Adenoma (Mucous Polyp)Clinical Features
– Asymptomatic– Vaginal discharge– Vaginal bleeding– Mass at the introitus
Differential Diagnosis– Carcinoma of the cervix– Cervical ectopy– Endometrial polyp– Products of conception
and blood clot– Ectropion– Cervical tags

Adenoma (Mucous Polyp)
Treatment– Asymptomatic must be removed and
examined by the histopathologist– Adenoma may be avulsed easily without
anaesthesia– Base of the polyp should be cauterized
to avoid recurrence– Perform curettage

Cervical Intraepithelial Neoplasia (CIN)
or Dysplasia• Spectrum of disordered growth and
abnormal microscopic changes confined to epithelium
• May be– Mild (CIN I)– Moderate (CIN II) – Severe or carcinoma in situ (CIN III)
• Spontaneous regression of mild and moderate types possible
• Severe dysplasia may be irreversible• May progress into invasive carcinoma

Cervical Intraepithelial Neoplasia (CIN)
or Dysplasia•CIN I (mild)
Involves deeper 3rd of epithelium
•CIN II (moderate)Involves more than half thickness of epithelium
•CIN III (severe)Whole thickness of epithelium shows abnormal changes

Case Historybiopsy showed invasive nests of abnormal squamous epithelium extending under the surface mucosa, extending all the way through the cervical wall and out into the surrounding paracervical soft tissue
