liver tumor: liver tumors have? how classified? 2010-03-12 12:02 PM what liver tumor liver tumor? how classified? the liver is one of the predilection sites of tumor, rare benign tumors, malignant tumors are more direct shift. Primary tumor in the liver cells can produce Faso, bile duct epithelium, xueguan or other mesoderm tissue, metastatic tumors in the majority of metastatic cancer, mostly metastatic sarcoma. according to tumor origin or not, the liver tumors are classified as follows: benign tumor: liver cell adenoma, hepatic duct cell adenoma, adrenal gland tumor remnant left, xueguan tumors, hamartomas, and other, such as the mesoderm tissue benign tumors (lipoma , fibroids, assimilation tumors, etc.). Cancer: (primary tumor), hepatocellular carcinoma, cholangiocarcinoma, remains of adrenal carcinoma, xueguan sarcoma, other sarcoma (metastatic cancer) metastasis metastatic sarcoma. Leukemia or lymphoma infiltration. In the post below, the smaller section of the right lobe of the tail for the party leaves and leaves, both located at the mercy of longitudinal groove between the parties before the leaves in the transverse caudate lobe in the transverse groove after groove. what is a tumor of the liver xueguan? Liver xueguan liver tumor is a rare benign tumor, including the softening of xueguan tumor, xueguan endothelial cells in tumors, aneurysms and sponge-like capillary xueguan xueguan tumor. the most common tumor cavernous xueguan. our so-called ordinary means of liver tumor xueguan cavernous xueguan tumor. it can be produced in any spring, but most found in adults, more common in 30 to 60 years, more women than men. I used to think a single majority, since the advent of ultrasound imaging has the look to the often more. Liver manipulation leaves can be generated to the right lobe were more common. how common are tumors of liver xueguan? Liver xueguan tumor sizes, from tip to head the size of a large, and the larger abdominal cavity can be filled. Most of less than 4cm. However, most reports of up to 60cm, weight 20kg. Diameter = 10cm for those of ordinary complex liver xueguan tumor. Pathological features of liver tumors xueguan Ruohe? Liver xueguan tumor appearance white or blue-violet purple. was not provided may be lobulated. Margin of stability or texture play the sexy dressing. Section shows the cellular or sponge-like, with thrombosis and fibrous scar area, even with calcification or all of the xueguan tumor was calcified. Disease stage as scar tissue, is known as softening of xueguan tumor. Liver xueguan number of tumor types to be divided into what? according to the number of liver xueguan fibrous tissue tumors can be divided into the following four types: (1) xueguan cavernous aneurysm: the cut surface honeycomb, covered with blood, microscopic flash capsule sizes like sinusoids, which is covered by red blood cells, when blood clots form, fibrous tissue between sinusoids separated by fibrous septa within the see a small xueguan and small bile ducts, liver cells occasionally are tightening the rope. Fibrous septa and sinusoidal calcification or thrombus within the vein stone. (2) softening xueguan tumor, its xueguan cavity closed, more fibrous tissue showed degenerative changes in the interval. (3) xueguan endothelial cells in tumors, xueguan endothelial cell proliferation and lively, prone to cause malignant transformation. (4) capillary xueguan liver tumor, xueguan cavity narrow, fibrous tissue and more intervals. what easy to merge the liver tumor disease xueguan? the disease can also merge the liver to soften, liver, focal liver and other organs xueguan jiejie proliferation or liver tumors, pancreatic cystic change. Xueguan liver tumor etiology and pathogenesis Ruohe? Notice incidence of this disease is not very clear so far, the clinical research hospital tentatively found that the number of species probably have the following: (1) deformation after capillary xueguan tissue infections, aroused the capillary xueguan expanded. (2) the bad part of the organization behind the liver, surrounded by xueguan congestion, expansion, the initial form vacuoles. (3) the prolonged nature of the limitations of intrahepatic venous stasis, vein xueguan aroused swollen to form sponge-like expansion. (4), liver hemorrhage, hematoma machine technology, xueguan constitute xueguan expanded after reperfusion. (5) the day after tomorrow is the intrinsic xueguan tumor development, most have a family genetic direction. Cavernous aneurysm pathogenesis xueguan how? Hepatic cavernous xueguan xueguan tumor liver tumor is the most common benign tumor of the liver. Perhaps that can be produced in the liver tumors did all xueguan cavernous xueguan tumor. Virchow in 1863 first statement. Disease progress in the world, the autopsy it was found that 0.4% to 7.4%, can be produced in any spring, especially in mostly 30 to 45 years old, male and female incidence ratio was 1:0.6 ~ 10. the incidence of sites: 151 cases of material, according to statistics, 47.20% right hepatic lobe, left lobe 36.4%, other issues such as tail, side and vice leaves 11.2%, while two lobe involvement 5.2%. Solitary 66.4% to 90%, 10% ~ 33.6% multiple. Liver tumor incidence of