凍結治療をおこなった陰茎血管腫の1例

Abstract

A 16-year-old student was seen with a painless tumor on the glans penis about 9 years' duration which had not increased in size. But on penile erection, tumor became more tense and increased in size. Examination revealed a elevated, circular tumor on the dorsal portion of the glans penis of about the size of a little finger tip. Tumor was dark reddish purple in color and had a raspberry appearance. Tumor collapsed and blanched on pressure but refilled promptly when pressure was released. There was no similar lesions elsewhere on the body, and no family history of hemangiomas or no personal history of penile injury. Cavernosography revealed same distribution of dye between the corpus cavernosum and the tumor. Cryosurgery was performed. A good result was confirmed 7 months after the treatment. There was no evidence of recurrence. Reports of 16 benign penile hemangiomas, including our case, were found in the japanese literature, and briefly discussed on its etiology and therapy.
