Cervical polyps

Cervical polyps are common entities that can be bothersome and are thus removed by a gynecologist. The vast majority are benign.

Benign endocervical polyp

Endocervical polyp redirects here.

General

• Usually 30-50 years old.
• May cause bleeding.

Microscopic

Features:

• May have mixed epithelium, i.e. squamous and endocervical type (with eosinophilic mucin).
  • Endocervical epithelium should have nuclei like that in the colon, i.e. small, round & basal.
• Polypoid shape.
• +/-Inflammation.
• +/-Squamous metaplasia.

Negatives:

• No mitoses.
• No nuclear atypia.
• No stromal proliferation.

Notes:

• No histologic features separate cervical polyps from benign endocervical mucosa; ergo, they are often signed-out as "... consistent with cervical polyp."

DDx:

• Benign endometrial polyp.
• Fibroepithelial stromal polyp.
• Adenosarcoma.
• Papillary adenofibroma of the uterine cervix.

CERVICAL POLYP, EXCISION:
- CONSISTENT WITH BENIGN ENDOCERVICAL POLYP WITH AN EROSION AND INFLAMATION.
- NEGATIVE FOR MALIGNANCY.

Papillary adenofibroma of the uterine cervix

• AKA cervical papillary adenofibroma.

General

• Rare.

Clinical:

• • • Polypoid lesions.
    • Squamous epithelium.
    • Variable cellularity.
    • Multinucleated cells.

Pseudosarcomatous fibroepithelial stromal polyp

General

• Uncommon.
• Wide age range.
• May be misdiagnosed as a sarcoma and overtreated.
• Similar lesions in vagina and vulva.

Microscopic

Features:

• Hypercellularity.
• Marked nuclear pleomorphism (common).
• +/-High mitotic rate ( > 10 mitoses / 10 HPF).
• +/-Atypical mitoses.
• No identifiable margin between lesion and normal - important feature.
• Scattered multinucleated stromal cells - usu. close to epithelium.

DDx:

• Adenosarcoma.

IHC

• Desmin +ve (common).
• SMA usu. -ve.
