Familial Gynecomastia of Unknown Etiology: A Case Report

Gynecomastia is a benign enlargement of the male breast (usually bilateral but sometimes unilateral) resulting from a proliferation of the glandular component of the breast. It is a common clinical condition. We have reported here a case of 16 years old male who presented with bilateral gynecomastia. In his family history his Grandfather, Father and cousin brother suffered from same disease. As all the relevant investigations came out to be normal, it was considered as idiopathic condition and was diagnosed as familial gynecomastia.
