Sažetak
Ectomesenchymal chondromyxoid tumor of the tongue was first described as an entity in 1995. To date, only 27 cases have been reported in the literature. Clinically, this benign neoplasm presents as a solid, painless, slowly growing mass that typically involves the anterior dorsal tongue. We report an additional case. We present a case of a 53-year-old female patient with a solid, slowly growing, painless mass on the anterior dorsal tongue that had appeared 2 months before. A segment of the tongue with a mildly elevated tumor of yellowish solid cut surface, measuring 0.8 cm in diameter, was excised and referred for histopathologic analysis. Microscopically, the tumor was well-circumscribed, non-encapsulated, composed of lobules containing ovoid and round to polygonal cells, with small nuclei and mildly basophilic cytoplasm, set in a chondromyxoid background. The tumor cells were immunoreactive to GFAP, focally reactive to SMA and S-100 protein, and non-reactive to EMA, cytokeratin and CD 34. Ectomesenchymal chondromyxoid tumor of the tongue is a tumor that fails to meet the established clinicopathologic criteria for any existing myxoid neoplasm of the tongue, including nerve sheath myxoma, myoepithelioma, ossifying fibromyxoid tumor of soft parts, extraskeletal myxoid chondrosarcoma, chondroid choriostomas or heterotopias. There are no clinical features that may distinguish it from the above mentioned neoplasms. Therefore, the diagnosis can be only established by means of histology and immunohistochemistry.
