2001 Bethesda System Terminology

Specimen Type: Indicate conventional smear (Pap smear) vs. liquid based vs. other

Specimen Adequacy

  • Satisfactory for evaluation (describe presence or absence of endocervical/transformation zone component and any other quality indicators, e.g., partially obscuring blood, inflammation, etc.)
  • Unsatisfactory for evaluation … (specify reason)

*Specimen rejected/not processed (specify reason)
*Specimen processed and examined, but unsatisfactory for evaluation of epithelial abnormality because of (specify reason)

General Categorization (optional)

  • Negative for intraepithelial lesion or malignancy
  • Epithelial cell abnormality: See interpretation/result (specify ‘squamous’ or ‘glandular’ as appropriate)
  • Other: See interpretation/result (e.g. endometrial cells in a woman > 40 years of age)

Automated Review

If case examined by automated device, specify device and result.

Ancillary Testing

Provide a brief description of the test methods and report the result so that it is easily understood by the clinician.

Interpretation/Result

Negative for Intraepithelial Lesion or Malignancy (when there is no cellular evidence of neoplasia, state this in the General Categorization above and/or in the Interpretation/Result section of the report, whether or not there are organisms or other non-neoplastic findings)

Organisms:

  • Trichomonas vaginalis
  • Fungal organisms 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

Other non neoplastic findings (Optional to report; list not inclusive):

  • Reactive cellular changes associated with

*inflammation (includes typical repair)
*radiation
*intrauterine contraceptive device (IUD)

  • Glandular cells status post hysterectomy
  • Atrophy

Other

  • Endometrial cells (in a woman > 40 years of age)

(Specify if ‘negative for squamous intraepithelial lesion’)

Epithelial Cell Abnormalities

SQUAMOUS CELL

  • Atypical squamous cells (ASC)

*of undetermined significance (ASC-US)
*cannot exclude HSIL (ASC-H)

  • Low grade squamous intraepithelial lesion (LSIL)

*encompassing: HPV/mild dysplasia/cervical intraepithelial neoplasia (CIN) 1

  • High grade squamous intraepithelial lesion (HSIL)

*encompassing: moderate and severe dysplasia, carcinoma in situ (CIS)/CIN 2 and CIN 3

*with features suspicious for invasion (if invasion is suspected)

  • Squamous cell carcinoma

GLANDULAR CELL

  • Atypical

*endocervical cells (NOS or specify in comments)
*endometrial cells (NOS or specify in comments)
*glandular cells (NOS or specify in comments)

  • Atypical

*endocervical cells, favor neoplastic
*glandular cells, favor neoplastic

  • Endocervical adenocarcinoma in situ (AIS)
  • Adenocarcinoma

*endocervical
*endometrial
*extrauterine
*not otherwise specified (NOS)

Other Malignant Neoplasms: (specify)

Educational Notes and Suggestions (optional)
Suggestions should be concise and consistent with clinical follow-up guidelines published by professional organizations (references to relevant publications may be included).
