A Case of Superficial Giant Basal Cell Carcinoma with Satellite Lesions on Scalp

Giant basal cell carcinoma (BCC), defined as a lesion greater than 5 cm at its largest diameter, is a rare variant of BCC. In contrast to small BCC, giant BCC develops on skin that is not exposed to sunlight, including the back, shoulder, groin and thigh. Most of the histopathologic subtypes of giant BCC are micronodular, morpheaform and nodular, but the superficial subtype is rare. Giant superficial BCC arising on the scalp is extremely rare. We report the case of giant superficial BCC with four satellite lesions on the scalp in a 53-year-old male without predisposing factors.
