Label	Id	Description
Lupus Erythematosus, Discoid	D008179	[A chronic form of cutaneous lupus erythematosus (LUPUS ERYTHEMATOSUS, CUTANEOUS) in which the skin lesions mimic those of the systemic form but in which systemic signs are rare. It is characterized by the presence of discoid skin plaques showing varying degrees of edema, erythema, scaliness, follicular plugging, and skin atrophy. Lesions are surrounded by an elevated erythematous border. The condition typically involves the face and scalp, but widespread dissemination may occur.]
Lupus Erythematosus, Systemic	D008180	[A chronic, relapsing, inflammatory, and often febrile multisystemic disorder of connective tissue, characterized principally by involvement of the skin, joints, kidneys, and serosal membranes. It is of unknown etiology, but is thought to represent a failure of the regulatory mechanisms of the autoimmune system. The disease is marked by a wide range of system dysfunctions, an elevated erythrocyte sedimentation rate, and the formation of LE cells in the blood or bone marrow.]
Lupus Nephritis	D008181	[Glomerulonephritis associated with autoimmune disease SYSTEMIC LUPUS ERYTHEMATOSUS. Lupus nephritis is histologically classified into 6 classes: class I - normal glomeruli, class II - pure mesangial alterations, class III - focal segmental glomerulonephritis, class IV - diffuse glomerulonephritis, class V - diffuse membranous glomerulonephritis, and class VI - advanced sclerosing glomerulonephritis (The World Health Organization classification 1982).]
Lupus Vasculitis, Central Nervous System	D020945	[Central nervous system vasculitis that is associated with SYSTEMIC LUPUS ERYTHEMATOSUS. Clinical manifestations may include DEMENTIA; SEIZURES; CRANIAL NERVE DISEASES; HEMIPARESIS; BLINDNESS; DYSPHASIA; and other neurological disorders.]
Lupus Vulgaris	D008177	[A form of cutaneous tuberculosis. It is seen predominantly in women and typically involves the NASAL MUCOSA; BUCCAL MUCOSA; and conjunctival mucosa.]
Lutembacher Syndrome	D008185	[A condition characterized by a combination of OSTIUM SECUNDUM ATRIAL SEPTAL DEFECT and an acquired MITRAL VALVE STENOSIS.]
Luteoma	D018311	[An ovarian neoplasm composed of LUTEAL CELLS derived from luteinized GRANULOSA CELLS and THECA CELLS. Luteomas respond to GONADOTROPINS, and vary in their hormone production (PROGESTERONE; ESTROGENS; or ANDROGENS). During PREGNANCY, a transient type of luteoma may develop due to an exaggerated LUTEINIZATION of the OVARY.]
Lyme Disease	D008193	[An infectious disease caused by a spirochete, BORRELIA BURGDORFERI, which is transmitted chiefly by Ixodes dammini (see IXODES) and pacificus ticks in the United States and Ixodes ricinis (see IXODES) in Europe. It is a disease with early and late cutaneous manifestations plus involvement of the nervous system, heart, eye, and joints in variable combinations. The disease was formerly known as Lyme arthritis and first discovered at Old Lyme, Connecticut.]
Lyme Neuroborreliosis	D020852	[Nervous system infections caused by tick-borne spirochetes of the BORRELIA BURGDORFERI GROUP. The disease may affect elements of the central or peripheral nervous system in isolation or in combination. Common clinical manifestations include a lymphocytic meningitis, cranial neuropathy (most often a facial neuropathy), POLYRADICULOPATHY, and a mild loss of memory and other cognitive functions. Less often more extensive inflammation involving the central nervous system (encephalomyelitis) may occur. In the peripheral nervous system, B. burgdorferi infection is associated with mononeuritis multiplex and polyradiculoneuritis. (From J Neurol Sci 1998 Jan 8;153(2):182-91)]
Lymphadenitis	D008199	[Inflammation of the lymph nodes.]
Lymphadenopathy	D000072281	[Disease of LYMPH NODES which are abnormal in size, number or consistency.]
Lymphangiectasis	D008200	[A transient dilatation of the lymphatic vessels.]
Lymphangiectasis, Intestinal	D008201	[Dilatation of the intestinal lymphatic system usually caused by an obstruction in the intestinal wall. It may be congenital or acquired and is characterized by DIARRHEA; HYPOPROTEINEMIA; peripheral and/or abdominal EDEMA; and PROTEIN-LOSING ENTEROPATHIES.]
Lymphangioleiomyomatosis	D018192	[A disease characterized by the progressive invasion of SMOOTH MUSCLE CELLS into the LYMPHATIC VESSELS, and the BLOOD VESSELS. The majority of the cases occur in the LUNGS of women of child-bearing age, eventually blocking the flow of air, blood, and lymph. The common symptom is shortness of breath (DYSPNEA).]
Lymphangioma	D008202	[A benign tumor resulting from a congenital malformation of the lymphatic system. Lymphangioendothelioma is a type of lymphangioma in which endothelial cells are the dominant component.]
Lymphangioma, Cystic	D018191	[A cystic growth originating from lymphatic tissue. It is usually found in the neck, axilla, or groin.]
Lymphangiomyoma	D008203	[A tumorlike condition characterized by SMOOTH MUSCLE and ENDOTHELIUM proliferation of LYMPHATIC VESSELS and LYMPH NODES in the MEDIASTINUM and retroperitoneum, also in the lung. It may be manifested by chylous PLEURAL EFFUSION and ASCITES.]
Lymphangiosarcoma	D008204	[A malignant tumor originating from the endothelial cells of lymphatic vessels. Most lymphangiosarcomas arise in an arm secondary to radical mastectomy but they sometimes complicate idiopathic lymphedema. The lymphedema has usually been present for 6 to 10 years before malignant changes develop. (From Dorland, 27th ed; Holland et al., Cancer Medicine, 3d ed, p1866)]
Lymphangitis	D008205	[A lymphatic disease characterized by INFLAMMATION of LYMPHATIC VESSELS.]
Lymphatic Abnormalities	D044148	[Congenital or acquired structural abnormalities of the lymphatic system (LYMPHOID TISSUE) including the lymph vessels.]
