Alveolar soft-part sarcoma of the tongue. Report of a case with electron microscopic study.
Light and electron microscopic findings of a case of alveolar soft-part sarcoma of the tongue in an 11-year-old girl are reported. Diastase-resistant PAS-positive material was seen by light microscopy, while granules and crystals were observed by electron microscopy. Occasionally, some granules demonstrated a quasi-crystalline structure.
