Abstract
INTRODUCTION: In adults, fibrosarcoma (FS) of the bone is a rare occurrence. Infantile FS, particularly in the distal radius, is an exceedingly uncommon tumor and, to the best of our knowledge, has not yet been documented in the literature. In the subsequent report, we present a case involving a 2-year-old male diagnosed with primary FS of the distal radius. CASE REPORT: We hereby report the case of a 2-year-old Caucasian boy presenting with primary bone FS in the distal radius. X-rays revealed an osseous mass with an extraosseous component. MRI showed heterogeneous enhancement, suggestive of non-liquefied necrosis or possible fibrosis within the extraosseous soft-tissue component. The patient underwent a resection of the tumor, followed by central translocation of the ulna. CONCLUSION: Managing infantile FS of the bone requires a multidisciplinary approach. A high index of suspicion is crucial for diagnosing the tumor. Further studies are needed to enhance our approach and management of infantile FS of the bone.
