Managing these tumors requires careful, staged, multidisciplinary approaches. In Iran, despite advances, issues, such as delayed diagnosis, unplanned initial surgeries, and poor referral pathways, remain. This study aimed to present a clinical algorithm based on the current evidence and specifics of Iran&#39;s health system.</span></span></span></span></span></span><br> <span style="font-size:14px;"><span style="font-family:Tahoma;"><span style="line-height:2;"><span style="color:#0f4761"><span style="font-weight:normal"><b><span lang="EN">Methods:</span></b><span lang="EN"> We conducted a narrative review of authoritative scientific literature, international guidelines (National Comprehensive Cancer Network, European Society for Medical Oncology), and local epidemiologic studies in Iran. The focus was on integrating clinical, radiologic, and pathologic findings to achieve accurate diagnosis and to formulate appropriate treatment plans.</span></span></span></span></span></span><br> <span style="font-size:14px;"><span style="font-family:Tahoma;"><span style="line-height:2;"><span style="color:#0f4761"><span style="font-weight:normal"><b><span lang="EN">Results:</span></b><span lang="EN"> Accurate differential diagnosis relies on identifying specific radiologic patterns and avoiding unnecessary biopsies of lesions exhibiting pathognomonic benign features, commonly referred to as &quot;leave-me-alone lesions.&quot; Osteosarcoma is the most prevalent malignant bone tumor in Iran and exhibits a bimodal age distribution. Biopsy should be the final step in diagnosis, ideally performed by the surgeon responsible for definitive treatment. Uninformed interventions on soft tissue masses without appropriate imaging may contaminate tissue planes and reduce the likelihood of limb-salvage surgery.</span></span></span></span></span></span><br> <span style="font-size:14px;"><span style="font-family:Tahoma;"><span style="line-height:2;"><b><span lang="EN">Conclusion:</span></b><span lang="EN"> Establishing multidisciplinary teams at referral centers, educating general practitioners on red flag signs, and reforming the patient referral pathway are pivotal strategies for improving patient outcomes in Iran.</span></span></span></span></h3> Primary musculoskeletal tumors, Bone tumors, Soft tissue tumors, Osteosarcoma, Differential diagnosis, Leave-me-alone lesions, Biopsy strategy 0 0 http://jros.iums.ac.ir/browse.php?a_code=A-10-1054-1&slc_lang=en&sid=1 Mohammadreza Dolikhani Mohammadreza.dolikhani.78@gmail.com 10031947532846008677 10031947532846008677 No Bone and Joint Reconstruction Research Center School of Medicine Iran University of Medical Sciences Shafa Yahyaeian Hospital Tehran, Iran khalil kargar shooroki khalilkargar63@gmail.com 10031947532846008678 10031947532846008678 Yes Bone and Joint Reconstruction Research Center School of Medicine Iran University of Medical Sciences Shafa Yahyaeian Hospital Tehran, Iran Babak Toloue Ghamari babak.toloueghamari@gmail.com 10031947532846008679 10031947532846008679 No Department of Orthopedic Surgery, Clinical Research Development Unit of Shohadae Tajrish Hospital, Shahid Beheshti University of Medical Sciences, Tehran, Iran Behnam Sour sourbehnam1374@gmail.com 10031947532846008680 10031947532846008680 No Bone and Joint Reconstruction Research Center School of Medicine Iran University of Medical Sciences Shafa Yahyaeian Hospital Tehran, Iran Ghazaleh Shakibamaram ghshakiba2000@gmail.com 10031947532846008681 10031947532846008681 No Bone and Joint Reconstruction Research Center School of Medicine Iran University of Medical Sciences Shafa Yahyaeian Hospital Tehran, Iran
