Palliative Free Flap Surgery for Plantar Sarcoma: A Case Report and Literature Review.

We report a case of palliative surgery in a 73-year-old patient with metastatic plantar sarcoma. The patient underwent resection and irradiation of an undifferentiated spindle cell sarcoma in the right plantar region. The wound was not closed and systemic metastases were observed. The chief complaint of the patient on his first visit to our department was difficulty walking due to pain in the right plantar region. Since we were unsuccessful in relieving the pain with conservative treatment, we decided to perform a palliative free tissue transfer to the right plantar. The surgery was successful, the skin ulcer healed, and the pain was relieved after the surgery. When performing palliative surgery, more detailed preoperative management and planning are necessary to achieve a successful outcome. The selection of the flaps according to the local lesion and metastatic lesions and changes in the local hemodynamics should be considered when planning.
