Ectomesenchymal chondromyxoid tumor (ECMT) is a rare entity of the dorsal tongue first described in 1995. Herein, we report a rare case of lingual ECMT in a 41-year-old man. Patient presented with an asymptomatic, small nodule (0.5 cm in diameter) in the anterior tongue. The pathological findings showed uni-lobular proliferation of fusiform cells, arranged in net-like sheets or swirls, in a chondromyxoid background. The tumor cells were immunoreactive for S-100 and glial fibrillary acidic protein (GFAP), but negative for epithelial markers. Familiarity with this entity helps pathologists make a correct diagnosis.
