Informations about the disease
Das Spektrum der Hauttumoren ist vielfältig; sie können aus verschiedensten normalen Gewebestrukturen hervorgehen. Tumoren der Hautanhangsgebilde (Adnexen) entstehen aus Strukturen wie Haarfollikeln sowie Schweiß- und Talgdrüsen. Da diese Tumoren oft keine klinischen Merkmale aufweisen, die eine eindeutige Diagnose ermöglichen, erfolgt die Bestimmung des Tumortyps typischerweise erst nach einer Biopsie und der dermatopathologischen Untersuchung. Das Auftreten multipler Tumoren kann auf eine seltene genetische Ursache hinweisen und mit einer Krebsprädisposition in anderen Organen einhergehen. Inzwischen sind zahlreiche krankheitsverursachende Gene identifiziert, was bei Verdacht auf ein solches Syndrom eine genetische Beratung ermöglicht.
