Coincidence of multiple, disseminated, eruptive-tardive blue nevi with cutis marmorata teleangiectatica congenita

Giant congenital cellular blue naevus of the scalp with disseminated common blue naevi of the body

“…Ikeda et al . reported a case of congenital giant cellular blue naevus with discrete common blue naevi that is similar to our patient 2 …”

“…Blue naevi are often present since birth or early childhood and thought to arise from dermal melanocytes that fail to complete their migration from the neural crest to the epidermis and hair bulb 1 . Common locations of blue naevi are the extremities, particularly the dorsal aspects of hands and feet, the buttocks and the face 2 . Giant congenital blue naevus is extremely rare, and most of the lesions were on the scalp 3 .…”

“…Blue naevus generally present as solitary lesion, but multiple blue naevi over the whole body are extremely rare 1,2 . Iglesias et al .…”

“…Krause et al . reported multiple disseminated blue naevi localized on the lower extremities 2 . Kasahara et al .…”

Eruptive blue nevi

“…Hundreds of blue papules [6] 31/female Left forearm 5×4 mm blue-black papule with fi ve surrounding 1-2 mm blue-black macules [7] 35/male Glans penis Four blackish-blue blue nevi 2-4 mm in diameter [8] 56/male Epigastric region Approximately 50 blue to black papules 2-5 mm in diameter [9] 63/female Dorsal right forearm and right hand Multiple blue-black papules 0.5-1 cm in diameter [10] 71/female Tibial area of both lower legs Approximately 40 gray to bluish papules 1-10 mm in diameter [11] 71/female Scalp 6 mm blue papule and 16 2-3 mm macules [12] 71/female Conjunctiva, upper and lower eyelids Multiple darkly pigmented raised lesions [13] 74/male Scalp Multiple blue-black nodules 4-6 mm in diameter [14] 76/male Left chest Three dark blue papules [15] as melanin-containing fibroblast-like cells grouped in irregular bundles admixed with melanin-containing macrophages; groups of melanocytes with excess fibrous tissue in middle or upper reticular dermis, occasionally extending down to subcutaneous fat and up to papillary dermis; elongated melanin-producing dermal melanocytes lying with their long axis parallel to the epidermis; and normal appearing epidermis. [1] We present this case of eruptive blue nevi on the scalp to highlight the rare location and the uncommonly high number of eruptive blue nevi in our patient.…”
