Chest wall hamartoma of infancy

Chest wall hamartoma is a rare intrathoracic mesenchymal tumor occurring in infants and usually present from birth. The tumor arises from the ribs and is a histologically benign focal overgrowth of normal skeletal elements. Infants often present with respiratory problems. We report a case of a 5-month-old infant with a chest wall hamartoma who presented with a fever of unknown origin.
