[A case of soft tissue alveolar sarcoma localized in the tongue].

Alveolar soft-part sarcoma is a rare form of malignant tumour. It is generally localized at the limb muscles, rarely in the head and neck. Its histogenesis is still uncertain but its specific cellular characters make the diagnosis easier. The case of a woman with an ASPS of the tongue is described. The morphological aspects and the immunohistochemical results seem, according to the data reported in literature, suitable with the diagnosis of alveolar soft-part sarcoma; however, it is difficult to explain the presence of local positivity to specific neuronal enolase.
