title: A papilloma of epididymis of Müllerian vestigial origin.
abstract: A 20 mm diam. nodule attached to the lower pole of the epididymis was found in a 48-year-old man presenting with recurrent hydrocele. Histology showed a benign papillary tumour of a type apparently not previously described. It is believed to have arisen from Müllerian remnants.
