Abstract

Lichenoid reactions have been described as a side effect of several drugs. Here we describe the development of lichen planus (LP) of the mammilla following off-label use of denosumab in an adolescent patient with mono-ostotic fibrous dysplasia. Lichen planus is considered an autoimmune disorder. Since receptor activator of nuclear factor κΒ ligand (RANKL), the target of denosumab action, has regulatory function in the immune system, it is feasible, that LP may be caused as part of an immunological dysregulation.

Zusammenfassung

Lichenoide Reaktionen sind als Nebenwirkung unterschiedlicher Medikamente beschrieben. Wir berichten die Entwicklung von Lichen planus (LP) der Brustwarze bei einem jugendlichen Patienten mit mono-ostotischer Fibröser Dysplasie der off-label mit Denosumab behandelt wurde. Für den Lichen planus wird eine auto-immunologische Genese angenommen. Da receptor activator of nuclear factor κΒ ligand (RANKL), als Zielstruktur von Denosumab, regulatorische Funktionen im Immunsystem hat, ist die Induktion einer autoimmunologischen Genese denkbar.
