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.
Erythema migrans necrolytica is a red, blistering rash that spreads over the skin. It particularly affects the skin around the mouth and distal extremities, but can also be found on the lower abdomen, buttocks, perineum and groin. It is strongly associated with glucagonoma, a glucagon-producing tumor of the pancreas, but is also seen in a number of other conditions, including liver disease and intestinal malabsorption such as celiac disease. We present a case of a patient with a history of poorly followed celiac disease presenting with a clinical picture of ENM. This rare case adds to our understanding of the clinical presentation of NME, as well as highlights the importance of acting in a timely manner to avoid the most redoubtful complications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
