Gynaecomastia is a well-recognized manifestation of thyrotoxicosis occurring in a widely variable percentage. Some studies have reported the percentage to be high as 40% while others report it being around 10%. The variation can be attributed to the difference in the criteria used to define gynae-comaslia or racial factors. However, thyrotoxicosis presenting with gynaceomastia as an intial manifestation is very rare. Only handful case reports are found in literature. Here we present a case of 35-year-old Indian male, with thyrotoxcosis who presented initially with painful bilateral gynaceomastia.
