During the recent period, dermoscopy has yielded improvement in the early disclosure of various @entity5 ( @entity5 ) of the skin. Beyond this clinical procedure, @entity5 histopathology remains mandatory for establishing their precise diagnosis. Of note, panels of experts in @entity5 merely report moderate agreement in various puzzling cases. Divergences in opinion and misdiagnosis are likely increased when histopathological criteria are not fine-tuned and when facing a diversity of @entity5 types. Furthermore, some @entity5 have been differently named in the literature including atypical @entity5 , metastasizing @entity5 , borderline and intermediate @entity5 , malignant @entity27897 , @entity2118 or @entity320 . Some acronyms have been further suggested such as MELTUMP (after @entity5 of uncertain malignant potential) and STUMP (after @entity5 of uncertain malignant potential). In this review, such @entity5 at the exclusion of @entity320 ( @entity320 ) variants, are grouped under the tentative @entity272 . Such set of @entity5 frequently follows an indolent course, although they exhibit atypical and sometimes worrisome patterns or cytological atypia. Rare cases of skin melanocytomas progress to loco regional clusters of lesions (agminate melanocytomas), and even to regional lymph nodes. At times, the distinction between a skin melanocytoma and @entity320 remains puzzling. However, multipronged immunohistochemistry and emerging molecular biology help profiling any @entity5 risk if present.
