Dermoscopy of palmoplantar keratoderma: development and analysis methods

Abstract

Palmoplantar keratoderma (KPP) is a group of inherited or acquired conditions characterized by palmar and plantar hyperkeratosis. The analysis can be difficult, however, thanks to dermoscopy, which is a non-invasive means of exploration, certain signs are very orienting for the right diagnosis. The available data concerning the dermoscopic profile of palmoplanar pathologies are still limited in the literature. we have reviewed the dermoscopic signs of KPP which target the acquired inflammatory dermatoses frequently found in the routine consultation of the dermatologist. The aim is to realize a dermoscopic guide for the dermatologist in front of KPP and to facilitate the diagnostic orientation in front of this topography using the Dermoscope. We have illustrated with dermoscopic images taken from patients followed in consultation.The analyzed images were taken with minimal pressure to preserve vessel morphology, and immersion with a clear, thick, colorless gel to ensure better visualization.
