Clinical features

● Endocervical polyps originate in the endocervical canal in 2-5% of women
● May be benign or contain another lesions such as dysplasia or carcinoma
● Benign polyps may be diagnosed as AGUS on cytologic smear (Acta Cytol 2000;44:41, Acta Cytol 1999;43:351)

Cytology description

● Tridimensional groups of endocervical cells, may show squamous metaplasia, hyperchromasia, mitosis and cellular crowding limited to a few groups of cells only
● Endocervical polyps are prone to ulceration that causes degenerative, reparative and metaplastic changes that can be seen on cytology; these changes may mimic dysplasia or glandular neoplasia
● Benign polyps have no feathering, no nuclear palisading, no chromatin clearing
● Rarely contains metastatic disease (Acta Cytol 1996;40:765)

Differential diagnosis

● Squamous dysplasia, glandular abnormalities