cavernous xueguan notice that? Related liver tumors constitute xueguan generation, common fault of many organizations that Shito germ caused the mesoderm xueguan Shito generated when the tissue barrier in embryonic development and very. Liver tissue from the tumor can be seen xueguan cavity expansion, the wall is no smooth muscle, layout and general xueguan also substandard, similar to the error structure of the xueguan. In addition, the capillary xueguan tissue deformation after infection, hepatocytes produce focal cystic expansion of the bad behind xueguan, liver regional blood flow stasis, also may constitute a sponge-like expansion of the xueguan. Other clinical material shows that the liver tumor xueguan close contact with the female hormone. Earlier onset of spring, such as women, gums, skin tumors in pregnancy xueguan of rapid development. how does the liver tumor development xueguan? Will have cancer it? the development of liver tumors xueguan situation, most of the tumor itself through the endless process of expanding xueguan cavity increases. Sinusoidal active expansion of tumor tissues, congestion, liver cell cord compression, atrophy, fibrosis, tumors around the world so clearly, was not as smooth of Health to cancer, common malignant tumor does not produce itself. Endothelioma of liver disease Ruohe xueguan? what are the symptoms? of the disease than rare. Produce more children in the rehabilitation of female common. Xueguan often accompanied by tumors of other organs, specifically skin xueguan disk about 50%. the primary clinical manifestations are hepatomegaly, high excretion of heart failure and multiple skin xueguan tumor anemia. out of proportion to the size of liver failure, liver in heart failure is still swollen after healing, 1 / 3 of patients the jaundice, and liver could be heard even on the xueguan noise, the tumor occasionally spontaneous Link can also be merged plaque. Life threatening liver xueguan endothelioma it? Xueguan endothelioma of liver cytology benign course of liver tumors, but tumor extract, crushed liver and intrahepatic shunt showed a high dynamic pulse emission of 70% of heart failure often makes babies Masquerade born within a few months. Intratumor xueguan cavity is lined with endothelial cells in one or more layers, cavity filled with blood, Link easy to cause birth Masquerade. is, life’s most difficult to dispose of the threat of congestive heart failure and cancer Link. Endothelioma of liver xueguan later development of the natural course of the disease is moving rapidly, then gradually progress, assuming that the lives of children living, the tumor can be completely recession. Xueguan liver tumors clinically symptoms? General, the tumors were more advanced small xueguan asymptomatic, it is not easy to find later, often in the general physical examination or seizure other lesions occasionally found, usually in patients with anxiety and other expressions in the vibrant changing Hene , drinking, Lawton liver infection after feeling minor discomfort, accompanied by epigastric fullness, heating gas and other symptoms. Clinical manifestations of liver tumor xueguan Ruohe? Clinical manifestations of liver xueguan tumor development and tumor location, size, growth rate and the impact on the liver tumor, the resulting complications. the developmental delay, longer course. Type and clinical symptoms of type into hiding. Hiding type: Most of the patients because the tumor is small, asymptomatic, mostly in examination and laparotomy occasionally found. Specially in recent years, progress in the preparation of non-invasive detection rate of increase in seizure. Syndromes with all kinds of symptoms: upper abdominal pain discomfort, anorexia, nausea, vomiting, similar to chronic liver, gallbladder, pancreas, gastrointestinal disease; also tentatively fever, cold, night sweats, similar to liver abscess, tuberculosis, and these can perhaps tumor hemorrhage and thrombosis constitute or infection. Liver tumor extraction of adjacent organs xueguan will show symptoms? Liver xueguan tumor tumor is small, the ordinary will not squeeze adjacent organs. when the tumor can be extracted increases, goes on adjacent organs, showing various symptoms. Such as the extraction of the lower esophagus, stomach, duodenum, will show of hard swallowing, abdominal distention, abdominal pain, belching and other symptoms; extract can cause liver and gallbladder bile effusion, obstructive jaundice, portal pressure squeeze sparked portal, inferior vena venous pressure can cause ascites, pregnant women may affect the clinical mat. the incorporation of liver disease complicated by tumor xueguan what? Liver xueguan tumor does not render a strict merging common disease, but only when the tumor showed hemorrhage Keidanren merged strict disease. Such as the delay of tumor tumor xueguan Link (internal injuries, gross examination, when the emergency temporary mat production, squeezing chest breathing and other domesticated form intra-abdominal hemorrhage and shock. Specially Link spontaneous bleeding is easily misdiagnosed, treatment delays high birth rate of dropouts . intrahepatic bile duct tumor hemorrhage constitute hemobilia corrosion is one