男児尿道口に発生した尖圭コンジローマの1例

Abstract

A 4-year-old boy was referred for treatment of papillary tumor at the urethral meatus. He was well until December 1990, when his mother noticed a tumor at the urethral meatus. The tumor was resected elsewhere. However, a similar tumor was noted again at the urethral meatus in May, 1991. The patient was admitted on September 16, 1991. Retraction of the phimotic foreskin revealed a well-demarcated papillary mass, approximately 2 x 2 mm in diameter, at the urethral meatus. There were no tumors on foreskin or glans. Under general anesthesia endoscopy was performed to locate other tumors at the urethra and bladder. No tumors were found elsewhere. Then the meatal tumor was resected surgically. Pathology was condyloma acuminatum. There was no recurrence one year after surgery. We also reviewed 24 boys with condyloma acuminatum, including 13 boys with a solitary condyloma at the urethral meatus, reported in Japan.
