Papillary squamous cell carcinoma
Papillary squamous cell carcinoma is a well differentiated histological variant of squamous cell carcinoma
characterized by a papillary, exophytic growth pattern. The most commonly affected anatomic sites are the larynx, penis, cervix, vagina, and vulva.
Papillary squamous cell carcinomas of the uterine cervix are positive for HPV type 16, but, in contrast to warty squamous cell carcinoma
, there are no cellular features of HPV infection. Keratinization is inconspicuous. The epithelium shows features of cervical intraepithelial neoplasia
