Sarcomatoid malignant neoplasm, are extremely rare and aggressive head and neck tumours characterized by twin microscopic differentiation of epithelial cell and mesenchymal cell tumours. The clinical and histopathologic features make it difficult to distinguish sarcomatoid cancer from epithelioid sarcoma; creating a challenge for the pathologist to arrive at a diagnosis. Squamous cell carcinoma is the second most common head and neck malignancy; of which only 3% show features similar to sarcomatoid cancer. We present a case of sarcomatoid carcinoma of the maxilla. This has previously only been documented in a few case reports.
梭形细胞恶性肿瘤极其罕见，是一种侵袭性头颈部肿瘤，其特征为上皮细胞和间叶细胞肿瘤的双重微观分化。临床和组织病理学特征使得梭形细胞癌很难与上皮样肉瘤区分，这给病理学家的诊断带来了挑战。鳞状细胞癌是头颈部第二大常见恶性肿瘤，其中只有 3%表现出类似于梭形细胞癌的特征。我们报告了一例上颌骨梭形细胞癌病例。此前，这种病例仅在少数病例报告中有所记载。
