On the skin, a sarcoma usually appears as a raised mass that can be red, purple, or brownish-black. It may be irregular in shape, have fuzzy borders, and grow in size over time. Sometimes, the surface of the sarcoma may appear to be ulcerated or ruptured epidermis, accompanied by the presence of bleeding or necrotic tissue.
In soft tissue, a sarcoma tends to appear as a larger lump that is firm and separate from the surrounding normal tissue. It may be painless, but it may also cause localized pain or compression of peripheral nerves and blood vessels leading to appropriate symptoms.
When a sarcoma occurs in the bone, it often causes bone pain and dysfunction in the corresponding area. The bony portion of the sarcoma will show abnormal radiologic manifestations such as bone destruction, fractures, and bone hyperplasia. Sarcomas may also cause swelling and compression symptoms in adjacent soft tissues.
The appearance of a sarcoma is characterized by irregular shape, color variations, blurred borders, and a variety of symptoms in the corresponding area. It is important to note that the appearance of sarcomas may vary in different individuals and different lesion sites. Therefore, once any suspicious lump or abnormality is found on the body, it is recommended to seek immediate medical attention and professional diagnosis. Only through further examination and confirmation of diagnosis by a doctor can an accurate judgment and treatment be made for the specific situation.
