Abstract

We reported a cace of a 61-year-old man with squamous cell carcinoma (SCC) on the external ear, which metastasized to the parotid lymph node, although the tumor was 2cm in diameter at an elrly stage. During past 10 years, we have experienced 13 patients with SCC on the external ear. All patients were male with a mean age of 76.8 years. The tumor were located mostly on the helix. Two patients developed lymph nodes metastasis, but no distal metastasis. SCC of the external ear is an aggressive cancer with higher metasiatic rates than cutaneous SCC as seen in other parts of the body. Poor prognotic facters included specific growth pattern and perineural invasion.
