Glandular lesions of the uterine cervix: the present state of our knowledge

The assessment of squamous lesions of the uterine cervix is a major preoccupation of diagnostic histopathologists and this can overshadow the recognition of significant abnormalities affecting the adjacent endocervical glands. This review gives an account of recent advances in our knowledge of the histology and histochemistry of endocervical glands. The review of benign lesions concentrates on those that continue to cause diagnostic difficulty. Adenocarcinoma in situ, lesser degrees of possibly pre-malignant cervical glandular atypia and histological subtypes of adenocarcinoma are outlined. The increasing awareness that glandular and squamous lesions often co-exist is emphasized. Finally, adenocarcinoma metastatic to the cervix is discussed.
