A Girl with Hypopigmented Patch on Cheek
Nevus depigmentosus (nevus achromicus) is a rare congenital non-progressive hypopigmented nevus related to morphological abnormalities of melanosomes. A 6-year-old girl was brought with solitary hypopigmented patch with irregular, but well-defined, border on cheek of the left cheek since birth. On diascopy, the margin of the lesion did not fade. Diascopy showed off white lesion with faint pigment network over the lesion, and serrated borders extending onto the normal skin as “pseudopods.” Nevus depigmentosus usually doesn’t require any active treatment, but various treatment modalities include Camouflage, surgical grafting and excimer laser may be tried for cosmetic reasons.
