DERM DIAGNOSES
MARC R. SALZBERG, MD, FACEP

The patient pictured presented with two hours of intense
pain and redness along the left side of her head and down
her left arm.
Though this could easily be mistaken for an infectious
process, it was actually reflex sympathetic dystrophy (RSD), also
referred to as complex regional pain syndrome (CRPS) type I.
By any name, however, this is a rare and poorly understood
neurological condition. It may manifest by way of sensory, focal
autonomic, or motor abnormalities. Pain is a common presenting
complaint; cutaneous vasomotor changes may also
be present, as was the case with this patient.
The patient was treated for the acute symptoms in the urgent
care setting with the standard of care for this syndrome
—diazepam, gabapentin (Neurontin), and acetaminophen/
oxycodone (Percocet)—and referred to a neurologist,
in whose care she underwent ganglion steroid injections. She
experienced slight resolution of symptoms and then remained
asymptomatic for three months.
She presented to urgent care again when the condition
flared, despite the fact that she was on medication. She is
still under the neurologist’s care and does not have a very
good prognosis, as this entity tends to get worse despite
treatment.
Typically, the prognosis for such patients is hard to predict;
however, in some patients the condition spreads to other areas
of the body.
