Abstract:
The nevus spilus, also called speckled lentiginous nevus, presents itself as a patch of melanization dotted by smaller macules of darker color, frequently occuring on the trunk, and in some respect, resembeing the cafe au lait of von Recklinghausens disease and Albrights syndrome. We present clinical and histopathologic observation made on 14 patients, 13 male and 1 female, who agreed to go through a biopsy, during 5 years period from 1975 to 1980. The age at the visit ranged from 11 years to 61, with a mean of 22. 4. The location of lesions were shouIder (in 5 cases), neck (in 2), back (in 2), trunk (in 4),arm (in 1), and buttock (in 1). The epidermal changes consist of hypererkatosis (in 7), acanthosis (in 6), elongation of rete ridge and papillomatosis (in 9), basilar hypermelanosis (in 14), and nevus cell nests(in 3) The dermal changes consists of mild perivascular lymphoid and histiocytic cellular infiltrations (in 11), chromatophores (in 8) and dilated blood vessels (in 6). It is suggested that nevus spilus should be considered as a giant lentigo, a neoplasia of epictermal melanocytes, where junctional nevus is to develop.
