Basaloid squamous carcinoma is believed to be a histologically distinct variant of squamous cell carcinoma of the neck region with 11 cases reported. Two cases arising in the pyriform fossa and vallecula are reported, both of which were associated with second primary malignant tumors: esophageal small cell carcinoma and palatal squamous cell carcinoma, respectively. The authors suggest that basaloid squamous carcinoma may be associated with a high incidence of second primary tumors in the upper gastrointestinal tract or larynx.
基底样鳞状细胞癌被认为是颈部鳞状细胞癌在组织学上的一种独特变体，目前已报道11例。本文报道了2例发生于梨状窝和会厌谷的病例，这2例均与第二原发性恶性肿瘤相关，分别为食管小细胞癌和腭部鳞状细胞癌。作者认为，基底样鳞状细胞癌可能与上消化道或喉部第二原发性肿瘤的高发病率相关。
