Angiolipoma
Introduction
Introduction to angiolipoma Angiolipoma (Agiolipoma) is a lobulated adipose tissue tumor with obvious capsule, which is characterized by intratumoral vascular hyperplasia and often pain. The disease occurs in the forearm and waist, single or multiple, often symmetrically distributed. Generally slow growth, about 1/3 of patients have varying degrees of fatigue, fatigue and obvious backache. More common in the upper limbs and trunk subcutaneous, even in the internal organs, intracranial and spinal canal. Tumors are more common in young men. The growth is quite slow and generally requires no treatment and can be surgically removed if necessary. basic knowledge The proportion of illness: 0.0003% Susceptible people: more common in young men Mode of infection: non-infectious Complications: hepatic cyst
Cause
Angiolipoma etiology
Dietary factors (25%):
Excessive drinking, often eating fat, animal gut, scaleless fish or egg yolk. Because eating too much fatty products, high cholesterol food, can cause spleen and stomach damp heat, phlegm and endogenous, transport disorders, that is, too much new fat tissue, so that the body's excessive fat cells are heterogeneous, hard.
Psychological factors (30%):
People who are overworked, irritated, and often angry. Because of liver qi stagnation, poor blood and meridians, the normal adipose tissue and blood can be intertwined, and connective tissue can be wrapped into fat cells for a long time to form lipoma.
Bad living habits (25%):
I often stay up all night and think about people with too many problems. Because the spleen and stomach are injured, the spleen loses health and the yin and yang are dysfunctional, so that the body's ability to decompose fat is reduced, and the original fat tissue and newborn fat can not be properly arranged, forming an abnormal adipose tissue, that is, "lipoma."
Prevention
Angiolipoma prevention
If the presence of an angiolipoma has been found, anxiety should be avoided. If the tumor is large, there is compression, and if necessary, surgical resection is performed along with pathology. At the same time, pay attention to maintaining a good mentality, active physical exercise, good working hours and eating habits, which can improve resistance.
Complication
Angiolipoma complications Complications liver cyst
1, vascular lipoma rupture: can cause acute abdomen or internal bleeding symptoms.
2, thrombocytopenia and low fibrinogenemia: a small number of patients often cause this disease due to coagulation disorders.
3, liver enlargement: when the hemangioma grows up, it will cause liver enlargement.
4, liver cyst: about 10% of patients can be complicated by liver cysts.
Symptom
Angiolipoma symptoms common symptoms lipoma nodules
1. The disease occurs in the forearm and waist, similar to lipoma.
2. Single or multiple, often symmetric distribution, skin lesions are divided into 3 types: nodular, plaque, strip and diffuse infiltration, the texture is slightly harder than lipoma, diameter <2cm, often under the skin, there are Mild tenderness.
3. Generally slow growth, increased to a certain extent, that is, stop growing, no rupture and metastasis, about 1/3 of patients have varying degrees of fatigue, fatigue and obvious backache, visceral examination without abnormalities.
Examine
Angiolipoma examination
Histopathology: The tumor tissue has obvious capsule, which is lobulated, the cut surface is yellow, and the margin is reddish due to vascular components. In addition to mature fat cells, there are hyperplastic capillaries in the tissue, and connective tissue along the septum from the capsule. Growing to the center, endothelial cells proliferate lumen stenosis, some can only accommodate 1 to 2 red blood cells or completely occluded, there are often transparent thrombus in the cavity, collagen fibers in the interstitial are often homogenized, lightly stained with red, no obvious Inflammation.
Diagnosis
Diagnosis and identification of angiolipoma
diagnosis
According to the clinical manifestations, the characteristics of skin lesions and histopathological features can be diagnosed.
Differential diagnosis
1. Lipoma: Capillary endothelial cells rarely proliferate, and there is no fibrinous thrombus in the blood vessels. The skin lesions of patients with lipoma generally do not have tenderness. Microscopically, they are mainly mature fat cells. There are not many blood vessels in the tumor, and there is little endothelium.
2. Hemangioma: There is no fluctuation in hemangioma, and there is no fat cell in the tumor tissue. Cellular angiolipoma needs to be differentiated from Kaposi sarcoma. Kaposi sarcoma can also have intravascular capillary thrombosis at the edge of the tumor, but there are no mature fat cells. Multiple angiolipomas are clinically difficult to differentiate from neurofibromatosis and rely on pathological examination.
3. Skin cysticercosis: The cyst is not divided into leaves, and the cysticercosis can be found.
