Melanotic neuroectodermal tumor of infancy (MNTI) is a rare neoplasm known by a variety of names including melanotic progonoma and retinal anlage tumor, and currently thought to be neural crest derivation. The vast majority develop within the first year of life. The behavior is generally benign, but recurrent and metastatic cases have been documented. It arises in the head and neck in over 90%, mainly in the maxilla, but is extremely rare in the epididymis. We report a case of MNTI together with a review of literature, which occurred in the right epididymis of a 6-month-old boy who presented with a painless, slowly growing, scrotal mass and was treated with radical orchiectomy.

Cardiac rhabdomyoma is a rare type of benign tumor affecting the heart. There are a few previous reports of intracardiac rhabdomyomas causing ventricular arrythmia. We describe a 1-year-old female tuberous sclerosis patient who was presented with a ventricular tachycardia. Diagnostic echocardiography revealed two masses in the left ventricular outflow tract originating from the ventricular septum. The masses were surgically resected through aortotomy using cardiopulmonary bypass and the masses appeared benign. The pathology was that of a cardiac rhabdomyomas. Postoperative course was uneventful and the ventricular tachycardia was controlled.
