Although basal cell carcinoma (BCC) overall is less aggressive than other forms of skin cancer, the morpheaform subtype is particularly concerning because of its benign appearance and aggressive subclinical spread. We sought to evaluate risk factors for its development on the face or ears in a high-risk population of veterans with at least 2 prior keratinocyte carcinomas in the Veterans Affairs Topical Tretinoin Chemoprevention (VATTC) Trial.
