They are caused by increased osteoclastic activity leading to an abnormal bone metabolism.Case Description: Here, we present the case of a 58-year-old male, who presented with painful bony lesions, initially attributed to metastatic disease. After biochemical workout, imaging and biopsy, the nature of the lesions was revealed. We discuss the differential diagnosis and clinical management of the disease.Conclusion: Patients with brown tumors should be assessed in the differential diagnosis of bony lesions and should always be tested for hyperparathyroidism. An early diagnosis is crucial for the successful treatment of such patients.Keywords: brown tumor, hyperparathyroidism, chronic kidney disease, case report
