Livedoid vasculiltis associated with a double heterozygous Factor V Leiden and prothrombin G20210A gene mutations.
Livedoid vasculitis (LV) may be an isolated condition or associated with an underlying systemic disease, including coagulation disorders, periarteritis nodosa and systemic autoimmune diseases. The classic histological features of LV (fibrin deposition on dermal vessels and the absence of important perivascular infiltrate or leucocytoclasia) argue against a primary vasculitis and is more in keeping with a thrombotic process. Factor V Leiden mutations have rarely been reported in association with LV. We report a patient with LV, who had doubly inherited thrombophilia, with heterozygous mutations in the Factor V Leiden (G1691A) and prothrombin (G20210A) genes.
