| 영문 | coagulation necrosis | 한글 | 응고괴사 |
|---|---|---|---|
| 설명 | 세포의 죽음을 나타내는 형태학적 변화로서 괴사부위가 응고한 상태로 있는 것. 괴사세포는 호산성 덩어리로 보이며 적어도 수일간 세포의 기본 윤곽이 보존되기 때문에 조직구조를 식별할 수 있다. 대표적으로 허혈괴사를 들 수 있다. 경색과 허혈에 의한 저산소증시 심장근이나 콩팥에서 관찰되거나 전기 및 수은중독시 콩팥의 요세관에서 관찰되는 것으로 단백의 변성 후 남아있기 때문이다. 세포의 윤곽이 남아 있어 원래 조직의 구조를 형태학적으로 인식할 수 있는 것이 특징이다. |

| 영문 | caseation necrosis | 한글 | 치즈괴사, 건락괴사 |
|---|---|---|---|
| 설명 | 조직이 치즈와 같이 건조하고, 형태가 없는 덩어리로 변화하는 것으로 결핵감염 병터에서 볼 수 있는 독특한 괴사의 하나이다. |

| 영문 | solid tumor | 한글 | 고형종양 |
|---|---|---|---|
| 설명 | 세포로 꽉 찬 종양을 말함. 백혈병 등의 혈액암과 같이 형태를 취하지 않고 액체인 상태의 암과 대조되는 용어로서 단단한 덩어리로 구성된 악성종양이다. 대부분의 종양이 이에 해당한다. 특히 표피조직에서 기원한 종양을 말한다. |

| 영문 | ulcerating tumor | 한글 | 궤양성 종양 |
|---|---|---|---|
| 설명 | 종양의 표면에 궤양이 발생하는 것. 대개, 매우 빨리 자라는 종양에서 혈류 공급이 종양세포의 자라는 속도를 감당하지 못해 종양중심부 조직이 괴사에 빠져 궤양을 형성하는 경우가 많다. 육안으로 보면 빨갛고, 열이나며, 지저분해 보인다. |

| 영문 | brain tumor | 한글 | 뇌종양 |
|---|---|---|---|
| 설명 | 뇌종양이란 뇌와 뇌조직에서 생긴 종양을 지칭하는 말이다. 그러나 대개 넓은 의미로 사용할 경우에는 머리뼈속의 공간인 두개강속에 생기는 모든 종양을 이르는 말로 사용된다. 뇌종양은 한정된 공간인 두개강에서 발생하므로 종양이 그다지 크지 않아도 정상적인 조직을 압박하게 되고, 두개강내의 압력을 높인다. 이런 특징에 의해서 뇌종양의 증상은 다른 종양과 달리, 종양 그 자체의 증상보다도 두개내압상승과 정상조직의 압박에 의한 증상이 많다. 두개내압(뇌압)의 상승에 의한 증상으로는 두통, 구토등이 있으며, 지속적인 뇌압상승에 의해서 유두부종(papilledema)이 관찰되기도 한다. 그리고 정상적인 뇌조직의 압박과 종양이 생긴 부위의 기능의 결합에 뇌의 그 부분에 해당하는 기능의 상실을 보게된다. |

pressure necrosis
| central necrosis | Necrosis involving the deeper or inner portions of a tissue, or an organ or its units. (05 Mar 2000) |
|---|---|
| cerebrocortical necrosis | A noninfectious disease of ruminants characterised by a tissue-thiamine deficiency and by amaurosis and strabismus, followed by recumbency, opisthotonos, and convulsions. Synonym: cerebrocortical necrosis. (05 Mar 2000) |
| retinal necrosis syndrome, acute | <ophthalmology> Mild to fulminant necrotizing vaso-occlusive retinitis associated with a high incidence of retinal detachment and poor vision outcome. (12 Dec 1998) |
| coagulation necrosis | A type of necrosis in which the affected cells or tissue are converted into a dry, dull, fairly homogeneous eosinophilic mass without nuclear staining, as a result of the coagulation of protein as occurs in an infarct; microscopically, the necrotic process involves chiefly the cells, and remnants of histologic elements (e.g., elastin, collagen, muscle fibres) may be recognizable, as well as "ghosts" of cells and portions of cell membranes; may be caused by heat, ischemia, and other agents that destroy tissue, including enzymes that would continue to alter the devitalised cellular substance. (05 Mar 2000) |
| colliquative necrosis | An obsolete term for liquefactive necrosis. (05 Mar 2000) |
| mummification necrosis | A form of gangrene in which the involved part is dry and shriveled. Synonym: cold gangrene, mummification necrosis, mummification. (05 Mar 2000) |
| contraction band necrosis | A microscopic change in myocardial cells in which excessive contraction, associated with elevated intracellular calcium and serum norepinephrine, causes the formation of transverse amorphous band's in the fibres which are then incapable of contracting again. Synonym: contraction band necrosis. (05 Mar 2000) |
| myocardial necrosis | Irreversible destruction of myocardial (heart muscle) cells. (27 Sep 1997) |
| postpartum pituitary necrosis syndrome | <syndrome> Hypopituitarism arising from a severe circulatory collapse postpartum, with resultant pituitary necrosis. Synonym: postpartum pituitary necrosis syndrome, thyrohypophysial syndrome. (05 Mar 2000) |
| cystic medial necrosis | Loss of elastic and muscle fibres in the aortic media, with accumulation of mucopolysaccharide, sometimes in cystlike spaces between the fibres; a disease of unknown cause, which may be inherited and which predisposes to dissecting aneurysms. Synonym: Erdheim disease, medionecrosis aortae idiopathica cystica, medionecrosis of the aorta, mucoid medial degeneration. (05 Mar 2000) |
| progressive emphysematous necrosis | <microbiology> A severe form of gangrene (tissue necrosis) caused by Clostridium infection. Also referred to as necrotising subcutaneous infection. Results in death of the subcutaneous tissues and muscle layers. See: necrotising fascitis. (27 Sep 1997) |
| hepatic necrosis | A severe and rapidly progressive form of hepatitis accompanied by hepatocellular death and the signs and symptoms of hepatic failure. May be a complication of hepatitis B, C or D. (27 Sep 1997) |
| simple necrosis | A stage of coagulation necrosis; the occurrence of a coarsely granular or hyaline change in the cytoplasm, and the lack of a recognizable nucleus, with the general configuration of the dead cells being relatively unchanged. (05 Mar 2000) |
| necrosis | <pathology> The sum of the morphological changes indicative of cell death and caused by the progressive degradative action of enzymes, it may affect groups of cells or part of a structure or an organ. Origin: Gr. Nekrosis = deadness (18 Nov 1997) |
| necrosis bacillus | A species of gram-negative, non-spore-forming bacteria isolated from the natural cavities of man and other animals and from necrotic lesions, abscesses, and blood. (12 Dec 1998) |
