Rash of Fat Embolism

Q: Rash associated with Fat Embolism Syndrome (FES) usually occurs on the nondependent regions of the body? (select one)

A) True
B) False


Answer: A

The classic pathognomic red-brown petechial rash of FES occurs between  24 to 72 hours after long bone trauma. Characteristically, it occurs on the nondependent regions of the body i.e. head, neck, anterior thorax, axillae, and sub-conjunctiva. FES is a clinical diagnosis so the physical exam is of utmost importance. 1
