Frontal bossing is an unusually prominent forehead, sometimes associated with a heavier than normal brow ridge.
Frontal bossing is seen only in a few rare syndromes, including acromegaly, a chronic disorder caused by too much growth hormone, which leads to enlargement of the bones of the face, jaw, hands, feet, and skull.
