Abstract

Introduction: It is not uncommon for a patient with a brown tumor to be misdiagnosed as a primary bone tumor, while the contrary is not true. The association of bone sarcomas with hyperparathyroidism is quite rare, and here, we report one such case where Ewing's sarcoma was misdiagnosed as a brown tumor. Care description: A 17-year-old lady was treated elsewhere for a pathological fracture of the left femur with open reduction and internal fixation (ORIF) with intramedullary (IM) nailing. On evaluation, the patient was found to have hyperparathyroidism secondary to parathyroid adenoma. Following 1 month of parathyroid gland excision (histologically proven to be adenoma), patient developed increased swelling at the ORIF site which on further evaluation was found to be Ewing's sarcoma. Despite the aggressive local and systemic therapy, patient progressed to develop distant metastasis. Conclusion: Ewing's sarcoma can mimic brown tumors, and a high degree of suspicion is required to make a proper diagnosis. These patients are better treated at high-volume centers to avoid misdiagnosis and mismanagement.
