A B S T R A C T Papillary cystadenoma of the epididymis (PCE) is the second most common benign neoplasm of the epididymis [1]. It is very uncommon and has never been reported in a prepubertal male. It may occur sporadically, but more often occurs in association with von Hippel-Lindau (VHL) disease [2].

Given the patient's history of stage IV neuroblastoma, there was suspicion of yolk sac tumor or metastases; he underwent an open radical left orchiectomy. Frozen section was consistent with yolk sac tumor, however final pathology revealed normal testicle with PCE. To date, this patient is the youngest reported patient with this diagnosis; furthermore papillary cystadenoma of the epididymis has never been reported in a patient with neuroblastoma.
