About this study
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. 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.

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.

What is being measured
The primary outcome is the main question the study is designed to answer.
Smoking history: Patients will be asked if they currently smoke or if they are former smokers. If one of both items is yes, it means a positive answer.
The primary endpoint is the comparison of a positive smoking history and other cardiovascular risk factors of patients with livedoid vasculopathy with the Swiss general population.
Measured: 22 months
Secondary outcomes (1)
Thrombophilia screening: the following parameters will be determined in every participant: Factor V Leiden, Prothrombin 20210; Protein C, Protein S, Antithrombin III, Beta 2 Glykoprotein 1, Lupus Antikoagulans
The secondary endpoint is the search for thrombophilia in patients with livedoid vasculopathy.
Measured: 22 months
