Physician: A malformation tumor is a substantial occupying lesion, a type of lipoma, consisting of thick-walled blood vessels, smooth muscle and mature adipose tissue, and can develop singly or in multiple cases. Usually, ultrasound and CT examinations have a high rate of localization and qualitative diagnosis of misshapen tumors. Malformation tumor, although benign, has to be surgically removed and only the pathological diagnosis after surgery is accurate. It may turn cancerous although it does not metastasize recently and is also destroying normal organ tissues continuously. It is also a psychological burden to have an extra abnormal thing in the body. That is why surgery is necessary.
