title: Basaloid squamous cell carcinoma of the external auditory canal: case report.
abstract: Basaloid squamous cell carcinoma (BSCC) is a rare malignancy, with features of both basal cell carcinoma and squamous cell carcinoma. The tumor has a predilection for the upper aerodigestive tract, and has been suggested to behave more aggressively than squamous cell carcinoma (SCC). To the author's knowledge, BSCC confined to the external auditory canal (EAC) has not been previously described. BSCC of EAC manifests similar characteristics as the conventional EAC cancer, presenting a mass with chronic otorrhea and itching sense. Excision of the tumor was accomplished by modified lateral temporal bone resection. This report describes the first case of BSCC in this location, and includes reviews of the pathologic and clinical aspects of this disease.
