Alles wat je moet weten over cutane vasculitis bij huidziekten

How to Confirm If You Have Vasculitis Rash

If you think you have a vasculitis rash, it's important to see a healthcare provider and, if possible, a dermatologist (a physician specializing in skin diseases).

During the diagnostic process, a dermatologist will:

• Analyze your symptoms
• Look for abnormalities in a physical examination
• Evaluate the results of various tests, including blood work and a skin biopsy

Medical History and Physical Exam

When evaluating for possible cutaneous vasculitis, a dermatologist will ask about skin symptoms, drug exposures, family medical histories, and past or present health conditions, such as a recent viral infection.

They will also inquire about other non-skin symptoms, which, if present, can suggest systemic vasculitis (affecting other areas of the body) or an underlying disease.

Systemic vasculitis indicates that blood vessels in organs other than the skin—for example, the liver, kidney, joints, or nerves—are inflamed.

Symptoms of Systemic Vasculitis

Systemic vasculitis is a more serious, potentially dangerous condition than vasculitis limited to the skin. Symptoms of systemic vasculitis can include:

• Fever, chills, and night sweats
• Unintended weight loss
• Fatigue and malaise (generalized feeling of being unwell)
• Joint and muscle aches
• Abdominal pain
• Blood in the urine or stool
• Numbness and weakness
• Cough or sinus inflammation
• Vision changes

Next, a dermatologist will carefully inspect the affected skin area and perform a complete body examination.

Skin Biopsy

A skin biopsy is necessary to confirm or exclude a diagnosis for any skin finding resembling a vasculitis rash.

Though there are different types of skin biopsy techniques, a punch biopsy is often used when a vasculitis rash is suspected because it can go deep into the skin's layers.

Cutaneous vasculitis, An algorithmic approach to diagnosis

Vasculitides, characterized by inflammation and damage of blood vessels, encompass a broad spectrum of diseases. They can occur with different pathophysiological mechanisms and have a rich clinical heterogeneity depending on the vessel diameters they affect. Vasculitides may also present with a broad spectrum of severity, ranging from a mild self-limiting to a potentially life-threatening disease. The high prevalence of skin involvement in vasculitis, visible character and, finally, the easy accessibility of the skin for both physical examination and biopsy offers important advantages for prompt disease recognition and diagnosis. Thus, dermatologists are privileged to diagnose the disease earlier and more effectively than any other discipline. As a consequence, a detailed clinical and histopathological evaluation of the skin is one of the most critical steps in diagnosing vasculitis. Besides obtaining a good medical history, laboratory and radiological evaluation methods are used in the diagnosis. In this review, a practical and algorithmic approach is aimed to assist in the diagnosis of vasculitis. However, this approach should not be seen as strict rules. This stepwise algorithmic diagnostic approach for vasculitis was developed by combining the current literature knowledge and the author's experience in this field to provide a rational framework for selecting the most appropriate among various diagnostic approaches.

Vasculitis refers to a broad and heterogeneous disease spectrum characterized by inflammation and damage of the blood vessel. It may occur in any organ of the body. When skin vessels are affected, the term cutaneous vasculitis is used. In systemic vasculitis, blood vessels of at least one organ are affected in addition to the skin. Of note, besides being a component of systemic vasculitis, including the skin, cutaneous vasculitis can be a skin-limited or skin-dominant expression or variant of systemic vasculitis. Finally, it may be a single-organ vasculitis of the skin (1). The skin is one of the most frequently affected organs in vasculitis, and small-vessel vasculitis of the skin is the most common vasculitis dermatologists encounter in their clinical practice (2). While the disease affects both genders equally, its frequency increases with age at diagnosis. Cutaneous vasculitis may present at any age, but it is more common in adults than children. The clinical course of the disease is usually self-limiting in children, and IgA vasculitis is the most common vasculitis in this age group. Idiopathic etiology is more prominent in adults and infectious etiology in children. Compared with children, underlying systemic vasculitis, connective tissue disease, or malignancy are more common in adult patients (3, 4).

Vasculitis Symptoms by Body Part

The symptoms of vasculitis may differ depending on the cause and type. Additionally, different types of vasculitis can affect other parts of the body. For example, Takayasu arteritis is a type of vasculitis that affects about one or two people per million and has symptoms of low blood pressure, low pulse, fever, and weight loss. Other types can lead to symptoms in different body parts.

Legs

Vasculitis can prevent blood flow to areas farther away from the core of the body. For example, blood flow to the legs may be reduced, causing tingling, pain, or swelling. The same symptoms can also affect the arms.

Some types of vasculitis that involve leg symptoms include:

• Anti-GBM disease or Goodasture's syndrome
• IgA vasculitis or Henoch-Schonlein Purpura (HSP)
• Polyarteritis nodosa (PAN)
• Takayasu's arteritis (TAK)

Hands

Types of vasculitis affecting the hands, such as Buerger's disease or thromboangiitis obliterans, cause tingling in the hands and fingers. In some cases, it can lead to gangrene, a condition that causes discoloration and tissue death. People with vasculitis symptoms in their hands may also experience swelling.

Internal Organs

Vasculitis can lead to symptoms that affect internal organs. This may include chest, abdomen, or lower back pain if the heart, lungs, digestive tract, or kidneys are affected. Lung and respiratory symptoms may also include shortness of breath, coughing up blood, nasal congestion, and nosebleeds. Additionally, blood in the urine can be a symptom of vasculitis that has affected the kidneys, and blood in the stool can be a symptom that it has affected the stomach or digestive tract.

Ears

Vasculitis can lead to symptoms related to the ears, including tinnitus (ringing in the ears) or hearing loss.

Dizziness is another symptom that can happen if vasculitis affects the ears. This is because parts of the inner ears send signals to the brain about balance based on the movements of the head. The swelling or inflammation of vasculitis in the ears can affect this balance system, leading to dizziness.

Introduction

Schamberg disease represents the most common type of pigmented purpuric dermatoses (PPDs), a chronic, benign, cutaneous eruptions characterized by petechiae, purpura, and increased skin pigmentation (brown, red, or yellow patchy). The PPDs are grouped into five clinical entities: Schamberg's purpura, Majocchi purpura, lichen aureus, Gougerot-Blum purpura and, eczematoid-like purpura of Doucas and Kapetanakis.[1]

The exact cause of Schamberg disease is not known. It is caused by extravasation of blood vessels particularly capillaries which allow red blood cells to get deposited into the skin which then releases their iron from hemoglobin. This iron causes a rust color accounting for the orange or brown tint of the rash.[4]

The exact cause of capillary inflammation is unknown and can be multifactorial. Potential contributors in the etiology can be:

Drugs such as acetaminophen, aspirin, adalin, amlodipine, carbromal, chlordiazepoxide, glipizide, glybuzole, hydralazine, meprobamate, nitroglycerin, persantin, reserpine, thiamine, interferon-alfa, injection medroxyprogesterone acetate, topical fluorouracil, and sildenafil[7][8][9][10][11]
