Huge undifferentiated fibroblastic sarcoma of the foot and lower leg: impact of diagnostic delay and discussion of an entity.

We report a case of a 40-year-old female patient with a huge fibroblastic differentiated sarcoma of the left foot. After sampling all clinical, pathological and imaging information, the case was presented to the interdisciplinary tumour conference. Further treatment and medical care took place in the department of orthopaedics and orthopaedic surgery of our university hospital. Treatment consisted of amputation of the left foot and lower leg as an extremity-preserving surgical procedure was not possible because clear surgical margins could not be achieved with preservation of a functional rest of ankle and foot. Till date, no metastases have occurred.
