Spindle-cell carcinoma (SPCC) is a rare tumor that presents biphasic components: squamous-cell carcinoma and sarcomatous features without any differentiation. We present a case of SPCC of the hypopharynx in a 60-year-old man. A well-demarcated mass occupying the hypomesopharynx and presenting a pedunculated appearance was observed originating from the lateral wall of left piriform sinus. High signal intensity on T2-weighted magnetic resonance (MR) images corresponded to the myxoid matrix of the tumor on MR pathologic correlation.
梭形细胞癌（SPCC）是一种罕见的肿瘤，具有双相成分：鳞状细胞癌和肉瘤样特征，没有任何分化。我们报告了一例发生于下咽的 SPCC，患者为 60 岁男性。观察到一个界限清楚的肿块占据下咽部，呈悬垂状，起源于左侧梨状窝侧壁。T2 加权磁共振（MR）图像上的高信号强度与 MR 病理相关性上肿瘤的黏液样基质相对应。
