The Bethesda System recommends Pap smear diagnosis to be based on the most abnormal cells present, regardless of number. Our reporting system includes a diagnostic category of mild‐to‐moderate dysplasia (D1‐2), defined as cases with only a few moderately dysplastic cells. We evaluated the validity of a D1‐2 diagnostic category by reevaluation of 58 cases with subsequent follow‐up (up to 24 months). On biopsy and/or Pap smear follow‐up, 24 cases (41%) showed LSIL and 34 cases (59%) showed HSIL. Index smears from these cases were examined by two cytopathologists blinded to patient follow‐up for the following morphologic features: volumes (scale 1–4) of LSIL, HSIL, and dyskeratosis, HSIL as single cells or syncytial fragments, and acute inflammation. None of the morphologic features evaluated were significantly different between the LSIL and HSIL follow‐up groups based on univariate and multivariate logistic regression analysis. The diagnosis of D1‐2 on Pap smear is a valid diagnostic category that defines a subgroup of patients with both LSIL and HSIL follow‐up, which cannot be reliably predicted based on morphology alone.
