Abstract Introduction Brown tumors are a rare focal manifestation of osteitis fibrosa cystica which results from hyperparathyroidism. Chronic kidney failure may lead to secondary or tertiary hyperparathyroidism and thus to osteitis fibrosa cystica and brown tumors. Case presentation A 60-year-old man with a history of diabetes mellitus and chronic kidney failure presented with a 15-day history of dyspnea cough malaise and fever. Initially there was little correlation between his history and his physical examination. Various pulmonary cardiac and infectious etiologies were ruled out. A chest X-ray showed a costal mass that was further verified by tomography and gammagraphy. The mass was suspected of being neoplastic. After a failed biopsy the mass was removed surgically and on histopathology was compatible with a giant-cell tumor versus a brown tumor caused by hyperparathyroidism. Laboratory tests showed elevated calcium phosphate and parathyroid hormone .
