title: [Brown tumor of the maxillary sinus: a case report].
abstract: Brown tumor of the paranasal sinuses is rare. It is a benign fibro-osseous lesion, typically presenting as an expansile mass that leads to a cortical defect. We presented the radiological findings of a brown tumor of the right maxillary sinus in a 13-year-old boy who presented with complaints of swelling in the right maxillary region, headache, and epistaxis. Biochemical findings were compatible with primary hyperparathyroidism. The lesion was removed by partial parathyroidectomy. No recurrences or residual mass were detected during a six-month follow-up period.
