The Anatomy of Angiolipoma:
In the picture above, the left side shows the internal organs; while the right side shows external organs. These are called major organs. Major organ include liver, heart, kidneys, lungs and intestines.
Other minor organs include testicles and spleen. The main difference between these two types of tumors is their location in the body. Liver tumors are located inside the liver. Heart tumors are located outside the heart. Kidney tumors are located inside the kidney. Lung tumors are located outside the lungs. Intestines tumor is located in the small intestine (small bowel).
A typical Angiolipoma:
The most common type of Angiolipoma is the carcinoid type. There are three types of this type: Carcinoids, which means “cancerous” or “tumor causing”. They have a very high rate of recurrence.
They occur when cells grow out of control and start growing into other parts of the body. Carcinoids are usually found in the head, neck, chest and back. The second type is called Pseudocarcinoid, which means “pseudo-cancerous” or “like cancer” They usually do not spread to other parts of the body. They occur when cells change but not enough to form tumors. The third type is called Medullary Carcinoid, which means “center of the liver”. They are only found in the liver and are slow growing. It is not clear what causes these tumors.
The most common symptom of angiolipomas is bleeding, which arises from the blood vessels contained in the tumor. These are referred to as “Petechia” and “Ecchymoses”. Another sign is pain, which occurs in the areas surrounding the tumor.
These are caused by the expansion of the tumor. This can lead to severe pain in the area and, sometimes, respiratory issues. Mood issues can also occur due to constant pain.
Treatment of Angiolipomas:
The treatment of these tumors is very extensive and must be carried out by an experienced medical professional. The first step consists of surgical removal of the tumor, which is then followed by chemotherapy and radiation therapy. Chemotherapy is the use of certain drugs to destroy cancerous cells found in the body.
Radiation therapy is the use of high-energy rays to kill tumor cells. In some cases, these aggressive treatments are not enough; in which case the patient may undergo a liver transplant.
The different types of angiolipomas:
There are several types of this tumor. The most common are:
Carcinoid: It affects about 10% of people with this disease. It is slow growing and has the potential to spread throughout the body. It can also cause ulcers, inflammation and bleeding.
Pseudocarcinoid: It is rare and does not have the potential to spread throughout the body.
Medullary carcinoid: It is also rare and occurs mainly in middle-aged men. It rarely spreads to other parts of the body.
Who gets Angiolipomas?
These diseases affect mainly middle-aged adults, age 30-60. Carcinoids mostly affect men, while medullary carcinoid commonly affects women. It is least likely to occur in people under the age of 20 and over the age of 70. People with a family history of this disease are more likely to get it as well.
