Abstract

A 31 year-old-woman, who was born with spina bifida, club foot, hemiagenesis, and dysfunction of urinary bladder and rectum. She found the subcutaneous tumor of left inguinal region about 6 months before her visit. The tumor had enlarged rapidly, and become painful, then she visited the orthopedics. Since needle biopsy suggested a metastasis of melanoma, she was introduced to our hospital. At this time, ulcerative and erosive red huge tumor (8cm across and 4cm high) with subcutaneous induration beneath the tumor was found at left inguinal region. A small verrucus tumor was found in the strongly keratinized callus on the left sole. The biopsied specimens from the tumor showed the findings of amelanotic melanoma. <BR>This case suggests that chronic trauma is one of the causative factors of acral lentiginous melanoma.
