Abstract
Diascopy is a fundamental clinical examination technique for
differentiating vascular from pigmented oral lesions by applying external
pressure to assess tissue blanching characteristics. This noninvasive chairside
procedure is particularly useful for diagnosing hemangiomas, varicosities, and
pyogenic granulomas and for excluding melanotic lesions. This technique appears
in some of the published diagnostic algorithms for oral pigmented lesions.
Despite its diagnostic value and accessibility, diascopy has limitations,
including operator dependence, variable effectiveness for deep-seated lesions,
and insufficient specificity as a standalone diagnostic tool. Therefore, it
must be integrated with comprehensive clinical examination and
histopathological confirmation for a definitive diagnosis.
