RESUMO
BACKGROUND: Parathyroid incidentaloma is not a well-known entity. The aim of this study was to show its incidence and to discuss its management. METHODS: This was a prospective study analyzing cases of enlarged parathyroid glands discovered during thyroid surgery. The records of patients with parathyroid incidentaloma were reviewed. We also reviewed all cases of primary hyperparathyroidism (HPTPs) operated during the same period for comparison. RESULTS: Three cases of enlarged parathyroid were found. No clinical or biochemical features led us to suspect hyperparathyroidism before surgery, but a macroscopically enlarged parathyroid gland was discovered during the dissection and was removed in all three patients. CONCLUSIONS: Enlarged parathyroid glands discovered at the time of surgery may represent an early pathological stage responsible for overt primary hyperparathyroidism. In absence of major risk for recurrent nerve palsy, we recommend removal of any enlarged parathyroid discovered during neck surgery in order to avoid the risks of future surgical procedures, preserving in the same time at least one normal parathyroid gland.
