Abstract

An alveolar soft-part sarcoma (ASPS) occurring in the cheek is described, with a review of the literature. The subject was a 25-year-old woman who presented with a large swelling in the left cheek. The lesion, initially diagnosed as a benign tumor on radiographic and computed tomographic examinations, was surgically excised. Histopathological examination of the mass revealed a nest-like or organoid cellular arrangement as confirmed by three-dimensional computer graphic reconstruction. The cytoplasm of the large polygonal tumor cells contained abundant diastase-resistant, PAS-positive inclusions, ultrastructurally confirmed to be crystalloid materials. The tumor cells were immunoreactive for anti-myoglobin, sarcomeric actin, and neuron-specific enolase antibodies, suggesting a myogenic origin.
