An angiolipoma is a non-cancerous tumour made up of fat and small blood vessels. Most angiolipomas occur just under our skin where they feel like a soft lump.
The most common symptom associated with angiolipoma is pain.
At present, doctors do not know what causes a person to develop an angiolipoma.
No, angiolipoma will not turn into a cancer over time. However, it is not uncommon for a person to develop more than one angiolipoma.
The first diagnosis of a lipoma may be made after a small sample of tissue is removed in a procedure called a biopsy. Surgery can then be performed to remove the entire tumour.
Under the microscope, an angiolipoma is made up of fat cells called adipocytes. Small blood vessels, some of which contain blood clots, are also found throughout the tumour. Most lipomas are surrounded by a thin layer of tissue called a capsule, which keeps the tumour separated from the surrounding tissues. The capsule also makes these tumours relatively easy for your surgeon to remove.
