Benign soft tissue tumors in orthopedics

For the most part soft tissue tumors are benign. However, the clinical presentation, including radiological aspects, is not always clear. Therefore, a biopsy is necessary in some cases to detect malignant tumors at an early stage. The course of even benign tumors is sometimes complicated. A not insignificant group of local, aggressive or intermediary tumors tend to recur and in exceptional cases can be fatal. Benign soft tissue tumors are subdivided according to the current WHO classification from 2002. They are classified by the tissue they mimick. In clinical practice they are additionally grouped according to aggressiveness. Some benign soft tissue tumors occur in the context of a syndrome, leading to multiple tumors. In these cases there is the threat of a tumor becoming malignant (neurofibromatosis, Maffucci syndrome).
