Résumé
INTRODUCTION: White lentiginosis is characterized by white guttate macules with a typical histological structure: lentiginosis hyperplasia with hypopigmentation. OBSERVATION: A 23-year-old woman, from Algeria, presented with white macules from 5 years ago. Few women in her family had the same trouble. Cutaneous examination revealed diffused white little macules. Histological examination showed a lentiginous hyperplasia of the epidermis, with elongated club-shaped rete ridges and an unusual loss of pigmentation. DISCUSSION: Different diagnosis should be discussed with disseminated leucoderma macules. Nevertheless, the only one which corresponds with our case is the white lentiginosis. To our knowledge, it is the first case described since Grosshans et al. in 1994. Our patient is a descendant of the original case's family. This new case appears to confirm the genetic origin of the disorder and suggests autosomal dominant or X-linked inheritance.
