A very rare case of enteric-type villoglandular papillary adenocarcinoma of the uterine cervix associated with in situ squamous cell carcinoma in a 21-year-old nulliparous caucasian woman is reported. Adjacent to the infiltrative component of an enteric-type lesion, cervical intraepithelial glandular neoplasia (CIGN) was also noticed. Histochemical detection of acetylated sialomucins demonstrates the enteric-type nature of this neoplastic (via metaplasia) process. The patient was treated by conization. Follow-up was uneventful one year after diagnosis.
