DefinitionThis section has been translated automatically.
Palmo-plantar located nevus. It has a special position, because the clinic is often difficult to distinguish from a malignant melanoma.
Clinical featuresThis section has been translated automatically.
Light brown to dark brown colored, usually blurred, with filiform runners reaching into the groin structures, spots, plaques or papules.
HistologyThis section has been translated automatically.
Melanocytic nevus of the junctional or compound type. Detection of individual melanocytes, mostly formed in nests, in the area of the junctional zone and the entire surface epithelium. Typical is the release of melanin and melanocytes into the higher epithelial layers and into the str. corneum. The dermal tumor colonization is generally low. Melanocytes show clear "maturation" downwards. No mitoses!
