[Synovial sarcoma of the tongue. Case report and review of the literature].
Primary synovial sarcoma of the head and neck is a rare entity, nevertheless the literature count on 80 published cases, among them 7 linguals. We contribute with another case: a synovial sarcoma of the tongue, in a 26-year-old man; having a biphasic tumor pattern, with two malignant constituents, epithelial and sarcomatous, similar to other of the same location. Laboratory tests: histochemical, immunohistochemical and electron microscopic were done in order to state the tumor's histogenesis. Our results suggest a pluripotential mesenchymal origin instead of a synovial origin, because the epithelial character of one of the tumor constituents was obviously epithelial.
