WHO Classification of Tumours
Mucinous adenocarcinoma, endocervical type
Cervix uteri


Endocervical mucinous adenocarcinoma is a variant of mucinous adenocarcinoma characterized by malignant glandular cells that resemble those of the endocervical epithelium and are arranged in complex patterns. The cells are typically stratified with basal nuclei and abundant granular cytoplasm and show considerable nuclear atypia. Mitoses are frequent.
70% of cervical adenocarcinomas are of the endocervical type. Co-existent cervical intraepithelial neoplasia (CIN) is a frequent finding; adenocarcinoma in situ is also common. Synchronous mucinous tumours may occur elsewhere in the female genital tract
