Abstract

Oral metastatic sarcomas (OMSs) occur only occasionally, and information about their characteristics is based on the restricted number of cases reported in the literature. This study aims to systematically review the English literature to recognize the clinicopathologic characteristics of OMSs. An electronic search was performed in PubMed Central and Scopus databases. The search included all the published articles (human case reports and case series) up till April 2023, with no time restrictions. OMSs were slightly more prevalent in males in their fifth to seventh decades of life. However, a high percentage of OMSs has been reported in the second decade of life. Lower extremities, breasts and uterus are the most common primary origin of metastatic sarcoma. Gingiva and mandible were common locations in the oral cavity for metastatic deposits. Generally, they demonstrated widespread affliction. The mean time interval between primary tumor detection and diagnosis of the oral metastasis was about 33.54 ± 36.19 months. Death was reported in 83 patients (67.48 %) with a mean survival rate of 7.98 ± 10.30 months. The most common microscopic tumor types were leiomyosarcoma (n = 21, 17 %), followed by angiosarcoma (n = 20, 16.26 %) and osteosarcoma (n = 18, 14.63 %). In conclusion, while oral metastases of sarcomas are not common, those should be considered in the differential diagnosis of the oral lesions. Although OMSs show a high occurrence in the 7th decade of the life, the average age of patients with oral involvement is lower than the overall metastatic lesions. OMSs may present as widespread disease with poor prognosis. © 2023 Elsevier Masson SAS
