    Abstract:
    To clarify the pathogenesis of cervical adenocarcinoma, we studied the biological properties of glandular dysplasia (GD). The coexistence of squamous neoplasia with cervical adenocarcinoma has been demonstrated. We analyzed the incidence of the coexistence of GD with squamous neoplasia in this study. Materials were surgically removed uterine cervix specimens (n = 142), 52 benign disease cases, 19 squamous dysplasias of the uterine cervix, 66 squamous cell carcinomas of the uterine cervix and 5 cervical adenocarcinomas. Diagnosis of GD was based on the general rules for clinical and pathological management of uterine cervical cancer and Ng's criteria (1983). We divided GD into two types: I: endocervical type, and II: endometrioid type. These fell into subtypes, a (mild) and b (severe) based on the observed degrees of cell atypia. 1. GD coexisted in 17.3% of benign disease cases, 15.8% of squamous dysplasias, 24.2% of squamous cell carcinomas and 100% of cervical adenocarcinomas. 2. GD Ib and IIb were not found in any of the benign disease cases, but were present in 15.8% of squamous dysplasias, 13.6% of squamous cell carcinomas and 100% of cervical adenocarcinomas. If GD was defined as only Ib and IIb, GD coexisted with squamous neoplasia in this study. Our results support the theory that both cervical squamous atypia and cervical glandular atypia are derived from reserve cells.
