Abstract
Unusual changes in the melanin pigmentary system were observed on a warty papule biopsy taken from a patient with xeroderma pigmentosum (XP). Degenerated melanocytes full of lipids were observed from the basal layer up to the middle of the epidermis. The melanosomes were polymorphous, variable in size and shape with very strange aspects, such as spider-like and whirling configurations. The structure of the macromelanosomes suggests that they are large autophagosomes. These findings are discussed and compared with previous studies. Bei einer Patientin mit einem Xeroderma pigmentosum, und zwar in einer Biopsie einer warzigen Papel wurden unübliche Veränderungen im Malninsystem beobachtet. Degenerierte Melanocyten, die einen Lipidreichtum aufwiesen, wurden von der Basalschicht bis zur Mitte der Epidermis beobachtet. Die Melanosomen waren polymorph, unterschiedlich in Form und Ausdehnung und zeigten zudem spinnenartige und wirbelförmige Konfiguration. Die Struktur der Makromelanosomen ließen den Verdacht aufkommen, daß es große Autophagosomen sind. Diese Befunde werden diskutiert und mit vorhergehenden Untersuchungen verglichen.Keywords
