"Leukoderma" Natural Recordings by Native Speakers
Leukoderma is a medical term that refers to a group of skin disorders characterized by the loss of skin pigmentation, resulting in white patches or depigmented areas on the skin. These conditions can be caused by various factors, including genetic mutations, environmental factors, and autoimmune disorders. Common types of leukoderma include vitiligo, piebaldism, and leprosy.
Leukocytoclastic is an adjective. It refers to a histopathological pattern characterized by the presence of fragmented neutrophils, typically seen in conditions associated with vasculitis, such as Henoch-Schönlein purpura, Sweet's syndrome, and Behçet's disease. The term is derived from Greek words leukos (white), cyto (cell), and klastikos ( fragmentation).
Leukocytoid refers to a type of cell that resembles a white blood cell (leukocyte) in appearance, but is not actually a true white blood cell. These cells can be found in various conditions, including benign or malignant neoplasms, and their resemblance to leukocytes can sometimes lead to misdiagnosis.
Leukocytolysis is a medical term that refers to the destruction or fragmentation of white blood cells (leukocytes) within tissues or organs, especially in response to inflammation or infection. It is often accompanied by the release of cellular contents, such as enzymes and proteins, into the surrounding tissues, which can cause damage and tissue necrosis.
Leukocytopenia is a medical term that refers to a condition characterized by a decreased count of white blood cells (leukocytes) in the blood. White blood cells are an essential part of the immune system, and a low count can leave a person susceptible to infections. Leukocytopenia can be caused by various factors, including infections, medication side effects, bone marrow disorders, and autoimmune diseases. Treatment for leukocytopenia typically involves addressing the underlying causes and may involve medication, blood transfusions, and other therapies to help restore a normal white blood cell count.
Leukocytosis is a medical term that refers to an increase in the number of white blood cells in the blood.
Leukocytozoon is a noun that refers to a type of parasitic infection caused by a protozoan parasite called Leukocytozoon. The infection typically affects birds, but can also be found in other animals, including cats and dogs. In birds, Leukocytozoon can cause a range of symptoms, including anemia, pale comb and wattles, and respiratory distress. The parasite is typically transmitted through the bite of an infected mosquito.
Leukoedema is a type of white patch or discoloration that appears on the lining of the mouth. It is a benign and harmless condition that is caused by the appearance of white cells on the mucous membranes. Leukoedema is more common in older adults and may be triggered by smoking, poor oral hygiene, or certain medications. The patches are usually white or grayish-white and can appear anywhere inside the mouth, including the tongue, cheeks, and lips. They do not cause harm and can be easily treated with improved oral hygiene and medical treatment if necessary.
Leukoencephalopathy is a medical term that refers to a group of neurological disorders that affect the white matter of the brain. It is characterized by degeneration or damage to the fatty insulation (myelin) that surrounds the nerve fibers in the brain, leading to symptoms such as cognitive impairment, mood changes, and difficulty with balance and coordination. Leukoencephalopathy can be caused by various factors, including infection, inflammation, autoimmune disorders, and exposure to toxins or medications.
Leukonychia is a medical term that refers to the small white spots or rings on the surface of the nails, often caused by minor trauma or damage to the nail bed. It is a common condition and can occur in anyone, although it is more noticeable in people with lighter-colored nails.
Leukopenia is a condition in which the number of white blood cells in the bloodstream is reduced below normal levels.
Leukopheresis is a medical procedure that involves the removal of white blood cells (leukocytes) from a patient's blood. This is typically done to help regulate the body's immune response in conditions such as immune disorders, autoimmune diseases, or cancer. The removed white blood cells can then be used for transfusions or further treatment. Leukopheresis is also known as leukapheresis.
Leukophoresis is a medical procedure where a patient's white blood cells are removed from their blood and filtered to remove abnormal or diseased cells, typically in cases of leukemia or myeloma.
Leukoplakia is a medical term that refers to patches of white membrane or mucous that form on the mucous membranes of the body, usually on the tongue, mouth, throat, or genitals. It is often a benign condition, but in some cases, it can be a sign of a more serious underlying health issue, such as oral cancer.
