Primary hyperparathyroidism is a common endocrinology anomaly which involves head and neck region. The diagnosis and treatment of parathyroid adenoma however still remains a challenge. Giant parathyroid adenomas are rare and involve more surgical expertise. Retrospective study was carried in Departments of ENT and Endocrinology, SMS Medical College and Hospital, Jaipur. Records of patients operated between 2010 and 2019 were evaluated and analysed for size and site of parathyroid adenomas, biochemical parameters, intra-operative findings and postoperative course. Tumours with size > 3 cm were termed as giant parathyroid adenomas and this is a rarity in literature. Records of 79 patients were found to be complete. Out of these 9 had giant parathyroid adenomas: 4 left inferior, 2 right inferior, 1 ectopic location (superior mediastinum) and 1 each in left and right superior glands. The size, symptomatology and biochemical parameters are discussed in light of available literature. Giant parathyroid adenomas are a rare entity and their behaviour are same as of non giant parathyroid adenomas. In the view of literature published on pub Med, this is found to be largest case series on parathyroid Adenoma considering size more than 3 cm.
