[Focal acantholytic dyskeratosis in an intradermal pigmented nevus].

Dyskeratosis follicularis like changes are reported on a pigmented intradermal naevus (follicular infundibulum) from the nose of a 23 years old woman with no other stigmata of Darier's disease. These findings are discussed at the light of Ackerman's concept of focal acantholytic dyskeratosis and the relevant literature is reviewed.
