Giant condyloma acuminatum in a baby boy.

A giant condyloma acuminatum developed on the penis of a one and a half-year-old Japanese boy in two months. The histological features of this tumor were compatible with those of ordinary condyloma acuminatum. Although we detected the presence of human papilloma virus (HPV) type 16 by using the polymerase chain reaction system, we could not rule out the possibility that this HPV was present concurrently with other HPV types that cause condyloma acuminatum. The lesion was successfully treated with cryotherapy and topical application of 5% fluorouracil ointment under occlusion.
