Frontal bossing

Table of Contents

Definition

Frontal bossing is an unusually prominent forehead, sometimes associated with a heavier than normal brow ridge.


Considerations

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.


Common Causes
  • Acromegaly
  • Basal cell nevus syndrome
  • Congenital syphilis
  • Cleidocranial dysostosis
  • Crouzon syndrome
  • Hurler syndrome
  • Pfeiffer syndrome
  • Rubinstein-Taybi syndrome
  • Russell-Silver syndrome (Russell-Silver dwarf)
  • Use of the antiseizure drug trimethadione during pregnancy
