“…Dermoscopy Dermoscopic patterns of combined nevi have been described only in a small series of 21 cases including 17 cases of blue nevus associated with a dermal and/or compound nevus, two cases of blue nevus with a Clark nevus, one SN combined with a Clark nevus and one SN associated with a congenital nevus. [10][11][12][13] Because of the presence of two nevus cell populations, colour variegations or more than one structure, depending on the nevus types, are often present. The most classic type (blue nevus associated with compound or dermal nevus) is characterized by a delicate peripheral reticular pattern and/or globular pattern, respectively, and a central structureless blue pigmentation ( Fig.…”

Histopathology is considered the 'gold' standard for the diagnosis and classification of melanocytic nevi, but the widespread use of in vivo diagnostic technologies such as dermoscopy and reflectance confocal microscopy (RCM), has enriched profoundly the knowledge regarding the morphological variability in nevi. This is because most morphological observations made via these in vivo tools are closely correlated with features seen in histopathology. Dermoscopy has allowed for a more detailed classification of nevi. As such, dermoscopy identifies four main morphologic groups (i.e. globular, reticular, starburst and structureless blue nevi), one group of nevi located at special body sites (i.e. face, acral, nail) and one group of nevi with special features. This latter category consists of nevi of the former categories, which are typified by peculiar clinical-histopathological findings. They can be subdivided into 'melanoma simulators' including combined nevi, recurrent nevi and sclerosing nevus with pseudomelanomatous features, 'targetoid' nevi (i.e. halo, cockade, irritated targetoid haemosiderotic and eczematous nevus) and uncommon histopathological variants such as desmoplastic, white dysplastic or ballon cell nevus. While the dermoscopic and RCM patterns of the former categories have been studied in detail, little is currently known about the clinical morphology of the heterogeneous group of 'special' nevi. In this article, we describe the clinical, dermoscopic and RCM features of 'special' nevi and review the current literature on this group of melanocytic proliferations.

“…One of the most common dermoscopic aspects of combined nevi is the “target” appearance, with the blue pigmentation being present centrally within a larger lesion demonstrating browner or dark epithelial pigmentation. 14 Nevertheless, a combined nevus can also have a variety of clinical and dermoscopic presentations because of the combination of different histologic patterns and cannot be diagnosed with only a clinical examination and not always by means of dermoscopy. 15,16…”

“…Within the realm of melanocytic skin lesions the term targetoid haemosiderotic naevus is applied to a variant of traumatized, acquired melanocytic naevus, and some combined blue naevi may also assume a targetoid appearance 1,2 . This term, however, is not at all fitting for the naevus in question here.…”

“…The naevus differs from targetoid haemosiderotic naevus both clinically (long evolution, cockade‐like appearance) and histopathologically (absence of haemorrhage and haemosiderin deposition) 1 . The targetoid combined blue naevus has only two discrete areas representing dermal and epidermal melanocytic proliferations 2 . Because of this distinctive morphology of an otherwise usual, compound melanocytic naevus, we coined the term naevus en cocarde or hoop‐loop naevus .…”
