Synovial sarcoma is a malignant mesenchymal neoplasm usually involving the extremities of young adults. Localization in the head and neck region is rare. Histologically, these lesions have biphasic and monophasic variants, the latter being more rare and difficult to identify. Immunohistochemistry plays a crucial role in the diagnosis. We report a case of a biphasic synovial sarcoma arising in the hypopharynx with a review of the literature concerning this rare neoplasm.
滑膜肉瘤是一种恶性间叶性肿瘤，通常累及年轻成年人的四肢。发生于头颈部区域较为罕见。组织学上，这些病变有双相型和单相型两种变体，后者更为罕见且难以识别。免疫组织化学在诊断中起着关键作用。我们报告一例发生于下咽的双相型滑膜肉瘤病例，并对有关这种罕见肿瘤的文献进行综述。
