INTRODUCTION: Brown tumors are rare focal giant-cell lesions that arise as a direct result of the effect of parathyroid hormone on bone tissue in some patients with hyperparathyroidism. Brown tumors can affect the mandible, maxilla, clavicle, ribs, and pelvic bones. Therefore, diagnosis requires a systemic investigation for lesion differentiation. CASE PRESENTATION: We present a 42-year-old Greek woman, with a rare case of brown tumor of the maxillary sinus due to primary hyperparathyroidism. Primary hyperparathyroidism is caused by a solitary adenoma in 80% of cases and by glandular hyperplasia in 20%. CONCLUSIONS: Differential diagnosis is important for the right treatment choice. It should exclude other giant cell lesions that affect the maxillae.
