Abstract
A 19-year-old female patient had had a verrucous lesion protruding below her left knee since childhood. Although she had received cryosurgery several times at a local hospital, the lesion continued to enlarge gradually. She visited our hospital for a more precise diagnosis and treatment. Skin biopsy revealed a syringocystadenoma papilliferum. The patient underwent total resection of the tumor, after which no recurrence has been observed within one year. SCAP is a predilection for apocrine gland tumors of the head and neck, mostly in young people. Reports are infrequent other than for the head and neck.Skin Research, 10: 295-297, 2011
