Blunt trauma in soccer. The initial manifestation of synovial sarcoma

: Report on a young man, who was operated upon after adequate trauma following the diagnosis "organizing haematoma of the adductorial compartment". Surprisingly we found intraoperatively tumor suggilations. According to the definition of Enneking the surgical procedure was finished as "marginal excision" and the patient was referred to an oncological center. After multimodal therapy the patient is meanwhile tumor and recurrence free for 5 years. In case of such an unexpected diagnosis the importance of paying attention to the criterias of an "incisional biopsy" is emphasized. The concept of a "conceived biopsy" is explained in preoperatively malignant looking tumors. The outstanding responsibility of the surgeon for prognosis (local recurrence) and patients quality of life (amputation versus limb salvaging) is elaborated.
