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]
