Abstract
Basosquamous cell carcinoma (BSCC) is a rare malignant skin tumor, with histological features of both basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). It is difficult to diagnose BSCC before surgery. The recurrence rate of BSCC after surgery is high, since the surgical margin frequently shows the features of BCC.
We present a case of BSCC originating in the auricle. The patient was diagnosed as having BCC invading the cartilage before the operation. We performed an operation indicated for invasive carcinoma. At present, 2 years since the operation, the patient remains alive and without disease.
