Extraskeletal Ewing's sarcoma of the parapharyngeal space.
Extraskeletal Ewing's sarcoma (EES) is rarely found in the head and neck region. We report here a case of EES of the parapharyngeal space in a 53-year-old man who presented with blurred vision, dysphagia, hoarseness and right facial numbness. CT examination showed a large, seemingly well-defined soft tissue mass in the right parapharyngeal space with skull base destruction and intracranial extension. The patient showed poor response to chemotherapy and radiotherapy and died 6 months after initial presentation. A review of the literature revealed no previous reports of EES occurring in the parapharyngeal space.
