dermatofibrosarcoma protuberans  listen  (DER-muh-toh-FY-broh-sar-KOH-muh proh-TOO-beh-ranz)

  A type of tumor that begins as a hard nodule and grows slowly. These tumors are usually found in the dermis (the inner layer of the two main layers of tissue that make up the skin) of the limbs or trunk of the body. They can grow into surrounding tissue but do not spread to other parts of the body. These tumors are related to giant cell fibroblastomas.
