Multiple basal cell carcinoma associated with keratoacanthoma

We report a case of multiple basal cell carcinoma associated with keratoacanthoma. A 65-year-old Korean female had suffered from multiple, variable-sized papules and nodules on the face for 20 years previous to treatment. She had no history of arsenic intake, irradiation, herb medication, or hereditable or preexisting dermatoses. Histopathologically, the tumors revealed typical findings of solid and adenoid types of basal cell carcinoma and keratoacanthoma.
