Epithelioid sarcoma metastasis to the gingivae: a case report.
We present a rare case of oral metastatic epithelioid sarcoma rapidly growing over the mandibular gingivae; the primary lesion occurred on the wrist and was treated 18 months earlier by surgery and radiotherapy. The oral metastatic lesion was resected and controlled by chemotherapy. This case has been followed for 2 years with good control of the resected oral metastatic lesion. Histologically, round to oval-shaped tumour cells with abundant eosinophylic globular cytoplasm and eccentrically localized nuclei, lack of epithelial features by electron microscopic study, and the immunohistochemical and cytologic features of tumour cells led into the diagnosis of epithelioid sarcoma. To our knowledge, no reports have been published of its occurrence in the oral cavity
