Label	Id	Description
Metatarsalgia	D037061	[Pain in the region of the METATARSUS. It can include pain in the METATARSAL BONES; METATARSOPHALANGEAL JOINT; and/or intermetatarsal joints (TARSAL JOINTS).]
Metatarsus Varus	D000070592	[A foot anomaly in which the forefoot (METATARSUS) is angled inward relative to the heel.]
Methemoglobinemia	D008708	[The presence of methemoglobin in the blood, resulting in cyanosis. A small amount of methemoglobin is present in the blood normally, but injury or toxic agents convert a larger proportion of hemoglobin into methemoglobin, which does not function reversibly as an oxygen carrier. Methemoglobinemia may be due to a defect in the enzyme NADH methemoglobin reductase (an autosomal recessive trait) or to an abnormality in hemoglobin M (an autosomal dominant trait). (Dorland, 27th ed)]
Metrorrhagia	D008796	[Abnormal uterine bleeding that is not related to MENSTRUATION, usually in females without regular MENSTRUAL CYCLE. The irregular and unpredictable bleeding usually comes from a dysfunctional ENDOMETRIUM.]
Mevalonate Kinase Deficiency	D054078	[Autosomal recessive disorder caused by mutations in the mevalonate kinase gene. Because of the mutations cholesterol biosynthesis is disrupted and MEVALONIC ACID accumulates. It is characterized by a range of symptoms, including dysmorphic FACIES, psychomotor retardation, CATARACT, hepatosplenomegaly, CEREBELLAR ATAXIA, elevated IMMUNOGLOBULIN D, and recurrent febrile crises with FEVER; LYMPHADENOPATHY; ARTHRALGIA; EDEMA; and rash.]
Microaneurysm	D000071071	[Aneurysm of the MICROVASCULATURE. Charcot-Bouchard aneurysms are aneurysms of the brain vasculature which is a common cause of CEREBRAL HEMORRHAGE. Retinal microaneurysm is an early diagnostic sign of DIABETIC RETINOPATHY.]
Microcephaly	D008831	[A congenital abnormality in which the CEREBRUM is underdeveloped, the fontanels close prematurely, and, as a result, the head is small. (Desk Reference for Neuroscience, 2nd ed.)]
Micrognathism	D008844	[Abnormally small jaw.]
Micronuclei, Chromosome-Defective	D048629	[Defective nuclei produced during the TELOPHASE of MITOSIS or MEIOSIS by lagging CHROMOSOMES or chromosome fragments derived from spontaneous or experimentally induced chromosomal structural changes.]
Microphthalmos	D008850	[Congenital or developmental anomaly in which the eyeballs are abnormally small.]
Microsatellite Instability	D053842	[The occurrence of highly polymorphic mono- and dinucleotide MICROSATELLITE REPEATS in somatic cells. It is a form of genome instability associated with defects in DNA MISMATCH REPAIR.]
Microscopic Polyangiitis	D055953	[A primary systemic vasculitis of small- and some medium-sized vessels. It is characterized by a tropism for kidneys and lungs, positive association with anti-neutrophil cytoplasmic antibodies (ANCA), and a paucity of immunoglobulin deposits in vessel walls.]
Microsporidiosis	D016881	[Infections with FUNGI of the phylum MICROSPORIDIA.]
Microstomia	D008865	[A congenital defect in which the mouth is unusually small. (Dorland, 27th ed)]
Microtrauma, Physical	D000070617	[Small injuries caused by external force applied to the body including bones, muscles, nerves and tendons.]
Microvascular Angina	D017566	[ANGINA PECTORIS or angina-like chest pain with a normal coronary arteriogram and positive EXERCISE TEST. The cause of the syndrome is unknown. While its recognition is of clinical importance, its prognosis is excellent. (Braunwald, Heart Disease, 4th ed, p1346; Jablonski Dictionary of Syndromes & Eponymic Diseases, 2d ed). It is different from METABOLIC SYNDROME X, a syndrome characterized by INSULIN RESISTANCE and HYPERINSULINEMIA, that has increased risk for cardiovascular disease.]
Microvascular Rarefaction	D000073436	[The reduction in density of the MICROVASCULATURE.]
Middle Lobe Syndrome	D008878	[Atelectasis of the right middle pulmonary lobe, with chronic pneumonitis. (Dorland, 27th ed)]
Migraine Disorders	D008881	[A class of disabling primary headache disorders, characterized by recurrent unilateral pulsatile headaches. The two major subtypes are common migraine (without aura) and classic migraine (with aura or neurological symptoms). (International Classification of Headache Disorders, 2nd ed. Cephalalgia 2004: suppl 1)]
Migraine with Aura	D020325	[A subtype of migraine disorder, characterized by recurrent attacks of reversible neurological symptoms (aura) that precede or accompany the headache. Aura may include a combination of sensory disturbances, such as blurred VISION; HALLUCINATIONS; VERTIGO; NUMBNESS; and difficulty in concentrating and speaking. Aura is usually followed by features of the COMMON MIGRAINE, such as PHOTOPHOBIA; PHONOPHOBIA; and NAUSEA. (International Classification of Headache Disorders, 2nd ed. Cephalalgia 2004: suppl 1)]
