title: The Nägeli-Franceschetti-Jadassohn syndrome: A hereditary ectodermal defect leading to colloid-amyloid formation in the dermis.
abstract: Light- and electron-microscopical examination of 4 skin biopsies from 2 members of the initially described family with Nägeli-Franceschetti-Jadassohn syndrome revealed that the already reported pigment incontinence is accompanied by varying amounts of colloid-amyloid bodies located in the superficial dermis. Occasionally, such bodies could also be seen around sweat glands in the reticular dermis. These findings indicate that cutaneous colloid-amyloid formation could be a pathogenic factor in the phenotypic expression of this autosomal dominant syndrome.
