Description:

A screening of patient histories at the clinics of Dermatology of the universities of Zurich, Basel and Bern is performed in order to identify patients with a history of Livedoid vasculopathy. Patients with a history of livedoid vasculopathy are asked to participate in the study. The presence of Livedoid vasculopathy must be confirmed by a histologic specimen. After reading the patient information and if the informed consent is signed patients are included in the study. Patients are questioned about their smoking history and blood is drawn in order to perform a screening for thrombophilia. The presence of a history of smoking and thrombophilia is compared to the general Swiss population.
