Abstract

Basal cell carcinomas usually arise from the epidermis and show some epidermal connections. It is very unusual that basal celi carcinomas occur as subderrnal mass without epidermal connections. A 51 year-old female h;d an asymptomatic skin colored indurated plaque with linear old scar on the left side of nose fcr about 20 years. She had had a tumor that supposed to be a epidermal cyst, on the same site and the lesion was excised about 20 years ago. We performed the punch biopsy on her first visit which revealed hypertrophic scar. She was treated with intralesional injection of triamcinolone acetonide to reduce the size of hypertrophic scar. However, the lesion had not been reduced. She underwent the surgery to remove the scar at plastic surgery and the excisional biopsy showed a subdermal basal cell carcinoma. We recommend that the newly developed skin tumor in the pre-excised region should be required excisional biopsy instead of punch and close observation
