Introduction
Hereditary multiple exostoses (HME) is an autosomal dominant disease characterized by abnormal growth of bones, mainly involving epiphyses of long bones. In HME involvement of Sternum is very rare1. Large sternal mass compressing airway needs to be managed by a multidisciplinary approach to prevent injury to great vessels, heart, and risk of fatal respiratory failure during induction of anesthesia. We are reporting this case due to a very rare presentation of a large sternal exostoses compressing airways, which was managed successfully.
