benign tumor of spleen
Introduction
Introduction to benign tumor of spleen Benign benign tumors mainly include spleen hamartoma, lymphangioma, hemangioma, fibroids, lipoma, etc., and benign benign tumors are mostly single. When the tumor is small, there are no clinical symptoms and signs, which are occasionally found when the spleen is removed or at autopsy. basic knowledge The proportion of illness: the incidence rate is about 0.003% - 0.007% Susceptible people: no special people Mode of infection: non-infectious Complications: spleen rupture shock
Cause
Causes of benign tumors of the spleen
Causes
According to the different organizations of origin, they are mainly divided into three types.
Spleen hamartoma:
Very rare, the incidence rate in splenectomy is about 3/200,000, less than 10 cases reported in China, its composition is consistent with the normal composition of the spleen, also known as spleen and spleen, spleen nodular proliferation, also known as the literature Spleen deficiency tumor, the cause of which is the early developmental abnormality of the spleen embryo base, which makes the proportion of the normal components of the spleen disorder. The tumor is mainly composed of dysfunctional spleen sinus, the spleen corpuscle is rarely seen, and the spleen trabeculae is absent. Or occasionally visible, the gross view of the tumor is circular or elliptical, the boundary is clear, no capsule, grayish white and light red. The spleen hamartoma in the literature has both single and multiple reports.
Spleen hemangioma:
It consists of a sponge-like dilated blood vessel, also known as cavernous hemangioma, splenic cavernous hamartoma, spleen peripheral vasodilator hemangioma and splenic aneurysm disease, which is caused by abnormal fetal growth of the spleen vascular tissue. rare.
Splenic lymphangioma:
It is common in 3 benign tumors, accounting for 2/3. The spleen lymphangioma is composed of cystic dilated lymphatic vessels, also known as splenic cavernous lymphangioma or spleen cystic lymphangioma, which is based on congenital locality. Dysplasia, obstructed lymphatic vessels continue to expand.
Prevention
Prevention of benign tumor of spleen
1. Develop good habits, stop smoking and limit alcohol. Smoking, the World Health Organization predicts that if people no longer smoke, after five years, the world's cancer will be reduced by one-third, and secondly, no alcohol. Smoke and alcohol are extremely acidic and acidic substances. People who smoke and drink for a long time can easily lead to acidic body. No prior information
2. Don't eat too much salty and spicy food, don't eat food that is overheated, too cold, expired and deteriorated; those who are frail or have certain genetic diseases should eat some anti-cancer foods and high alkali content as appropriate. Alkaline foods maintain a good mental state.
Complication
Spleen benign tumor complications Complications spleen rupture shock
Individual cases, especially splenic hemangioma, may have spontaneous spleen rupture due to their relationship with arteriovenous traffic, causing shock and death from abdominal hemorrhage.
Symptom
Symptoms of benign tumor of the spleen Common symptoms Hemorrhagic tendency Anxious upper abdominal mass and bloating heart palpitations Gastric sputum full calcification
Benign benign tumors often have single hair, different sizes and different forms. Because of their hidden symptoms, clinical diagnosis is difficult. They are often found by chance during autopsy or laparotomy. In a few cases, the left upper abdominal mass is caused by spleen, pain, and fullness after eating. Inflammation, shortness of breath and palpitations, or due to anemia and bleeding tendency caused by hypersplenism, found that some cases were found by clinical examination due to cystic changes and calcification.
Examine
Examination of benign tumor of spleen
X-ray examination of the abdomen can reveal signs of spleen enlargement and local compression, but it is not specific. The fundus and large bends are seen after the meal. The transverse spleen is seen to be pushed to the right after the sputum enema. The lateral kidney can be seen to be pushed downward under venography. B-ultrasound can be used as the first choice for spleen tumors. It can show the size of the spleen, distinguish the solidity of the tumor, understand the envelope of the tumor, and have a high diagnosis of the spleen tumor. Value, color Doppler ultrasonography can understand the blood supply inside the tumor, and help to judge the nature of the tumor. CT is the most valuable imaging examination for the diagnosis of spleen tumor, which can accurately provide the size and shape of the tumor. The relationship between the surrounding organs can be found in small tumors of about 1 cm. It is also possible to know more about other organs in the surrounding organs. The diagnostic value of MRI for spleen tumors is similar to that of CT. There are few clinical applications, selective celiac artery. Contrast can understand the distribution of spleen vascular branches, and can judge its nature according to the number of tumor blood vessels, compression, interruption and neovascularization, and diagnose and spleen tumors. Do not diagnose is of great value.
B-ultrasound or CT-guided fine needle aspiration biopsy of the spleen, due to the influence of the patient's breathing, positioning is more difficult, and can be complicated by intra-abdominal hemorrhage or spleen pseudoaneurysm, the risk is greater, should be carefully selected.
Laparoscopy can observe the lesions on the surface of the spleen. At the same time, it can carry out angiography and biopsy under the guidance of the spleen. It has certain value for the diagnosis of spleen diseases or the etiology of splenomegaly.
Diagnosis
Diagnosis and differentiation of benign tumor of spleen
According to the medical history, clinical symptoms and imaging examination, it can be differentiated from primary malignant spleen tumor or metastatic spleen tumor. It is worth mentioning that the diagnosis of most spleen benign and malignant tumors depends on surgical exploration and pathological organization. Learning to check, so in the selection of imaging examinations, you do not have to be all-inclusive, after the initial diagnosis of B-ultrasound and CT, you can consider surgical exploration.
Benign spleen tumors should be differentiated from parasitic spleen cysts, primary malignant spleen tumors and metastatic spleen tumors. Parasitic spleen cysts are often cystic, X-ray examination is easy to see cystic wall calcification, blood picture shows eosinophilic Granulocyte proliferation and specific serum test positive can be diagnosed, primary malignant tumors often have more prominent symptoms than benign tumors, rapid growth of tumors, systemic weight loss and other factors are helpful to identify, metastatic splenic tumors often originated from lung cancer, breast cancer , malignant melanoma and spleen surrounding organ cancer, etc., as long as detailed examination, it is not difficult to find the performance of primary cancer and multiple organ damage.
