title: [Epithelioid sarcoma. Apropos of 3 cases].
abstract: The authors present two cases of epithelioid sarcoma of the hand and one of the foot with clinical interest. This recently described tumor (Enzinger, 1970), is relatively rare. It occurs in the hand, forearm, pretibial region and foot and affects principally young adults. It should be emphasized, and this is borne out in the literature, that this tumor may appear perfectly benign and often has a course of long duration. The difficulty of clinical and especially of histologic diagnosis as well as the difficulty of determining the boundaries of extension of the tumor make it necessary to carry out radical surgery (amputation or rarely block excision). Every author agrees that local excision is to be condemned, there being an 85% recurrence rate. Spread of the tumor is by way of the fascial planes and tendon sheaths. Lymphatic and pulmonary metastases occur particularly when there is vascular invasion.
