Adenoma of the middle ear is a benign tumor that develops from the epithelium of glandular organs and is a rounded node, clearly delimited from the surrounding tissue.

A median cyst of the neck can form at an early stage of embryonic development – from the 3rd to the 5th week of pregnancy, and is clinically manifested at any age, but most often during periods of intensive growth or during periods of hormonal changes in the body.
Microtropia (monofixation syndrome) can be primary or occur as a result of surgical intervention after correction of a large angle of deviation.
Microsporia is a disease affecting the skin and hair, most often observed in children. Microsporia pathogens are divided into anthropophiles, zoophiles and geophiles by etiology.
Microscopic polyarteritis is a necrotizing vasculitis with damage to small-caliber vessels, associated with antineutrophil cytoplasmic autoantibodies (ANCA); it is widespread with damage to many organs and systems, but the most pronounced changes are observed in the lungs, kidneys and skin. It has been identified as a separate nosological form of systemic vasculitis in recent years and included in the 1992 classification.
Microscopic polyangiitis is a necrotizing vasculitis with minimal or no immune deposits, affecting small vessels (arterioles, capillaries, venules), less often medium-caliber arteries, with necrotizing glomerulonephritis and pulmonary capillaritis predominating in the clinical picture.
Microphthalmos is diagnosed when the length of the anterior-posterior axis of the eyeball is less than normal and is 21 mm in an adult and 19 mm in a one-year-old child.
Micropenis is a term used to describe a penis that is less than 2 standard deviations from the norm in the absence of any other visible pathology associated with underdevelopment of the penis (e.g. hypospadias, hermaphroditism).

Microcytosis is a condition in which red blood cells (red blood cells) in the blood are smaller than normal.

Microcephaly is an extremely severe, incurable pathology characterized by underdevelopment of the skull, insufficient functioning of the brain, dementia and other psychoneurological abnormalities.
Methylenedioxymethamphetamine (MDMA - more commonly known as ecstasy, or Adam, or "E") is an amphetamine analogue. MDMA is usually taken in pill form. It has both stimulant and hallucinogenic properties. Long-term use can lead to dependence.
One of the main functions of the endometrium is to ensure implantation and nidation of the embryo. An important role in this process is played by the maturity of the endometrium, its synchronization with the hormonal background throughout the menstrual cycle.
Methemoglobin, unlike normal hemoglobin, does not contain reduced iron (Fe2+), but oxidized iron (Fe3+), and in the process of reversible oxygenation, oxyhemoglobin (Hb O2) is partially oxidized into methemoglobin (Mt Hb).

This is a very dangerous substance that acts quite quickly and leads to serious consequences, disability and even death.

Methane easily penetrates the blood-brain barrier, affecting the brain, depressing the respiratory organs and the CNS.

Meteorological cheilitis is a disease caused by the influence of meteorological factors (high or low humidity, dust in the air, wind, cold).
Metatypical skin cancer (syn.: basosquamous cancer, mixed cancer, intermediate carcinoma) can develop on unchanged skin, but often occurs against the background of pre-existing basalioma, especially after radiotherapy. The clinical manifestations of metatypical cancer in most cases do not differ from the clinical picture of basalioma and usually correspond to its tumor and ulcerated forms.
Neuroblastoma is one of the most common malignant tumors in children. Neuroblastoma originates from primitive neuroblasts of the sympathetic trunk, most often in the abdomen, less often in the chest and pelvis.

At the beginning of the process, when it is best to treat it, it often looks like a new, ordinary flat mole of irregular shape and does not show itself in any special way. Therefore, melanoma is often detected at later stages, which leads to disappointing results.

Metastases in the rectum are carried throughout the body by the blood and lymphatic systems. For rectal cancer, the source of metastasis is often organs and tissues adjacent to the tumor.
