| Abstract: | The aim of this systematic review was to address the clinicopathologic inconsistencies noted with primary oral leiomyosarcoma in the literature by amassing the available data published into a comprehensive analysis. Eligibility criteria included publications of cases with dedicated immunohistochemical work‐up along with radiographs to evaluate location. Based on these criteria, the systematic review compiled 29 cases. Four primary location sites were identified in the reported cases: soft tissue presentation only, soft tissue with bony involvement, bony involvement only, and bony involvement with a soft tissue component. The majority of primary oral leiomyosarcoma cases reviewed showed a soft tissue predilection, which is in contrast to prior reports of jawbones being the most common site. In addition, there was an improved 5‐year survival rate for primary oral leiomyosarcoma limited to the oral cavity and gnathic bones without extension into paranasal sinuses. |
