An unusual presentation of an aggressive spindle cell skin cancer.

Spindle cell squamous cell carcinoma (SCSCC) is a rare subtype of squamous cell carcinoma (SCC) that was first reported around 1900. Its potential for metastasis is uncertain. There has been noted a relationship to previous exposure to radiation therapy with subsequent aggressive presentation. We report an unusual case of a widely metastatic, poorly differentiated cutaneous spindle cell neoplasm with a rapidly progressive clinical course and dismal outcome in several days. This is one of a very few cases in the literature in which a skin cancer recurs with such diffuse metastasis and disastrous outcome.
