Congenital Garment Nevus (Giant Nevus) | Biomedgrid llc

A 4() year old male from a suburban area of Spain, presented to our Clinic with respiratory symptoms. On examination we observed a dark hypermelanotic lesion on the dorsal and lumbar regions with areas of hypertrichosis on the lateral borders of this ovaloid shaped and dark skin patch. The affected area had a smooth and leathery appearance along with variegated lesions, light brown to black patches or plaques with smaller macules and papules (satellite nevi) in addition. (Figure 1) [1]. The patient admitted that he was born with this patch and had been diagnosed of dorsal Nevus, he also assured that the lesion had decreased in size over time [2]. This Clinical Image belongs to a Congenital Giant Nevus, (Figure 1) a type of hypermelanosis [3] _CongenitaI Nevi are often larger than Nevi that appear later in life. Garment Nevi also called Giant Nevi involve a very large body surface area-the entire back or a limband occur in 1/500,000 newborns. The frequency of Malignant transformation (Melanomas) in Congenital Nevi has been estimated to be between 2 and 20 per cent, although an incidence of 5 per cent was reported in a prospective series of 80 children. Rarely other neuroectodermal neoplasms develop in Congenital Nevi.
