Definition / general

2 - 5% of adult women
Usually multigravida age 30 - 59 years
Produces bleeding or mucoid discharge
Probably secondary to chronic inflammation and not neoplastic

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)

Case reports

5 year old girl with multilocular cystic polyp (Pediatr Pathol 1993;13:415)
33 year old woman with heterologous cartilage and adipose tissue (Pathol Int 2001;51:305)

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

Adenosarcoma

Condyloma

Polypoid adenomyoma

Superficial cervicovaginal myofibroblastoma

Squamous dysplasia, glandular abnormalities
