title: Adenoid squamous carcinoma (pseudoangiosarcomatous carcinoma) of the vulva: a rare but highly aggressive variant of squamous cell carcinoma-report of a case and review of the literature.
abstract: Pseudoangiosarcomatous squamous cell carcinoma is an unusual but aggressive variant of acantholytic squamous cell carcinoma of the vulva that mimics angiosarcoma on histology. We present a case of a 57-year-old woman with bilateral inguinal metastatic disease at the time of diagnosis, who died 4 months later because of distant metastatic disease to the lungs. Molecular analysis did not reveal any human papillomavirus infection. Because of the positive p53 immunostaining and the association to lichen sclerosus and simple type of high-grade vulvar intraepithelial neoplasia, alteration of p53 tumor suppressor gene might be involved in the pathogenesis of vulvar pseudoangiosarcomatous squamous cell carcinoma. However, further molecular studies are required.
