Soft tissue tumor

Symptoms| Lump, pain
Types| Noncancerous (benign) or cancerous (malignant)
Diagnostic method| Medical imaging, biopsy
Prognosis| Varies with type
Frequency| Common, ~3,000 new cases per 1 million population annually[1]

A soft tissue tumor is an abnormal growth of tissue in soft tissue.[1] Signs and symptoms include pain and a slow or rapidly growing swelling.[1] Age, gender and site of the tumor can provide clues to the type of tumor.[1] Lipomas are typically painless and rarely occur in the hands and feet or in children.[1] Angiolipomas generally occur as a painful lump in young men and angioleiomyomas typically present as a painful lump in the lower leg of middle-aged females.[1] Around 50% of vascular tumors occur in individuals younger than 20-years of age.[1]

The cause of most is not known.[1] The tumor may arise from connective tissue, fat tissue, skeletal muscle, blood or lymph vessels, and the peripheral nervous system.[2] Diagnosis is typically by medical imaging and biopsy.[1] Noncancerous soft tissue tumors are generally treated by surgical resection.[2] Cancerous ones typically require radiation therapy, chemotherapy, and more complex surgery.[2]

Most are noncancerous (benign), but a few may be cancerous (soft-tissue sarcoma).[3] An estimated 3,000 non-cancerous soft tissue tumor cases per 1 million population occur every year.[1] Around a third are lipomas, a third fibrohistiocytic and fibrous tumours, 10% vascular tumors, and 5% nerve sheath tumors.[1]
