Label	Id	Description
Marchiafava-Bignami Disease	D054319	[A neurodegenerative condition that is characterized by demyelination or necrosis of the CORPUS CALLOSUM. Symptoms include DEPRESSION; PARANOIA; DEMENTIA; SEIZURES; and ATAXIA which can progress to COMA and death in a few months. Marchiafava-Bignami syndrome is seen often in alcoholics but has been found in non-alcoholics as well.]
Marek Disease	D008380	[A transmissible viral disease of birds caused by avian herpesvirus 2 (HERPESVIRUS 2, GALLID) and other MARDIVIRUS. There is lymphoid cell infiltration or lymphomatous tumor formation in the peripheral nerves and gonads, but may also involve visceral organs, skin, muscle, and the eye.]
Marfan Syndrome	D008382	[An autosomal dominant disorder of CONNECTIVE TISSUE with abnormal features in the heart, the eye, and the skeleton. Cardiovascular manifestations include MITRAL VALVE PROLAPSE, dilation of the AORTA, and aortic dissection. Other features include lens displacement (ectopia lentis), disproportioned long limbs and enlarged DURA MATER (dural ectasia). Marfan syndrome is associated with mutations in the gene encoding fibrillin, a major element of extracellular microfibrils of connective tissue.]
Margins of Excision	D000072662	[The edges of tissue removed in a surgery for assessment of the effectiveness of a surgical procedure in achieving the local control of a neoplasm and the adequacy of tumor removal. When the margin is negative or not involved by tumor (e.g., CANCER) it suggests all of the tumor has been removed by the surgery.]
Marijuana Abuse	D002189	[Use of marijuana associated with abnormal psychological, social, and or occupational functioning.]
Masked Hypertension	D059468	[Phenomenon where increased BLOOD PRESSURE readings taken in non-clinical settings (e.g., HOME BLOOD PRESSURE MONITORING) do not replicate in clinical settings.]
Massive Hepatic Necrosis	D047508	[Extensive and rapid death of parenchymal cells in the LIVER, often due to exposure to toxic materials. It is characterized by a soft, flabby, yellow-brown wrinkled, and shrunken liver. It was called "acute yellow atrophy".]
Mast-Cell Sarcoma	D012515	[A unifocal malignant tumor that consists of atypical pathological MAST CELLS without systemic involvement. It causes local destructive growth in organs other than in skin or bone marrow.]
Mastitis	D008413	[INFLAMMATION of the BREAST, or MAMMARY GLAND.]
Mastitis, Bovine	D008414	[INFLAMMATION of the UDDER in cows.]
Mastocytoma	D034801	[A solid tumor consisting of a dense infiltration of MAST CELLS. It is generally benign., A very rare, unifocal tumor with no skin involvement and a non-destructive growth pattern, consisting of mature MAST CELLS.]
Mastocytoma, Skin	D054705	[A variant of cutaneous mastocytosis which occurs as a single lesion usually in infants. It is found mostly in the wrist and trunk and there is no atypical cytomorphology.]
Mastocytosis	D008415	[A heterogenous group of disorders characterized by the abnormal increase of MAST CELLS in only the skin (MASTOCYTOSIS, CUTANEOUS), in extracutaneous tissues involving multiple organs (MASTOCYTOSIS, SYSTEMIC), or in solid tumors (MASTOCYTOMA).]
Mastocytosis, Cutaneous	D034701	[A form of cutaneous mastocytosis that is characterized by a diffuse erythrodermic rash rather than the maculopapular infiltrates seen in URTICARIA PIGMENTOSA., Skin lesions due to abnormal infiltration of MAST CELLS. Cutaneous mastocytosis is confined to the skin without the involvement of other tissues or organs, and is mostly found in children. The three major variants are: URTICARIA PIGMENTOSA; diffuse cutaneous mastocytosis; and SOLITARY MASTOCYTOMA OF SKIN., A form of cutaneous mastocytosis that is characterized by the large fluid-filled lesions.]
Mastocytosis, Systemic	D034721	[A form of systemic mastocytosis in which patients have impaired organ functions due to multifocal infiltrates of pathological MAST CELLS in bone marrow, liver, spleen, gastrointestinal tract, or skeletal system. The cytomorphology shows a low to high grade., A form of systemic mastocytosis in which patients experience no pain. It is characterized by the multifocal mast cell filtrates, mostly in skin and bone marrow (<20% MAST CELLS). It has a low cytomorphological grade., A group of disorders caused by the abnormal proliferation of MAST CELLS in a variety of extracutaneous tissues including bone marrow, liver, spleen, lymph nodes, and gastrointestinal tract. Systemic mastocytosis is commonly seen in adults. These diseases are categorized on the basis of clinical features, pathologic findings, and prognosis.]
Mastodynia	D059373	[Pain in the breast generally classified as cyclical (associated with menstrual periods), or noncyclical, i.e. originating from the breast or nearby muscles or joints, ranging from minor discomfort to severely incapacitating.]
Mastoiditis	D008417	[Inflammation of the honeycomb-like MASTOID BONE in the skull just behind the ear. It is usually a complication of OTITIS MEDIA.]
Maternal Death	D063130	[The death of the female parent.]
Maxillary Diseases	D008439	[Diseases involving the MAXILLA.]
Maxillary Fractures	D008440	[Fractures of the upper jaw.]
