Outcome of Soft Tissue Popliteal Sarcomas: 15 Years of Experience.

Background: Soft-tissue sarcoma involving the popliteal fossa remains challenging because it is difficult to achieve wide margins with limb salvage in this location. Adjuvant therapy is frequently necessary, and limb function can be adversely affected. We reviewed our experience with these tumors. A variety of lesions can be identified within the posterior knee, ranging from simple Baker's cysts to malignant lesions. We present a review of frequently encountered and less common entities using an anatomic sieve, with the aim of providing a diagnostic approach to popliteal fossa masses Soft-tissue sarcomas (STSs) arising from the popliteal fossa present a challenge with regard to local control of primary tumors. Method: In the study, patients who were operated for a mass in the popliteal region between 2007 and 2018 in our clinic were retrospectively analyzed. Patients were categorized by parameters such as age, gender, extremity direction, type of surgery, AJCC scores, surgical margin, tumor size, presence of distant metastases, mass pathology, follow-up time and MSTS score. Results: Our study included 13 patients (eight women and five men). The mean age was 48 (range 12-84) years. The mass was located in the left knee in nine patients and the right knee in four patients. Frequent histologic diagnoses were for maliğn soft-tissue tumor liposarcoma ( Conclusion: The popliteal region is a rare area in terms of mass localizations. Inpatients presenting with knee pain, regardless of external findings such as swelling ornot, tumors located in the popliteal region should be considered in patients withoutpathology on direct radiography.
