Anemic infarction of the kidney develops in blockage of some of the branches of renal areteriya - obiknovino of embolism, resulting in ischemia occurs with subsequent necrosis of the renal parenchyma in the relevant section. It is a coagulation necrosis, presented in a section of the body with preserved structure in which the visible shadows of glomeruli and tubules. In cells lacking nuclei tubes and homogenized cytoplasm, intense pink colored XE. Disappear cellular details can be seen only vaguely delineated cell borders. Morphological features of necrosis are different phases of nuclear fission: f ission: homogenization (compaction) of the nuclear chromatin - karyopycnosis, karyopycnosis, degradation of nuclei presented in the form of pellets - karyorrhexis and complete disappearance in necrotic cells - karyolysis. Affected cell and tissue structures are homogenized granular cytoplasm and stained more intensely than eozina. Around the area of necrosis is hiperemichnohemoragichnata hiperemichnohemoragichnata area consisting of dilated blood vessels and bleeding. Near it there is segmented shaft of leukocytes, which may be missing in early stages. Adjacent renal tissue is found with a fully preserved structure.

It is for anemic infarction due to obturation of the thrombus or thromboembolism artery in the brain. Necrosis is kolikvatsionen type, characteristic of cells and tissues poor in protein and rich in water and lipids. When hypoxia occurs the death of brain cells, which is manifested by "softening" of brain matter, etc. encephalomalacia. Microscopy in the area of necrosis is seen stretch of pale pink colored, homogeneous, structureless granular matter with a view or as a single thread veins. Gangliyni and glial cells, and nevrofibrili not observed. On the border with preserved tissue are very large cells with bright nuclei and sometimes piknotichni swollen, vacuolated cytoplasm, which detect lipids and brown pigment / hemosiderin. The same is formed f ormed by the disintegration of erythrocytes in the hearth of necrosis and their phagocytic glial cells. These cells are ingested and dissolved lipids of myelin sheath. They are marked as lipofagi (psevdoksantomni cells) and cells derived from mikrogliyata. When staining for lipids in Sudan III kriostatni cuts on their cytoplasm are stained yellow-orange. If fatalities occur after receiving the attack (stroke), the process of necrosis ends with the formation of glial scar formation or a pseudocyst. Years later when an autopsy can be found f ound psevdokistata attesting spent cerebral infarction.

95. Carcinoma Renis ( hypernephroma ). Renal cell carcinoma originates from the seminiferous epithelium and is localized mainly in korata.Toy represents 80% to 85% of all primary malignant tumors of the kidney and 2% to 3% of all malignant neoplasms in adults. It occurs most frequently in the sixth - seventh decade and is twice as frequent in mazhete.Svetlokletachniyat mazhete.Svetlokletachniyat carcinoma is the most common type t ype and is 70% to 80% of all kidney cancers. The bulk is made up of cells with pale granular cytoplasm rich in glycogen and lipids, which give a yellowish color macroscopic tumor there, because his likeness with adrenal gland and its previous name hypernephroma. hypernephroma. Nuclei of light cells are small, round and hiperhromni, mostly located in the center of kletkite.Granuliranite cells resemble the seminiferous epithelium have small round nuclei and granular cytoplasm pink. The t umor has nest building, there are also atsinarni structures surrounded by thin bands of connective tissue and thin-walled blood vessels, which are due to hemorrhage and necrotic areas.

Hepatocellular cancer predsavlyava 5.4% of all malignant tumors in humans as the frequency varies in different parts of sveta.Razvitieto is related largely to infection by hepatitis B and hepatitis C viruses. Macroscopically, Macroscopically, the tumor has three forms: can be a single node , multifocal or dif fuse growing. In well differentiated forms its cells reproduce and form a liver gredichki zhlezistopodobni zhlezistopodobni strukturi.Te are large, polygonal with acidophilic cytoplasm and large hiperhromni yadra.V them can be found zhaltozelenikav bile pigment. In low differentiated cancer cells are large, multi .. Stromal tumor is scarce and is represented only by sinusoidal vessels. Histology of hepatocellular carcinoma is quite diverse and, depending on cell arrangement the following types: t ypes: - Trabecular where atypical hepatocytes are arranged as trabeculae and gredichki with different orientations. - Atsinozen (psevdoglandularen) with formation of kanalikuli zhlezistopodobni zhlezistopodobni or structures whose lumen can sometimes be found bile. - Clear-option when tumor cells are rich in glycoge gl ycogen n and lipids.

100. “Mastopathia chronica fibrosa cystica” cystica”. Fibrokistichnata breast disease is hormonally driven process resulting in hiperestrogenemiya. hiperestrogenemiya. Violation occurs in the t he ratio between connective and epithelial components of breast cancer. The process refers to mamarnata dysplasia. It consists in marked expansion of periduktalnata perilobularnata and connective tissue that is coupled with hyperplasia h yperplasia of ductal and lobular epithelium and formation of single or multiple cysts. Lining the cysts is upholstered single-breasted or double-breasted cube, often epithelial cells have acidophilic cytoplasm, similar to the epithelium of sweat glands - case for hidroadenoidna / apocrine / epithelial metaplasia. There are sections vatrekistichni papillary growths of epithelial / ductal papilomatoza /. The contents of the cysts is a homogeneous pink-colored fabric with eozina. Sometimes, there is atypical lobular hyperplasia, which resembles the cytological carcinoma in situ, but the cells do not fill more than 50% in atsinite lobula.Tazi hyperplasia is a risk of developing in situ or invasive carcinoma. Another element of fibrokistichnata disease can be sclerotic adenoza.Tya is characterized by proliferation of roofing and mioepitelni epithelial cells in small ducts located back to back with significant stromal fibrosis, which forces them. Overgrowth O vergrowth of scar tissue pressing on atsinite lumens and channels and they look as solid strands of cells. Differential diagnosis of invasive carcinoma is difficult. diffi cult.

103. Carcinoma papillare gl. тhyreoideae
Thyroid cancer has four main histological types: t ypes: papillary carcinoma / 75% -85% of cases / follicular carcinoma / 10% to 20% / , medullary carcinoma / 5% / and anaplastic carcinoma / less than 5%. . papillary cancer may be solitary or multifocal type. Macroscopically can be encapsulated or have i nvasive growth to surrounding tissues. Histological type is characteristic of the nuclei of cells constituting the tumor. Their chromatin is finely dispersed and they look optically transparent "ground glass" papillary structures are present, although some tumors are largely composed of follicles. These follicular variants biologically related as papillary tumors if they have h ave previously described nuclei in vid.V papillary structures can be seen concentric laminar calcified structures, denoted as psamomni cells..
