THE HISTOLOGY OF SUTTON'S NAEVUS

ANY process wliich makes a cellular naevus disappear is of theoretical interest, and in Sutton's naevais this sometimes happens. Here, a \itiliginou8 condition not only depigm.ent8 the centrally placed naevus at times, but may bring about its destruction. This morphological change conflicts with the prevailing view of vitiligo as a purely biochemical lesion. The literature, well reviewed by Fisher and Leider (1949), is uuhelpful on these topics. Eight Suttou's uaevi were subjected to histological study, stained with haematoxyliii and eoain, and examined with these problems in mind.
