Klippel-Trenaunay-Weber Syndrome
Klippel-Trènaunay-Weber (KTW) syndrome is a condition characterized by: port-wine stains or birthmark malformations in the skin, soft tissue and bony growths (generally involving a limb), and vascular anomalies (varicose veins). Although these three symptoms are consistently found in patients with Klippel-Trènaunay-Weber syndrome, there are other symptoms, which include atrophy (a limb that is underdeveloped), fingers and toes that are disproportionately large or small, digits that are webbed (syndactyly), too many digits (polydactyly), or too few digits (oligodactyly). The cause of Klippel-Trènaunay-Weber syndrome is not known. However, recently there have been some cases that run in families. There is no significant treatment for Klippel-Trènaunay-Weber syndrome.
Lupus (Systemic Lupus Erythematosus or SLE)
Systemic lupus erythematosus is a condition characterized by chronic inflammation of body tissues caused by autoimmune disease. Lupus can cause disease of the skin, heart, lungs, kidneys, joints, and nervous system. When only the skin is involved, the condition is called discoid lupus. When internal organs are involved, the condition is called systemic lupus erythematosus (SLE).
Rosacea
Rosacea is a skin disease that causes redness of the forehead, chin, and lower half of the nose. In addition to inflammation of the facial skin, symptoms include dilation of the blood vessels and pimples (acne rosacea) in the middle third of the face. Oral and topical antibiotics are treatments for rosacea. If left untreated, rhinophyma (a disfiguring nose condition) may result.
Scleroderma
Scleroderma is an autoimmune disease of the connective tissue. It is characterized by the formation of scar tissue (fibrosis) in the skin and organs of the body, leading to thickness and firmness of involved areas. Scleroderma is also referred to as systemic sclerosis, and the cause is unknown. Treatment of scleroderma is directed toward the individual features that are most troubling to the patient.
