Soft Tissue Sarcoma of the Head and Neck TNM Finding v8

**Semantic type:** Finding

**Definition:** A finding about one or more characteristics of soft tissue sarcoma of the head and neck, following the rules of the TNM AJCC v8 classification system. This classification system applies to soft tissue sarcomas of the head and neck except angiosarcoma, rhabdomyosarcoma of the embryonal and alveolar subtype, Kaposi sarcoma, and dermatofibrosarcoma protuberans, which do not share the same behavior and natural history. This is a new classification system that needs data collection before defining a stage grouping for head and neck sarcomas. Sarcomas of the orbit are staged according to the orbital sarcoma classification system. (from AJCC 8th Ed.)
