Non-cutaneous soft tissue tumors and pseudotumors in the foot and ankle reported in Brazilian services

Objectives: Review the histological types of non-cutaneous soft tissue tumors and pseudotumors that affect the foot and ankle,reported in Brazilian health services.Methods: An integrative review of the literature from the Scielo and PubMed platforms, based on the descriptors “Soft Tissue Tumors,”“Pseudotumors,” “Foot, “Ankle,” and “Brazil.” Those who answered the following research question: “What are the non-cutaneous softtissue tumors and pseudotumors in the foot and ankle reported in Brazilian health services?” were included. The combination of eachauthor’s analysis contributed to reducing possible biases.Results: Six articles were selected, yielding 23 reports of tumors and pseudotumors, which were subsequently categorized intomalignant and benign tumors. There were five benign findings: three benign tumors, two giant cell tumors, one fibromatosis, andtwo pseudotumors classified as synovial chondromatosis. Eighteen malignant findings were reported: seven unspecified soft tissuesarcomas, four synovial sarcomas, three myxofibrosarcomas, one fibrosarcoma, one liposarcoma, one undifferentiated pleomorphicsarcoma and one papillary intralymphatic angioendothelioma.Conclusion: In the last ten years, more reports of malignant than benign tumors have been reported. However, this finding does notnecessarily reflect the Brazilian epidemiological reality, as it may represent a view in which resected benign tumors and pseudotumorsare often not sent for anatomopathological study or reported in the literature.
