RESUMO
BACKGROUND AND OBJECTIVES: Parathyroid gland tumor is a relatively rare disease in Korea. The purpose of our study is to assess the clinical features, diagnostic tools and therapeutic results. MATERIALS AND METHOD: Seven patients with parathyroid gland tumor were analyzed retrospectively. They were diagnosed and received surgical therapy in our hospital from 1995 to 1999. The patients were all female with mean age of 45.3 years (in the range of 21-64 years old). We used ultrasonography, computed tomography, magnetic resonance imaging, parathyroid scan and 18F-FDG positron emission tomograph (PET) to identify the location of parathyroid gland neoplasm. RESULTS: All patients received proper surgical management. Three patients were diagnosed as parathyroid carcinoma, three as parathyroid adenoma and one patient as cavernous hemangioma. Two patients were found as recurrent tumor, Parathyroid carcinoma recurred in one patient, and parathyroid hyperplasia occurred in patient who was previously diagnosed as parathyroid adenoma. CONCLUSION: The results would he a useful guideline for better diagnostic strategies, proper surgical management and follow-up study for recurrence in the parathyroid gland tumor.
