Basaloid squamous carcinoma was initially characterized in 1986, and it has been an uncommon entity, with 86 reported cases occurring in the head and neck. Although histologically associated with squamous cell carcinoma and squamous atypia, basaloid squamous carcinoma has distinctive clinical features. It is frequently diagnosed at an advanced stage, often with distant metastases, and it may be associated with second primary tumors. This tumor most commonly occurs in the base of the tongue, hypopharynx, and larynx. We report a case of basaloid squamous carcinoma that occurred in the anterior floor of the mouth--a distinctly unusual location.
基底样鳞状细胞癌最初于1986年被描述，它是一种罕见的实体瘤，头颈部仅有86例报道。尽管在组织学上与鳞状细胞癌和鳞状上皮异型性相关，但基底样鳞状细胞癌具有独特的临床特征。它常被诊断为晚期，常伴有远处转移，并且可能与第二原发性肿瘤相关。这种肿瘤最常见于舌根、下咽和喉部。我们报告1例发生于口腔前底部的基底样鳞状细胞癌——一个明显不寻常的部位。
