Abstract
Ultrastructural changes of Langerhans cells during spontaneous involution of plane warts were examined. In areas with activated macrophages and epidermal cell interaction, Langerhans cells showed signs of enhanced cellular activity with an increased number of Langerhans cell granules, as in contact dermatitis. The fine structure of Langerhans cell granules, however, was unusual in that the vesicular portion was surrounded internally by a membrane, and this portion frequently occurred independently taking the shape of a loop. Es wurden die ultrastrukturellen Veränderungen der Langerhansschen Zellen während der spontanen Involution der Plattenwarze untersucht. In den Gebieten mit aktivierten Makrophagen und epidermischen Zellen zeigten die Langerhansschen Zellen, wie in der Kontaktdermatitis, ein Zeichen erhöhter cellulärer Aktivität mit Vermehrung der cellulären Körner. Ungewöhnlich an der feinen Struktur der Körner der Langerhansschen Zellen war, daß der vesiculäre Teil innen mit einer Membrane umgeben wurde und daß dieser Teil häufig in Gestalt einer Schlinge vorkam.This publication has 15 references indexed in Scilit:
