AABSTRACT

A 52 years old female presented with asymptomatic hyperpigmented patches on the neck present since 10 years .on examination, Intermittent arborizing lines in various lengths and tiny stellate brownish macules over the both sides of the neck (Figure 1A,B).Other flexural areas were uninvolved. There were no systemic abnormalities or family histories of inherited disease There was no history of prolonged exposure to ultraviolet. There was no involvement of the hair, nail and mucous membranes. Dermatoscopy of the lesions showed pigmented dots and globules over the Langer's lines (Figure 1C). Histopathology of the lesions shows epidermal atrophy, flattening of rete ridges, and increased basal hyperpigmentation with melanophages in the dermis (Figure 1D]. The clinical and pathological features above were not consistent with any pigmentary skin disorders. So,The diagnosis of arborizing and stellate melanosis (ASM) was made. In our case, the lesions are exclusively distributed in the neck, unlike the only published case of ASM by Zhang Y, Tan C, which showed distribution in both the neck and upper chest.
