Systemic lupus erythematosus (lupus) is a disease that causes your body’s immune system to attack its own cells and tissues. It causes periods of inflammation to various parts of the body. It can affect your joints, tendons, and skin. It can affect blood vessels. And it can affect organs such as the kidneys, heart, lungs, and brain.
Osteoarthritis is the most common form of arthritis. It is a chronic degenerative joint disease that affects mostly middle-aged and older adults. Osteoarthritis causes the breakdown of joint cartilage. It can occur in any joint, but it most often affects the hands, knees, hips, or spine.
Psoriatic arthritis is a form of arthritis associated with psoriasis. Psoriasis is a chronic skin and nail disease. It causes red, scaly rashes and thick, pitted fingernails. Psoriatic arthritis is similar to rheumatoid arthritis (RA) in symptoms and joint inflammation.
Raynaud's phenomenon is a disorder that causes decreased blood flow to the fingers. In some cases, it also causes less blood flow to the ears, toes, nipples, knees, or nose. This happens due to spasms of blood vessels in those areas. The spasms happen in response to cold, stress, or emotional upset.
Reactive arthritis is a type of arthritis that occurs due to an infection. Arthritis is when joints become inflamed and painful. Reactive arthritis is not contagious. It's also known as Reiter's Syndrome. It mostly affects men ages 20 to 40.
Scleroderma is an ongoing (chronic) disease that causes abnormal growth of connective tissue. It can affect the joints, skin, and internal organs. It is degenerative and gets worse over time.
Tendonitis is when a tendon is inflamed. When a tendon is inflamed, it can cause swelling, pain, and discomfort. Another problem called tenosynovitis is linked to tendonitis. This is the inflammation of the lining of the tendon sheath around a tendon.

Thalassemia is an inherited blood disorder. It is passed down from one or both parents through their genes. There are two main types of thalassemia: alpha and beta. Different genes are affected for each type. Thalassemia can cause mild or severe anemia.
Aplastic anemia occurs when your bone marrow doesn’t make enough red and white blood cells, and platelets.
Hemolytic anemia is a disorder in which red blood cells are destroyed faster than they are made.
The most common cause of anemia is a lack of iron. This is called iron deficiency.
Anemia is a common blood disorder. It occurs when you have fewer red blood cells than normal, or not enough hemoglobin in your blood. When you have anemia, your blood can’t carry enough oxygen to your body. Without enough oxygen, your body can’t work as well as it should.
Vitamin B12 deficiency anemia is a condition in which your body does not have enough healthy red blood cells, due to a lack (deficiency) of vitamin B12. This vitamin is needed to make red blood cells, which carry oxygen to all parts of your body.
Thalassemia is an inherited blood disorder that is passed down through the parent’s genes. It affects how hemoglobin is made. Hemoglobin is an iron-rich protein in red blood cells. It carries oxygen to all the parts of the body. There are two main types of thalassemia: alpha and beta. Thalassemia can cause mild or severe anemia.

Folate deficiency is the lack of folic acid in the blood. Folic acid is a B vitamin needed to make normal red blood cells. Low levels can cause megaloblastic anemia.
G6PD deficiency is an inherited condition. It is when the body doesn’t have enough of an enzyme called G6PD (glucose-6-phosphate dehydrogenase). This enzyme helps red blood cells work properly. A lack of this enzyme can cause hemolytic anemia. This is when the red blood cells break down faster than they are made.
Hereditary hemochromatosis is one of the most common genetic disorders in the U.S. Itcauses your body to absorb too much iron from the food you eat.
Immune thrombocytopenic purpura (ITP) is a blood disorder. With this disease, you have a lower amount of platelets than normal in your blood. Platelets are blood cell fragments that help with blood clotting. Having fewer platelets can cause easy bruising, bleeding gums, and internal bleeding.
Sickle cell disease (SCD) is an inherited blood disorder that causes the body to make abnormal hemoglobin. This is the protein in red blood cells that carries oxygen to all parts of your body. The damaged red blood cells block blood flow in small blood vessels. This causes pain and can damage major organs.
Thrombocythemia is a disease in which your bone marrow makes too many platelets. Platelets are blood cell fragments that help with blood clotting. Having too many platelets makes it hard for your blood to clot normally. This can cause too much clotting, or not enough clotting.
Thrombosis occurs when blood clots block your blood vessels. It may be caused by injury, immobility and other factors.
Polycythemia vera is a rare blood disorder in which there is an increase in all blood cells, particularly red blood cells. The increase in blood cells makes your blood thicker. This can lead to strokes or tissue and organ damage.
A chondroblastoma is a rare type of noncancerous bone tumor that begins in cartilage. This is the specialized, gristly connective tissue from which most bones develop. It plays an important role in the growth process. There are many different types of cartilage in the body. Chondroblastoma most often affects the ends of the long bones, near the growth plate, in the arms at the shoulder, and in the legs at the hip and knee. It is also called Codman’s tumor.
