Alveolar Soft-Part Sarcoma

Abstract
Approximately 25% of all alveolar soft-part sarcomas have their origin in the head, where the tongue and orbit are sites of predilection. The neoplasms possess characteristic light and electron-optic features, yet their histogenesis remains unclear. Recurrences, early metastases, and lethality over a prolonged period are pertinent biologic findings.
