Pap Smear Interpretation and Management of Abnormals

Interpretation of Pap smear reports can be challenging at times. Unfortunately, the terminology or language of Pap smears is complex, changing, and not uniformly applied.

The following are links to explanations of different results you might see on a Pap smear. While not all-encompassing, it includes all of the common descriptive terms. I also included some of the older terminology in the event you may encounter it.

• Negative for intraepithelial lesion or malignancy

• Epithelial cell abnormality

• Other

Negative for Intraepithelial Lesion or Malignancy

• Atrophy

• Trichomonas vaginalis

• Fungal oganisms morphologically consistent with Candida species

• Shift in flora suggestive of bacterial vaginosis

• Bacteria morphologically consistent with Actinomyces species

• Cellular changes consistent with herpes simplex virus

Reactive cellular changes associated with:

• Inflammation (includes typical repair)

• Radiation

• Intrauterine contraceptive device

• Glandular cells status posthysterectomy

• Atrophy

• Atypical squamous cells (ASC) of undetermined significance (ASC-US)

• cannot exclude HSIL (ASC-H)

• Low-grade squamous intraepithelial lesion (LSIL) encompassing: human papillomavirus/mild dysplasia/cervical intraepithelial neoplasia (CIN) 1

• High-grade squamous intraepithelial lesion (HSIL) encompassing: moderate and severe dysplasia, carcinoma in situ; CIN 2 and CIN 3

• Squamous cell carcinoma

Glandular cell

• Atypical glandular cells (AGC) (specify endocervical, endometrial, or not otherwise specified)
