Otolaryngologists are often requested to operate in the case of primary hyperparathyroidism which is almost always derived from a parathyroid adenoma and parathyroid hyperplasia. The diameter of such lesions is usually about 10 mm, based on the literature. We report herein on a surgical procedure we performed for a giant parathyroid adenoma. A 67-year-old man with bilateral lower limb pain, weakness and dysbasia was referred to Fujinomiya City General Hospital from a clinic in the city. Physicians diagnosed him as having primary hyperparathyroidism and a parathyroid tumor with various examinations, and requested us to extirpate the tumor. We performed a left inferior parathyroidectomy. The tumor measured 75×50 mm, weighed 70 g and was pathologically diagnosed as adenoma. Based on the data from various Japanese references, the tumor was considered as a giant parathyroid adenoma in Japan.
