“…The aggregation of melanocytes around appendages and neurovascular bundles is also commonly seen in BN. In our case, we found diffuse dermal melanocytosis, without the characteristic dendritic melanocytes of a single BN, within the dermis, which is consistent with findings reported in some of the previous cases of ABN …”

Blue nevi are common skin neoplasms that typically present as asymptomatic solitary papules, although they may rarely occur in an agminated configuration. We describe a case of agminated blue nevus in a segmental facial distribution associated with soft tissue hypertrophy and hypertrichosis in a 16-year-old boy and present a review of the literature. Although they are generally considered to be benign, concurrent soft tissue changes occurring within an agminated blue nevus should be investigated thoroughly to exclude alternate diagnoses.

“…Upshaw and colleagues reported the first case of a PTBN on the thorax of a 9‐year‐old boy . ABN can be congenital or acquired and affect male and female individuals equally . Our case followed a benign course, which is consistent with 24 of the 26 cases that have been documented since 1990 (Table ).…”

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.
