Initial evaluations were inconclusive, and he was referred 3 weeks after symptom onset. Septic arthritis of the hip was suspected based on clinical and imaging findings, and arthroscopic irrigation was performed. However, symptoms persisted. Repeat magnetic resonance imaging revealed a rapidly enlarging tumor. Open resection was performed, and the lesion was diagnosed as a giant cell tumor of soft tissue.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>In children with acute hip pain, neoplastic disease should be considered.
