description: A low malignant potential soft tissue neoplasm of uncertain differentiation.  It typically affects young patients, presenting as a slowly growing nodular or cystic tumor mass, most often in the subcutaneous tissues of the extremities.  Occasionally, patients have systemic symptoms (anemia, fever, and weight loss).  This tumor has a relatively good prognosis.  A minority of patients develop local recurrences.  Metastases are rare.
