Key Points

  • The aim is to evaluate a simple technique that enhances the diagnosis of nodular basal cell carcinoma.
  • Observation of the rubbing technique in clinical settings
  • Assessment of its effect on the visualization of nBCC features like arborizing vessels
  • Comparison of diagnosis accuracy with and without the technique
  • The technique enhanced visibility of arborizing vessels and erosions, aiding in diagnosis
  • Potential reduction in unnecessary biopsies was noted
  • The technique may help preserve cosmetic outcomes for patients

Abstract

Nodular basal cell carcinoma (nBCC) of the face can be challenging to diagnose in its early stages. We report our observation of a simple and rapid clinical maneuver that enhances the visualization of arborizing vessels, erosions, and bleeding, thereby facilitating the identification of nBCC. This preliminary observation suggests that the technique may reduce unnecessary biopsies, preserve cosmetic outcomes, and support timelier patient management.
