medical Definition of ASCUS

atypical squamous cells of undetermined significance
Note: ASCUS is a diagnosis used in cytology to describe the presence of abnormal squamous cells in a Pap smear test. Upon staining, these cells exhibit an atypical appearance (as enlarged nuclei or irregular shape) that cannot definitively be classified as benign or precancerous.
  • Many physicians believe that combining the Pap test with direct virus testing may prove particularly useful when a pap test comes back with its most common indeterminate result, called ASCUS—atypical squamous cells of undetermined significance.
  • —Jerome GroopmanThe New Yorker13 Sept. 1999
  • Currently, there is no consensus on what to do with ASCUS patients, only 5% to 10% of whom actually have precancerous cells.
