Abstract:
Teratomas rarely present as a pediatric congenital primary penile mass. We describe a 14-month-old boy with a blister-like mass on his distal left penis. The subcutaneous mass measured 1.5 cm (length)×1.0 cm (width)×1.2 cm (height) on ultrasonography. There were clear margins between these structures and the lesion. At the age of 5 years, he received an extirpation surgery. Histologic analysis revealed that it was a mature teratoma. In our view, surgical resection should be the treatment of choice for a pediatric penile mass with the alertness of teratomas because of the possibility of malignant alteration and invasion of adjacent structures till unresectable.
