Halo Nevi Without Dermal Infiltrate

To the Editor.— In the November 1977 issue of theArchives(113:1572-1575), Brownstein et al presented a case of uninflamed halo congenital nevus without epidermal infiltrate. We already described a similar case in 1975, 1 and since then two new cases were observed during our histologic examination of 51 halo nevi. 2 We do not think that the lack of infiltrate is a characteristic of the congenital halo nevus but marks an evolutive stage. Like Roenigk et al, 3 we distinguish the halo nevi that persist over several years without involution of the tumor from the halo nevi accompanied by a rapid involution of the tumor. We think it is possible to distinguish the following pattern: Stage of perinevic vitiligo. This occurs generally on a single nevus. The clinical examination shows no inflammatory signs at the periphery. In immunofluorescence, no B lymphocytes are observed. This stage can last several
