Ewing's sarcoma/primitive neuroectodermal tumor (ES/PNET) of the penis has been very rarely defined. We report a case of a 19-year-old patient with a tumor, localized in the dorsal side of penis, composed of small round cells with diffuse membranous mic-2 (CD99) immunopositivity. The patient was treated with multiagent chemotherapy and radiotherapy.

The authors report a rare case of imperforate anus as a congenital anomaly. Early diagnosis and close follow up are emphasized, in order to prevent the development of complications which may last for a lifetime.
