[Esophageal sarcomatoid carcinoma: report of a case with morphological, immunohistochemical and molecular study]. / Carcinome sarcomatoïde de l'oesophage: à propos d'un cas avec étude immunohistochimique et moléculaire.

Sarcomatoïd carcinoma is a rare tumor of the esophagus, characterized macroscopically by a polypoid aspect and histologically by the association of spindle cell carcinoma with sarcomatous pleomorphic component. We report here a case of esophagus sarcomatoïd carcinoma. Diagnosis was based on immunohistochemical analysis of tIssue samples. Human papillomavirus (HVP) detection by PCR amplification of DNA extracted from tumoral tIssue was negative, ruling out the role of HPV infection in this tumor.
