This lesion was excised from a 6 year old boy who presented with a history of swelling following a knock on the scrotum 4 months previously. The cyst was situated behind a normal right testis and extended into the inguinal region. Post-operative recovery was satisfactory.
The specimen is a lobulated elongated cystic mass 6 cm in length with a narrow stalk at the upper end which probably represents the processus vaginalis. The cyst is thin-walled and contains serous fluid. This is an example of an encysted hydrocoele of the cord.
