Abstract
A case of giant basal cell carcinoma is reported. A 61-year-old man had a 23×15cm in size ulcerous tumor, which was surrounded by a shiny black nodules, on his buttock. He didn't have visited to any hospitals for 10 years. When he came to consult us for the first time, he had severe anemia for bleeding from the tumor. The lesion was totally excised with more than 1cm margin, the defect of which was covered by a mesh skin graft. Histopathological findings showed that the tumor was nearly composed of solid type BCC, which intermingled with SCC like lesions. There was no evidence of metastasis for 22 months after operation.
