Epithelioid sarcoma involving sciatic nerve with lung metastasis and local recurrence: A case report

Abstract

Involvement of a deep peripheral nerve by epithelioid sarcoma (ES) is extremely rare, especially in sciatic nerve. It is a highly aggressive malignant tumor with poor prognosis and comparatively difficult to detect and confirm diagnosis in early stage. We report a rare case of epithelioid sarcoma involved the sciatic nerve which presented with chronic sciatic pain and treated with radically wide resection, but lung metastasis and local recurrence have occurred shortly after surgical resection and resulting in the patient's death in six months after initial presentation.
