Nodular Basal Cell Carcinoma Arising in a Split-Thickness Skin Graft of the Scalp

We present the first known case of basal cell carcinoma arising in a split-thickness skin graft in the United States. The apparent low incidence of basal cell carcinoma in split-thickness skin graft attests to its unique environment and could possibly be attributed to the following: (1) the donor sites for split-thickness skin grafts are usually areas that are not subjected to heavy sun exposure; (2) individuals with skin grafts may not live as long on average, or their skin grafts may be subsequently excised with further reconstructive procedures; and (3) cases may be underreported. Because basal cell carcinomas have a fairly benign course, many patients either do not present to a physician or are not reported. This case shows that a split-thickness skin graft can have an adequate microenvironment for the development of basal cell carcinoma.
