Soft tissue masses that arise on the back, abdominal wall or extremities can easily be excised (removed) in the office operating room or as outpatient surgery. The most common masses are fatty tumors (lipomas) or hair follicle cysts (sebaceous cysts). These masses are benign tumors, but cancerous tumors must also be ruled out and that it is why a biopsy is essential. Most common cancerous masses are sarcomas that can arise from muscle, fat, joint, nerves or blood vessels. Cancers that arise from lymph nodes (lymphomas) must also be ruled out with biopsy. Please make your reservation to see Dr. Tomas to have these masses evaluated.
