title: The ultrasonographic and radiologic features of a histologically proven case of alveolar soft-part sarcoma of the orbit.
abstract: An 18-year-old woman had a rapidly progressive proptosis, vascular congestion, and orbital pain. Ultrasonographic and radiologic tests supported the diagnosis of a solid vascularized mass that proved histologically to be an alveolar soft-part sarcoma of the orbit. Uncertainty as to the histogenesis of alveolar soft-part sarcoma still exists, but prognosis for patient survival is poor.
