PY - 2018 T2 - Rudolph's Pediatrics, 23e AB - The World Health Organization divides soft tissue tumors into 4 categories based on clinical behavior: benign, intermediate (locally aggressive), intermediate (rarely metastasizing), and malignant. Benign soft tissue tumors such as lipoma, nodular fasciitis, and hemangioma predominate in pediatric patients. Certain intermediate-behavior soft tissue tumors, including desmoid-type fibromatosis and dermatofibrosarcoma protuberans, occur frequently in childhood. The more than 30 histologic subtypes of malignant soft tissue tumors comprise approximately 7% of all cancers among children and adolescents. In children, rhabdomyosarcoma (RMS) is by far the most common soft tissue sarcoma, accounting for about 40% of cases. Because RMS predominates, the remaining malignant soft tissue tumors are often referred to as non-rhabdomyosarcoma soft tissue sarcoma (NRSTS).
