Breast hamartoma with intrathoracic extension in a 13-year-old boy

Breast hamartoma is a rare tumor that has been reported only thrice in a male breast. The pediatric age group is seldom involved. We present a case of breast hamartoma in a 13-year-old boy, which interestingly, extended through but without definite involvement of the chest wall into the thoracic cavity. In view of occasional recurrence and documented malignancy in hamartomas, tumor was excised along with two ribs.
