Detection of HPV-DNA by a PCR-based method in formalin-fixed, paraffin-embedded tissue from rare endocervical carcinoma types.

High-risk human papilloma virus (HPV) seems to play a role in the pathogenesis of cervical squamous neoplasia and adenocarcinomas of the mucinous and endometrioid cell types. Cervical serous, clear cell, and small cell carcinomas differ from the conventional endocervical adenocarcinoma in their clinical characteristics. The data on the role of HPV in their pathogenesis are limited.
