A case is reported of diffuse laminar endocervical glandular hyperplasia, which is very rare among pseudoneoplastic endocervical glandular lesions. The patient was a 54 year old woman who had been suffering from watery vaginal discharge for about 7 years, and the lesion was found in the cervix of the hysterectomy specimen. Microscopically, the lesion showed a diffuse, laminar proliferation of hyperplastic endocervical glands, sharply demarcated from the underlying stroma. The significant nuclear atypia was absent. Inflammatory response was mild. Immunohistochemically, carcinoembryonic antigen was negative. Differential diagnosis from other non-neoplastic conditions and well differentiated adenocarcinoma is discussed.
