Kutane Polypose bei einer Patientin mit APC -Variante ohne adenomatöse Polypose des Kolons

The occurrence of multiple benign skin tumors is suspicious for a hereditary tumor syndrome. Genetic investigations often clarify the molecular foundations and enable a nosological classification. In the case of a cutaneous polyposis described here, a variant in APC was detected; however, simultaneous symptoms of an adenomatous polyposis of the colon were lacking.
