Basaloid squamous cell carcinoma (BSCC) is rare. We report a case of BSCC in a 60-year-old woman who presented with a bleeding vascular growth on the left pinna. To the best of our knowledge, no case of BSCC of the pinna has been previously reported in the literature. We present this case to alert physicians that this highly aggressive variant of squamous cell carcinoma can appear on the pinna and therefore it should be considered in the differential diagnosis of lesions in this area.
Basaloid squamous cell carcinoma (BSCC) is a rare, histologically distinctive, highly aggressive variant of squamous cell carcinoma.1,2 BSCC primarily affects men in the sixth and seventh decades of life.2 Affected patients usually present with advanced-stage disease and widespread metastases.
