An example of the use of quantitation in histological diagnosis by a comparison of normal human cheek mucosa and cheek mucosa affected by lichen planus

Abstract
As an example of the use of quantitation in histological diagnosis the features of normal human check mucosa (NHCM) and non‐ulcerative lichen planus of the check mucosa (LPCM) have been systematically studied and quantified in order to establish normal an pathological features which arc constant. The technique enabled the quantitative verification of previously held concepts relating to NHCM and LPCM. A number of interesting features which have been given little attention in past literature we e also noted. It is proposed that a reliable quantifiable range of characteristic histological features should be established for use in diagnosis where possible rather than relying on the subjective approach currently employed.
