[Epithelioid sarcoma. Apropos of 2 cases. Immunohistochemical study and review of the literature]. / Sarcome épithélioïde. A propos de deux observations. Etude immuno-histochimique et revue de la littérature.

We report two cases of epithelioid sarcoma (ES), including one with a 32-year follow-up. Difficult diagnostic problems often arise in this infrequent form of soft tissue sarcoma that predominantly involves the extremities and usually affects young individuals. Immunohistochemistry cannot elucidate histogenesis but does provide helpful information for the differential diagnosis.
