[Recommendations for anatamo-pathologic management of soft tissue sarcomas in the adult. Pathologists of the FNCLCC Sarcoma Group (Fédération Nationale des Centres de Lutte Contre le Cancer)].

Adult soft tissue sarcomas comprise a heterogeneous group of rare tumors having a wide range of clinical, gross and histological presentations. Outcome is variable. The pathologist's task is difficult but must be based on a rigorous method. The aim of these recommendations is to describe the main steps of management: collection of clinical information, performing biopsy, handling the fresh specimen, gross examination, histological examination, use of special techniques, definition of the main prognostic factors and key features of the pathology report.
