Introduction:

Brown tumors caused by hyperparathyroidism, primary or secondary, are lesions of the vascular soft intraosseous tissue that more frequently develop in long bones; occasionally, the lesions tend to be peripheral located on the alveolar ridges of the maxilla and mandible.

Objective:

To describe a case of a patient under hemodialysis treatment with brown tumors of the maxillofacial region due to secondary hyperparathyroidism.

Clinical case:

We describe a 39-year-old male, he received hemodialysis for 20 years, for chronic renal failure with secondary hyperparathyroidism, and he comes by facial deformity in the image evaluation, there are osteolytic lesions in maxilla and mandible were suspected to be brown tumors.

Conclusions:

This manifestation of secondary hyperparathyroidism can be expected to occur with increased longevity of patients with renal failure. A complete evaluation can help to reach a correct diagnosis.
