frontal bossing

Last reviewed 01/2018

Frontal bossing is usually a consequence of erythropoeisis occuring away from long bones; it is thus a finding in conditions of chronic anaemia such as:

  • thalassaemia major
  • sickle cell anaemia

In addition it may be noted as a dysmorphic feature in:

  • Russell-Silver dwarfism
  • Hurler's syndrome
