Pseudovascular adenoid squamous cell carcinoma (PASCC) is an uncommon histological variant of squamous cell carcinoma that can mimic vascular neoplasms, particularly angiosarcoma, in its morphologic characteristics. PASCC has been reported in the head and neck, as well as in the other organs such as the breast, lungs, urinary bladder, vulva, and uterine cervix. Only two cases of PASCC arising from the upper aerodigestive tract have been reported so far. We report a case of PASCC of oral cavity in a 40-year-old man, which mimicked an angiosarcoma initially. Immunohistochemical analysis led to a conclusive diagnosis of PASCC.
假血管腺样鳞状细胞癌（PASCC）是鳞状细胞癌一种罕见的组织学变异型，其形态学特征可类似于血管肿瘤，尤其是血管肉瘤。PASCC已报道于头颈部，以及其他器官，如乳腺、肺、膀胱、外阴和子宫颈。迄今为止，仅报道了2例起源于上消化道的PASCC。我们报告1例40岁男性口腔PASCC，最初表现类似血管肉瘤。免疫组织化学分析最终确诊为PASCC。
