“…Clinically, blue vitiligo should be distinguished from blue naevus with overlying vitiligo, as depigmented patches and blue macules can be found in lesions of both conditions. In the former, depigmented patches appear first, followed by the presence of blue macules within the lesions, whereas with the latter, the blue macules are already existing when the depigmented patches develop.…”

A 23-year-old Chinese man presented with a 16-month history of white patches on his abdomen and neck. He had previously received an intralesional injection of psoralen along with narrowband psoralen ultraviolet B radiation (PUVB) therapy. Blue macules had appeared in and around the injection sites 1 week later. Dermoscopy revealed blue spots and reticular telangiectasia within the white patches. Histological examination revealed an absence of epidermal melanocytes and pigment in the basal layer, as well as deposition of melanophages between collagen bundles or surrounding blood vessels and appendages in the middle and lower parts of the dermis. A diagnosis of blue vitiligo was made. The blue colour faded gradually over time. Our case provides direct evidence to support the previous surmise that PUVB can contribute to blue vitiligo. To our knowledge, this is only the fourth reported case of blue vitiligo in the English literature.

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.
