“…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 …”

“…In our case, the histology was similar to that of Mongolian spots and nevi of Ota, two entities in which malignant transformation has previously been described. Several cases have described ABN coexisting with nevus spilus or have had nevus spilus developing within them . It is important to be aware of the overlap between nevus spilus and ABN, because superficial spreading melanoma has been reported to develop within nevus spilus …”

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.

Several types of maculopapular melanocytic naevi can occur in a multiple form, and be arranged in a nonrandom fashion on the skin. The most frequently reported segmentally grouped naevi are lentigines. Two types of segmentally arranged lentigines probably exist. The first is associated with neurofibromatosis (NF)1 or NF1 signs, features scattered light-brown lesions and can be considered a type of mosaic NF1. By contrast, non-NF1 associated lesions are characterized by densely packed, dark lesions, and can be defined as 'non-NF1 checkerboard-arranged lentigines'. Blue naevi, Spitz naevi and common acquired melanocytic naevi can occur, clustered in an agminated (or cannonball) shape. However, if large enough, they always follow a checkerboard pattern. Hence, such mosaic conditions should be termed 'checkerboard-arranged blue naevi', 'checkerboard-arranged Spitz naevi' and 'checkerboard-arranged common acquired melanocytic naevi'. Segmentally arranged dysplastic melanocytic naevi probably represent a mosaic form of dysplastic naevus syndrome. Dysplastic melanocytic naevi confined to a cutaneous segment could be defined as 'isolated segmental dysplastic naevus syndrome', while segmentally arranged dysplastic melanocytic naevi co-occurring with widespread, nonsegmental dysplastic melanocytic naevi might configure a 'superimposed segmental dysplastic naevus syndrome'. Small congenital melanocytic naevi are always grouped along Blaschko lines. The only other instances following Blaschko lines are the so-called 'linear lentiginous naevus' and a unique case of multiple deep penetrating naevi.
