable Wolffian duct origin. To our knowledge there have only been two previous cases of male adnexal tumour of Wolffian duct origin reported in the literature.
