Leukocytoclastic angiitis is a rare autoimmune condition characterized by inflammation of small blood vessels.​ Symptoms include skin rash, fever, joint pain, and bleeding.​ Diagnosis is confirmed through biopsy. Treatment involves corticosteroids and immunosuppressants.​ Prognosis varies based on severity and response to treatment.​

Introduction

Leukocytoclastic angiitis, also known as cutaneous small-vessel vasculitis, is a rare autoimmune disorder characterized by the inflammation of small blood vessels.​ It primarily affects the skin, causing skin rash, but it can also involve other organs.​ The exact cause of this condition is unknown, but it is thought to arise from the immune system mistakenly attacking the body’s own blood vessels.​

Leukocytoclastic angiitis typically presents with palpable purpura, a skin rash comprised of small, raised hemorrhages.​ Patients may also experience systemic symptoms such as fever, joint pain, and gastrointestinal issues.​ In severe cases, the inflammation can lead to bleeding in various organs.​ Prompt diagnosis and treatment are crucial to prevent complications and long-term damage.

Due to its rarity and varied presentation, leukocytoclastic angiitis can be challenging to diagnose.​ It requires a comprehensive evaluation that often involves a skin biopsy to confirm the presence of leukocytoclastic vasculitis. Additionally, other tests may be conducted to assess organ involvement and rule out other conditions with similar symptoms.​

Managing leukocytoclastic angiitis revolves around suppressing the immune response causing the inflammation.​ The mainstay of treatment includes corticosteroids to reduce inflammation and immunosuppressants to modulate the immune system.​ The prognosis of leukocytoclastic angiitis varies depending on the extent of organ involvement and the individual’s response to treatment.

Symptoms

Leukocytoclastic angiitis presents with a range of symptoms, primarily affecting the skin and occasionally involving other organs.​ The hallmark symptom is a skin rash called palpable purpura, characterized by small, raised areas of bleeding under the skin.​ These purpuric lesions typically appear on the lower extremities but can occur on any part of the body.

Patients with leukocytoclastic angiitis may experience systemic symptoms such as fever, joint pain, and malaise.​ The skin rash may be accompanied by itching or burning sensations. In severe cases, individuals may develop ulcers or large hemorrhagic lesions on the skin due to the inflammation of blood vessels.​

Aside from the skin manifestations, leukocytoclastic angiitis can involve other organs leading to a variety of symptoms.​ Gastrointestinal involvement may cause abdominal pain, nausea, vomiting, or bloody diarrhea.​ Joint pain, termed arthralgia, can affect multiple joints and may be debilitating. Inflammation of blood vessels in the kidneys can result in kidney damage, leading to symptoms such as blood in the urine, swelling, or changes in urination patterns.​

In rare instances, leukocytoclastic angiitis can affect the nervous system, leading to symptoms like numbness, tingling, weakness, or even stroke-like symptoms.​ This highlights the systemic nature of the condition, emphasizing the importance of a comprehensive evaluation to assess the extent of organ involvement and tailor treatment accordingly.​

Diagnosis

Diagnosing leukocytoclastic angiitis entails a comprehensive approach involving clinical evaluation, laboratory tests, imaging studies, and in some cases, a biopsy of the affected tissue.​ The initial step in diagnosing this condition is a thorough medical history and physical examination to assess the presenting symptoms and their progression.