of savda hyperlipidemia notice. manifested as right upper abdominal cramps, fever, jaundice, gastrointestinal bleeding. pedicle pedicle can produce changes in the tumor, causing tumor necrosis, suffering grief, fever, prostration. infants and young children can be grouped to increase purpura platelet and fibrinogen-poor disease, sparked fatal bleeding, hemolysis. constitute the first notice of coagulation factor poor tumor blood supply in complex delay, wear and tear, crush and platelet prothrombin and platelets under the influence of some increase in capacity. also be due to the dynamic pulse of intratumoral shunt xueguan, change thy blood increases, the heart of commitment increased, and showed congestive heart strict weak dried liver xueguan birth rate of dropouts tumor what are the characteristics when the raid? majority of those who have syndromes with palpable mass in the upper abdomen, rounded, smooth stability, capsule sexy, no tenderness, moving with respiration and with the liver connected to high and low. ordinary mass in patients with hard, occasionally tumor can be heard on auscultation and conduction of xueguan tone. liver tumor risk to human life xueguan you? xueguan Link spontaneous tumor bleeding is strictly intra-abdominal complications of the birth of such patients is also a notice of dropouts. the patient presented with acute abdominal pain, the Russian contingent, accompanied by shock, because of complex cavernous sinus tumor xueguan inexhaustible tumor presented in xueguan fiber – a result of recurrent blood clots in the large number of fibers once the depletion of White Plains, easy bleeding stopped. born up to 80% of dropouts. Spring smaller Link much higher. a statement of the baby as much as 5 cases of 6 patients have bleeding in 3 cases there is a world born Masquerade. the natural course of liver tumors Ruohe xueguan? the natural course of liver xueguan tumors has still not very clear. but tentatively follow-up patients can be observed to very slow tumor development, followed by the increase in the Spring and Autumn can produce degenerative changes, tumor xueguan embolism, focal tumor necrosis, liquefaction, fibrosis, calcification. xueguan liver tumors are natural Link it? lead to even what United’s announcement? liver xueguan benign liver tumors are rare, natural, longer duration, most patients asymptomatic his life, according to the clinical and related materials, look flash, the liver produces natural xueguan tumor is commensurate with the opportunity to co-rare, but xueguan liver tumors for a variety of notices can also see the common Link for patients with tumors larger than 30cm or the baby easily aroused Link. rarely notice has internal injuries, puncture, abdominal biopsy, weight lifting, pregnancy, when the emergency temporary mat production, Domestic breathing chest compression, etc. these incentives may increase the chance of tumor Link. jiejie liver jiejie liver lesions that can be divided into the following 5 categories: hepatic jiejie-like regenerative hyperplasia, proliferation of hepatic focal jiejie like, kind of partial liver jiejie change, to soften the liver, liver adenoma. This section discusses far as to contain the first three categories. A, like liver jiejie jiejie regenerative hyperplasia of liver-like regenerative hyperplasia (nodular regenerative hyperplasia of the liver; NRH) in 1981 by Strimyer and lshak reports, is a rare disease. jiejie past has called the liver-like change, miliary liver cell Liu Bing, non-softening or softening of the liver jiejie portal pressure. all over the liver with a small surplus of diffuse liver cell derivative jiejie , jiejie surrounded by fibrous tissue without salvation, fibrosis minor or no fibrosis, can soften the difference in the liver. the disease often arising in older patients, childhood-onset, are rare. the literature of this disease often accompanied with other diseases such as rheumatoid arthritis, Felty decomposition Zheng, kidney transplantation, Crohn’s disease and blood diseases, and drugs (such as immunization to stop agents, corticosteroids) and feeding treatment were adulterated cooking oil generated by decomposition of toxic symptoms such as oil. unknown etiology of the disease, Perhaps with the liver can be very healing response against relevant. abdominal mass is a rare clinical manifestation, can produce intrahepatic portal vein may be low, sparked speculation that the liver xueguan Department jiejie twisted deformation results. normal liver function, no jaundice, ascites, low albumin, prolonged prothrombin time and other performance. is not associated with chronic hepatitis B virus infection or liver softening. no merge disease cases, AFP levels in normal range. Fine needle aspiration biopsy in the diagnosis of useless, internal medicine liver edge of the biopsy diagnosis. prognostic common good, but developmental disorders can produce liver cells, hepatocellular carcinoma is also common to report strandings. II-like proliferation of hepatic focal hepatic focal jiejie jiejie like hyperplasia (focal nodular hyperplasia of the liver; FNH) is the Rogers reported in 1981, is a rare benign lesion, previous was named focal soften, focal