title: Pseudovascular adenoid squamous cell carcinoma of oral cavity: A mimicker of angiosarcoma.
abstract: 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.
