livedoid vasculopathy

livedoid vasculopathy

A thrombogenic vasculopathy caused by fibrin thrombi in the small dermal vessels of the lower legs, especially in older women, which are attributed to decreased fibrinolytic activity in the blood coupled with defective release of intrinsic tissue plasminogen activator from vessel walls. The typical lesions are telangiectatic purpuric papules and plaques which evolve into crusted ulcers that heal into atrophic stellate scars.

Associations
Patients may also have livedo reticularis, scleroderma, systemic lupus erythematosus and cryoglobulinaemia.

We report the use of dermoscopy to further characterize such lesions in patients with early, non-ulcerated livedoid vasculopathy without clotting disorders.
Five consecutive patients (four females and one male between 43 and 50 years old) with painful livedoid vasculopathy of the ankles without ulcerations and without venous insufficiency were evaluated.
Glomerular vessels are not specific to livedoid vasculopathy. They have been described in chronic sun-damaged skin with precancerous lesions (5-7), in the periphery of hyperkeratotic Bowen's disease (8) and basal cell carcinoma (9), in poromas (10), in psoriasis (11), and in cutaneous leishmaniasis (12, 13).

Livedoid vasculopathy, also known as atrophie blanche and PURPLE (painful purpuric ulcers with reticular pattern of the lower extremities) is a rare, chronic vascular condition.
Livedoid vasculopathy may have periods of activity and remission.
We observed markedly enhanced functional stability of PAI-1 in patients with a rare thrombotic skin condition: livedoid vasculopathy [41].
observed that the functional stability of PAI-1 was markedly increased (nearly 43-fold) in plasma from the patients with thrombotic skin disorder such as livedoid vasculopathy. The mechanism of enhancing functional stability of PAI-1 activity is unknown.

In all of the cases analyzed, a differential diagnosis was performed between EG and Warfarin-induced skin necrosis, cocaine-induced skin necrosis, calciphylaxis, septic emboli, loxoscelism, diabetic microangiopathy, disseminated intravascular coagulation, necrotizing vasculitis, paraneoplastic extensive necrotizing vasculitis, pyoderma gangrenosum, livedoid vasculopathy, necrotizing fasciitis, and necrosis secondary to the use of vasoactive drugs.
