Livedoid Dermatitis is a rare skin condition characterized by painful, ulcerative lesions that predominantly affect the lower extremities. The condition is also known as Livedoid Vasculopathy and Atrophie Blanche.
Etiology
The exact cause of Livedoid Dermatitis is unknown. However, it is believed to be associated with certain conditions such as thrombophilia, hypercoagulable states, and autoimmune diseases.
Clinical Presentation
Patients with Livedoid Dermatitis typically present with painful, ulcerative lesions on the lower extremities. These lesions are often surrounded by a livedoid, or net-like, pattern of erythema. Over time, the lesions may heal with atrophic, porcelain-white scars known as Atrophie Blanche.
Diagnosis
Diagnosis of Livedoid Dermatitis is primarily based on clinical presentation and histopathological examination of skin biopsies. The histopathology typically shows fibrinoid necrosis of the dermal vessels and a perivascular lymphocytic infiltrate.
Treatment
Treatment of Livedoid Dermatitis is challenging and often requires a multidisciplinary approach. Options include anticoagulants, antiplatelet agents, immunosuppressants, and pain management strategies.
Prognosis
The prognosis of Livedoid Dermatitis is variable. While the condition is not life-threatening, it can significantly impact the quality of life due to chronic pain and recurrent ulcerations.
