Spontaneous extracapsular parathyroid adenoma hemorrhage: when surgery is required?

Spontaneous bleeding is a rare but serious complication of parathyroid adenomas and few cases were reported in the literature. Clinical manifestations and treatment may vary but sometimes an immediate surgery is required. In other cases a conservative approach can be preferred based on clinical stability and patients' conditions. The purpose of this work is to describe our case and to carry out a review of the current literature on this topic.
