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
