Abstract

Basaloid squamous carcinoma is a rare distinct histologic variant of squamous cell carcinoma of the head and neck region. Basaloid squamous carcinoma is more aggressive and has a poorer prognosis, although histologically, it is associated with squamous cell carcinoma and squamous atypia. The usual site of occurrence for basaloid squamous carcinoma is the base of the tongue, hypopharynx (pyriform sinus), and the supraglottic larynx (Wain et al. Hum Pathol 1986;17:1158-1166). We are reporting an unusual case of basaloid squmous carcinoma of the mandible with no secondaries and features of sarcomatoid pattern histologically.

摘要

基底样鳞状细胞癌是头颈部区域鳞状细胞癌中一种罕见的独特组织学变体。基底样鳞状细胞癌侵袭性更强，预后更差，尽管在组织学上它与鳞状细胞癌及鳞状异型性相关。基底样鳞状细胞癌的常见发生部位是舌根、下咽（梨状窦）和声门上喉（温等人，《人类病理学》1986年；17:1158 - 1166）。我们报告一例罕见的下颌骨基底样鳞状细胞癌病例，无转移，且在组织学上具有肉瘤样模式特征。
