Symposium part III: tumor-like glandular lesions of the uterine cervix.

A number of nonneoplastic glandular lesions of the uterine cervix may be misinterpreted as malignant. Familiarity with their histopathologic features is essential in their recognition and appropriate management. This discussion reviews the clinical and pathologic features of a variety of pseudoneoplastic glandular lesions of the uterine cervix, with an emphasis on those that have been recently described and those that one may encounter more commonly in practice. The entities that will be discussed include tunnel clusters, microglandular hyperplasia, mesonephric hyperplasia, endocervical glandular hyperplasia, and the Arias-Stella reaction.