jiejie of softening, isolated or isolated jiejie proliferative jiejie like regenerative hyperplasia. Spring may be suffering from any of the patients, females, rare (80%). etiology of this disease is unknown. ordinary that is acquired fundamental intrinsic xueguan general, due to liver cell enzyme defects in hormone drugs leaving cells vulnerable to the comfort, pose behind the repair and regeneration lead to bad results. also might be a violation of the very vascular regeneration of liver response. a lot of statements that the disease associated with oral contraceptives, birth control pills that can perhaps like proliferation of liver cells after focal jiejie nutrient probation, is easy to produce oral contraceptives for women-like proliferation of hepatic focal jiejie Link and bleeding, stop taking the pill in most cases or estrogen-like hyperplasia after the increase in hepatic focal jiejie. FNH common for the single jiejie, located in the liver capsule, most multi-jiejie, deep in the liver. jiejie smaller diameter of 1-7cm, divide well but no capsule, yellow brown, hard. jiejie profile center stellate scar-like, from the center separated from the surrounding radiation will jiejie for the proliferation of hepatic focal jiejie characteristics of shape change, and sometimes central scar is not clear, we can see the intricate cross-thin fiber layer. microscope, flash, general layout of the crushed liver, central stellate scar-like including one or several arteries, arterial intima or middle muscle fibers often has very accretive to luminal narrowing or atresia, there is no central vein. fibrous septa of varying sizes to the surrounding scar tissue from the center of radiation, the interval from the proliferation of fibrous liver cells, sinusoids, and Kupffer cells that. jiejie jiejie within and between the bile duct proliferation, and may be inflammatory cell infiltration. Common symptoms of the disease, the majority of larger lesions may have on the liver suffering abdominal discomfort or sadness, intra-abdominal hemorrhage is merge rare disease. jiejie-like proliferation of hepatic focal characteristics of the serum-free identity token flag material, and the detection rely on imaging the first raid. B Super, CT, MRI and other raids may flash lesions uniform, lower density, Centre scar and everything is arterial blood supply, such as performance. for softening without liver, liver function normal, HBsAg and AFP-positive young patients, specially female patients with liver lesions, strokes thinking like hyperplasia of hepatic focal jiejie can be, perhaps, but must be hepatocellular carcinoma, liver cell adenoma and other phase identification. parting using a variety of seizure may progress in imaging diagnostic accuracy. pathologic diagnosis must rely on raids, but not the initiative biopsy. the disease is not malignant direction lesions can have even greater risk of joint bleeding. diagnosis of hepatic focal asymptomatic clear jiejie like hyperplasia, lesions can closely scrutinize changes, such as lesions increase or less than her inability to identify with hepatocellular carcinoma, the possible surgery . If surgical resection taboo card or not, feasible artery embolization for treatment. Third, some jiejie degeneration of liver (partial nodular transformation of the liver) Liver section jiejie degeneration, also known as jiejie transformation, is also a rare disease. jiejie generated in the around the hepatic portal, portal pressure can probably sparked. other parts of the liver is normal or atrophy, normal liver function. Fine needle aspiration biopsy in the diagnosis of no good. etiology of this disease is unknown. hyperplasia of hepatic focal hepatic focal jiejie jiejie hyperplasia is a benign lesions, but not benign tumors. Since 1958, Edmondson is clearly from the pathology has been stated more Europe, Japan and China’s representation less. the cause is unknown, more common in women, but with the oral contraceptive medicine without close contact, can also be produced in children. the clinical meaning of the primary disease and liver cancer is identified. pathologic changes: there were mostly single, 20% were multiple. the point clear in liver tissue around the fibrous capsule form pressure atrophy , sizes, ranging from 1 ~ 2cm, smaller than the adenoma. jiejie like oozing lesions from the liver constitutes, in addition to jiejie like proliferation, the softening of the false and liver lobule is no different. may have fibrous interval, radiating from the middle to distal extension of the lesion separated. more produced in the liver capsule, deep rare, mass memory in the bile duct and liver macrophages (rupffer cell) to its characteristics. without clinical symptoms specifically, more than occasionally found. can be with abdominal mass, the majority of cases the bleeding can be spontaneous Link. 2 CT scan performance, low-density or isodense was changed. strengthened, for high density, such as density or low density range, the primary condition for its blood supply and the sub, there is fibrous scar sideways when the heart can be seen radiating from the center to the edge of the low-density diffuse diffraction features for image.
