Giant zosteriform nevus spilus

Sir, speckled and lentiginous nevi may be viewed as a type of congenital melanocytic lesion which is lentiginous in early childhood and which might develop palpable components at puberty in a ‘speckled’ distribution. speckled and lentiginous nevus is a relatively uncommon entity. it is postulated that nevus spilus represents a localized defect in neural crest melanoblasts and occurs in fewer than 0.2% of all newborns and 1.2% of white school children. it is comprised of a flat, macular component, subtly darker shade than the surrounding skin, resembling a café-au-lait spot. within this pale background, there are lentigo-like lesions and also elevated darker-brown nevi. pathological examination shows, as the clinical appearance suggests, a background macular lesion with a very subtle increase in melanocytes, and lentigines with superimposed individual compound nevi. we are reporting a case of segmental lentiginous and speckled nevus.
