Abstract
Sarcomatoid carcinoma is a rare tumor with a poor prognosis, otherwise known as carcinosarcoma. Gastrointestinal origin is very rare and only a limited number of anal carcinosarcomas have been reported in the literature. The management of this rare cancer type is controversial. The aim of this case report was to confirm that by combining treatment modalities we can achieve long disease free intervals. Concomitant chemoradiotherapy led to a good partial response and this was followed by a consolidation surgical endo-anal excision.
