Özet
Background: The brown tumor is one of the pathognomonic findings of primary hyperparathyroidism and is a focal, tumor-like bone lesion caused by the osteoclastic transformation of bone. Case presentation: We present a case of a brown tumor located in the left maxilla of a 44-year-old male patient. The detected brown tumor was the first clinical manifestation of primary hyperparathyroidism. In this way, the underlying long-term primary hyperparathyroidism caused by a large parathyroid adenoma was finally diagnosed. Conclusions: Primary hyperparathyroidism can be recognized by the presence of an osteolytic lesion called a brown tumor. It should be kept in mind that the first clinical manifestation of primary hyperparathyroidism, accompanied by increased parathyroid hormone and hypercalcemia, may be a brown tumor.
