Autoimmune and Inflammatory Diseases

41 conditions
Retroperitoneal Fibrosis
Deep within your abdomen, behind your intestines and stomach, lies a space called the retroperitoneum. This area houses vital structures including your kidneys, major blood vessels, and the tubes that carry urine from your kidneys to your bladder. Sometimes, for reasons doctors don't always understand, thick scar tissue begins forming in this hidden space, gradually wrapping around and squeezing these crucial organs.
Cutaneous Polyarteritis Nodosa
Cutaneous polyarteritis nodosa represents one of medicine's more puzzling conditions - a disease that attacks small and medium-sized blood vessels in the skin without involving internal organs. Unlike its more serious cousin, systemic polyarteritis nodosa, this skin-only version rarely threatens life but can cause significant discomfort and concern for those who develop it.
Linear IgA Disease
Linear IgA disease represents one of the rarer autoimmune blistering skin conditions that doctors encounter. This condition occurs when the body's immune system mistakenly attacks healthy skin tissue, creating painful blisters and sores that can appear anywhere on the body. The name comes from a specific antibody pattern doctors see under special microscopic testing.
Pemphigus Foliaceus
Pemphigus foliaceus represents one of the most challenging autoimmune skin diseases doctors encounter, affecting fewer than 1 in 100,000 people worldwide. This rare condition occurs when the body's immune system mistakenly attacks healthy proteins that hold skin cells together, causing painful blisters and erosions primarily on the face, scalp, chest, and back.
Goodpasture Syndrome
Goodpasture syndrome stands as one of medicine's most challenging autoimmune conditions, where the body's defense system turns against two vital organs: the lungs and kidneys. This rare but serious disorder occurs when antibodies mistakenly attack the basement membranes in these organs, causing potentially life-threatening inflammation and bleeding.
Vogt-Koyanagi-Harada Disease
Vogt-Koyanagi-Harada disease represents one of medicine's most puzzling autoimmune conditions, attacking multiple systems throughout the body with a precision that still baffles researchers. This rare inflammatory disease primarily targets melanin-containing tissues, creating a cascade of symptoms that can affect the eyes, ears, skin, and nervous system simultaneously.
Pemphigus Erythematosus
Pemphigus erythematosus represents one of the rarest forms of autoimmune blistering diseases, affecting fewer than 1 in 1 million people worldwide. This condition combines features of two different autoimmune disorders - pemphigus foliaceus and lupus erythematosus - creating a unique clinical picture that can puzzle even experienced dermatologists. Also known as Senear-Usher syndrome, it primarily targets the skin on sun-exposed areas, particularly the face and upper chest.
Cicatricial Pemphigoid
Cicatricial pemphigoid is a rare autoimmune blistering disease that primarily attacks the mucous membranes lining the mouth, eyes, nose, throat, and genital areas. Unlike other blistering conditions that heal without lasting damage, this disease has a particularly troubling characteristic: it leaves behind scars as it progresses.
Morphea (Localized Scleroderma)
Morphea represents a fascinating puzzle in autoimmune medicine - a condition where the body's immune system mistakenly attacks healthy skin tissue, causing patches of thick, hardened skin to develop. Unlike its more serious cousin, systemic scleroderma, morphea stays confined to the skin and underlying tissues, sparing internal organs from damage.
Autoimmune Hepatitis
When your body's immune system mistakenly attacks your liver, the result is autoimmune hepatitis - a chronic inflammatory condition that affects roughly 200,000 Americans. Unlike hepatitis caused by viruses or toxins, this form develops when the immune system becomes confused and treats healthy liver cells as foreign invaders.
Primary Biliary Cholangitis
Primary biliary cholangitis ranks among the most misunderstood autoimmune diseases affecting the liver. Despite its name, this condition has nothing to do with gallstones or blocked bile ducts from external causes. Instead, the body's own immune system mistakenly attacks the tiny bile ducts inside the liver, causing inflammation and scarring that can progress over many years.
Takayasu Arteritis
Takayasu arteritis is a rare inflammatory disease that attacks the body's largest blood vessels, particularly the aorta and its main branches. Named after the Japanese doctor who first described it in 1908, this condition causes the walls of these vital arteries to become inflamed, thickened, and sometimes blocked. The disease primarily strikes young women, typically between ages 15 and 40, earning it the nickname "pulseless disease" because weakened pulses are often an early sign.
Polyarteritis Nodosa
Polyarteritis nodosa represents one of medicine's more puzzling conditions - a rare disease where the body's immune system mistakenly attacks its own blood vessels. This systemic vasculitis primarily targets medium-sized arteries throughout the body, causing inflammation that can disrupt blood flow to vital organs including the kidneys, heart, liver, and nervous system.
Chronic Inflammatory Myopathy
Chronic inflammatory myopathy represents a group of rare autoimmune diseases that cause muscle weakness and inflammation throughout the body. These conditions occur when the immune system mistakenly attacks healthy muscle tissue, leading to progressive weakness that can significantly impact daily activities. The four main types include dermatomyositis, polymyositis, necrotizing autoimmune myopathy, and inclusion body myositis, each with distinct characteristics and treatment approaches.
Cutaneous Lupus Erythematosus
Roughly 70% of people with lupus develop some form of skin involvement, making cutaneous lupus erythematosus one of the most visible manifestations of this autoimmune condition. Unlike systemic lupus that affects multiple organs, cutaneous lupus primarily targets the skin, creating distinctive rashes and lesions that can significantly impact a person's daily life and self-confidence.
Systemic Lupus Erythematosus Carditis
Systemic lupus erythematosus carditis represents one of the most serious complications of lupus, affecting between 30 and 60 percent of people living with this autoimmune condition. When lupus attacks the heart, it can inflame any of the three layers that make up this vital organ - the outer protective sac, the heart muscle itself, or the delicate inner lining and valves.
Antiphospholipid Syndrome
Antiphospholipid syndrome represents one of medicine's more puzzling autoimmune conditions, where the body's immune system mistakenly attacks its own blood-clotting mechanisms. This creates a dangerous paradox: the blood becomes more likely to form clots in places where clots shouldn't form, while simultaneously becoming less able to clot properly when healing is needed.
Vascular Inflammation
Your blood vessels form an intricate highway system that carries life-sustaining nutrients and oxygen throughout your body. When inflammation strikes these vital pathways, it creates a condition doctors call vasculitis or vascular inflammation. This umbrella term describes a group of diseases where your immune system mistakenly attacks your own blood vessels, causing them to become swollen, narrowed, or weakened.
Acute Arteritis
Acute arteritis represents a group of inflammatory conditions that cause blood vessel walls to become swollen and inflamed. When this inflammation strikes suddenly, it can disrupt normal blood flow to vital organs and tissues throughout the body. The condition affects arteries of various sizes, from large vessels near the heart to smaller ones that supply muscles and organs.
Rheumatic Fever
Rheumatic fever remains one of the most preventable causes of heart disease in children worldwide. This inflammatory condition develops when the body's immune system mistakenly attacks its own tissues after fighting off a strep throat infection that wasn't properly treated.
