“…3 Despite the wide spectrum of their clinical appearances, DMs share common histological and immunophenotypical features with subtle differences. 2 From clinical point of view, these proliferations may be divided into two main categories: blue naevus (BN) presenting mainly with papulonodular lesions (Figs 1-4a) and other DMs presenting predominantly with patchy lesions (Figs 4b,5,6,7,8,9,10; Table 1). The latter DMs have been mainly classified according to the lesion's anatomic location: Mongolian spot (MS; lumbosacral region), naevus of Ota (trigeminal nerve area) and naevus of Ito (acromioclavicular region).…”

Dermal melanocytoses (DMs) comprise a heterogeneous group of benign lesions, located on skin and mucous membranes, characterized by dendritic melanocytes in the dermis. Although they share common histopathological features, some variants may present only as bluish or grey patches, some only as papules/nodules/plaques and others may show combination of all of these lesions. Despite the fact that blue naevus (BN) is typically characterized with papulonodular lesions, its variants may show all of the aforementioned presentations. Mongolian spot, naevus of Ota and naevus of Ito are patchy DMs distinguished by their specific localizations. Apart from these classical forms, many atypical variants without unique clinicopathological characteristics have been described in the literature making the nomenclature of DMs more complicated. However, congenital dermal melanocytosis and acquired dermal melanocytosis seem to be crucial umbrella terms that encompass all patchy DMs in atypical locations. Papules or subcutaneous nodules on patchy lesions and association of epidermal pigmentation presenting as brownish patches may be encountered as rare features of DMs. On the other hand, delayed‐onset subcutaneous nodules may be typical presentations of melanoma in patchy DMs; therefore, they deserve special attention. Large plaque‐type BN with subcutaneous cellular nodules is a newly described entity, harbouring clinical features of various DMs together and has a high risk of melanoma. The whole spectrum of dermal dendritic melanocytic proliferations is discussed including novelties and controversial issues.

“…Their immunohistochemical results showed Mel‐5 positivity as a strong marker of the melanocytic nature of these lesions, while there was weak or absent expression of anti‐S‐100 and anti‐HMB‐45 antibodies focally 1 . However, other reports found HMB‐45 antibodies to be a reliable indicator of amelanotic blue nevi but noted mixed expression of S‐100 and MART‐1 2,4‐7 . Blue nevi have been associated with somatic activating mutations in GNAQ and, to a lesser extent, GNA11 , though molecular analysis is not necessary to confirm the diagnosis 8 …”

“…Dermoscopy showed a homogeneous white background with peripheral arborizing vessels; this pattern has not been described previously. Some atypical forms of dermatofibromas [ 6 ], late stages of sclerotic dermatofibromas and amelanotic blue nevi, may occasionally present with similar dermoscopic features [ 7 ]. A sclerotic fibroma-like dermatofibroma has also been described as an uncommon variant of dermatofibroma [ 8 ].…”
