Although benign, its presentation can resemble aggressive bone lesions and may lead to diagnostic confusion, particularly when associated with pathological fractures.\n\nCase Report:: A 31-year-old male presented with right arm pain and deformity following trivial trauma. Imaging revealed an expansile osteolytic lesion in the humeral shaft with an associated fracture. Biochemical evaluation revealed marked hypercalcaemia and significantly elevated parathyroid hormone levels. Functional imaging localised a hyperfunctioning parathyroid lesion. Following metabolic correction, the patient underwent parathyroidectomy and intramedullary fixation of the humerus. Histological findings confirmed parathyroid adenoma and reactive osteoclastic bone changes consistent with Brown\u2019s tumour.\n\nConclusion: Metabolic bone disorders such as Brown\u2019s tumour should be considered when evaluating lytic lesions with fractures. Early biochemical evaluation is essential to avoid misdiagnosis and unnecessary aggressive surgical intervention.\n\nKeywords: Brown\u2019s tumour, hyperparathyroidism, pathological fracture, humerus, osteitis fibrosa cystica.<\/jats:p>","DOI":"10.13107\/jocr.2026.v16.i07.7614","type":"journal-article","created":{"date-parts":[[2026,7,9]],"date-time":"2026-07-09T08:35:16Z","timestamp":1783586116000},"page":"138-143","source":"Crossref","is-referenced-by-count":0,"title":["Brown\u2019s Tumor Presenting as a Pathological Humerus Fracture: A Rare Diagnostic Pitfall"],"prefix":"10.13107","volume":"16","author":[{"given":"L Adithya","family":"Narayan","sequence":"first","affiliation":[{"name":"Department of Orthopedic Surgery, Sri Ramachandra Institute of Higher Education and Research, Chennai, Tamil Nadu, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P.","family":"Velmurugan","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Sri Ramachandra Institute of Higher Education and Research, Chennai, Tamil Nadu, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.
