Liver angiosarcoma smooth muscle lipoma

　　1. Etiology

　　The etiology is very complex and is determined by a variety of factors. Like other benign tumors, the internal and external factors are important conditions for the occurrence of liver angiosarcoma smooth muscle lipoma.

　　2. Pathogenesis

　　Liver angiosarcoma smooth muscle lipoma is a benign liver tumor mainly composed of adipose tissue. The typical ones include three histological components: smooth muscle, blood vessels, and mature fat cells. Angiomyolipoma is more common in the kidneys, while it is rare in the liver, however, there is a close relationship between the two. Roberts et al. reported that among 50 cases of renal angiosarcoma smooth muscle lipoma, 5 cases were accompanied by liver angiosarcoma smooth muscle lipoma, indicating that the incidence of liver angiosarcoma smooth muscle lipoma in the renal angiosarcoma smooth muscle lipoma population is relatively high.

　　After the tumor grows, it may show symptoms such as discomfort and pain in the upper right quadrant of the abdomen. AML is a benign tumor of mesenchymal origin, most commonly found in the kidneys, and is related to tuberous sclerosis to some extent. The occurrence of AML in the liver accounts for only 5% to 10%, with solitary occurrence being common, and the relationship with tuberous sclerosis is not as obvious as that in kidney AML. AML in the liver is common in middle-aged and young women, and it is prone to bleeding when the tumor is large. AML consists of three components: mature adipose tissue, smooth muscle cells, and tortuous thick-walled blood vessels, mixed in different proportions, among which the fat component can account for 10% to 90%.

　　The mass of AML has no capsule, but the edge is generally clear. The CT appearance depends on the proportion of various tissue components within the lesion. The diagnosis mainly relies on the detection of fat, and the presence of vascular shadows in the fat component is more diagnostically significant. Enhanced scanning shows that the tumor is significantly enhanced in the arterial and portal venous phases. When the fat content is low, it may be masked by surrounding enhancement. Unenhanced and thin-section scanning are helpful for detecting fat. Some AMLs may appear pseudo-aneurysms, which are significantly dilated thick-walled malformations under the microscope. The CT appearance is

　　Both men and women can be affected by this disease, which usually has a long history. Clinically, there may be no discomfort, and when the tumor grows, it may show discomfort in the upper right abdomen and pain. The etiology is very complex and is determined by multiple factors. Hepatic hemangioleiomyolipoma, like other benign tumors, is an important condition for the occurrence of tumors caused by both intrinsic and extrinsic factors.

　　Deepening the understanding of this disease has certain guiding significance for the clinical treatment of liver tumors.

　　1. Patients with lipomas must pay attention to active physical exercise in their daily life. If symptoms such as abdominal mass, weight loss, fatigue, and weakness are observed, early examination and timely treatment should be carried out.

　　2. According to traditional Chinese medicine, this disease often originates from emotional disharmony, so it is crucial to face everything positively and optimistically, treat various things correctly, relieve anxiety and tension, and avoid emotional injury.

　　3. Patients with lipomas should also pay attention to their light diet, eat less high-fat and high-cholesterol foods, eat more vegetables and fruits, keep the bowels smooth, and not eat too much. It is better to be seven or eight parts full, eat less beef, mutton, pork, and dog meat, and avoid greasy, thick, strong wine, and spicy fried foods. It is better to eat light and nutritious foods.

　　Patients with lipomas can take some drugs to reduce fat and promote fat metabolism, such as alginate disodium, Lipibid, evening primrose oil capsules, salvianolic acid, inosine, adenosine triphosphate, etc., or drink hawthorn tea regularly to reduce fat accumulation in the body.

　　1. CT:Hepatic hemangioleiomyolipoma manifests as a well-defined, homogeneous mass lesion with intact edges on unenhanced CT scans, containing a lower density area with CT values less than -30Hu within the low-density mass. After enhancement, the lower density area does not show enhancement effect, and CT can also determine the size and location of the mass.

　　2. Hepatic Artery Angiography:Since one of the components of angioleiomyoma is blood vessels, angiography through the hepatic artery can show the tumor blood vessels and make a diagnosis. When angioleiomyoma is subjected to hepatic artery angiography, it is manifested as a multi-vessel mass within the liver, with abundant new blood vessels, with or without arteriovenous shunting, and tumor staining in the substance phase. The boundaries are clearly displayed, and there is no accumulation of iodine oil in the mass during iodine oil hepatic artery angiography and embolization.

　　3. B-ultrasound:Under B-ultrasound, it can be seen that the mass has clear boundaries, strong echo, low echo, or mixed echo, and the echo within the mass is uneven. However, according to world literature reports, there has not been a diagnosis of angioleiomyoma by B-ultrasound. The main reason is that the manifestation of the disease is similar to that of other benign tumors in the liver, and ultrasound examination does not have specificity.

　　1. Foods that are good for angioleiomyoma patients

　　Low-fat diet. Patients should eat more fresh vegetables and fruits in daily life to enhance their resistance to the disease. In particular, they should eat more fresh vegetables and fruits rich in vitamin A, carotene, and vitamin C, as well as foods containing vitamin E. Diversify each meal with a variety of foods, try to eat several types of food, and learn to plan a diet that includes five types of food.

　　2. Foods that should not be eaten by angioleiomyoma patients

　　Avoid eating fried, salted, cola, hamburgers, and other foods. Eat less greasy, spicy, and other irritant foods.

　　1. Treatment

　　Since angioleiomyoma is a benign tumor of the liver, it generally has no tendency to malignancy. Therefore, if the diagnosis can be indicated or clearly diagnosed before surgery, conservative treatment can be adopted instead of surgical resection. Although the incidence of angioleiomyoma is low, with the popularization of CT and B-ultrasound and other examination methods, the detection rate of the disease will be improved. In addition, with the wide application of interventional radiology, interventional embolization treatment after angiography is also an effective treatment method.

　　2. Prognosis

　　After clear diagnosis, treatment can be carried out with a good prognosis.
