RESUMEN

CASE: A 17-year-old boy presented to the clinic complaining of right hip pain after soccer participation. Clinical findings and imaging studies led to the diagnoses of femoroacetabular impingement and diffuse tenosynovial giant cell tumor (TGCT). Comprehensive arthroscopic management and biopsy revealed a diagnosis of osteosarcoma. The patient subsequently underwent chemotherapy, surgical resection, and reconstruction. CONCLUSION: Osteosarcoma of the proximal femur may mimic TGCT on imaging studies because osteosarcoma may show changes suggestive of inflammation. We recommend heightened clinical awareness and a comprehensive differential workup in the management of presumed TGCT about the hip in the pediatric patient population.

RESUMEN

CASE: Our patient is a 34-year-old male aHthlete who presented for consultation after left knee discomfort and pressure for greater than 2 years. Advanced imaging revealed a nonspecific intraarticular suprapatellar lesion with subsequent ultrasound-guided core biopsy demonstrating a spindle cell proliferation consistent with superficial fibromatosis. Thus, the patient underwent an open en bloc surgical resection by a fellowship-trained orthopaedic oncologist. CONCLUSION: As the first reported case of intraarticular fibromatosis of the knee, this case highlights the importance of a thoughtful approach to the management of nonspecific intraarticular lesions through a comprehensive and collaborative strategy to decrease patient morbidity and optimize outcomes.
