A case of recurrent erythema multiforme and its therapeutic complications.
BACKGROUND
We report a patient with recurrent erythema multiforme (recurrent EM) who developed iatrogenic Cushing's syndrome due to prolonged corticosteroid use.


METHODS
The patient had been treated with multiple courses of oral and intramuscular prednisolone over a 10-year period to suppress his recurrent and episodic symptoms. This resulted in the development of iatrogenic Cushing's syndrome with secondary adrenal suppression and steroid-induced osteoporosis.


METHODS
The patient was treated with continuous acyclovir therapy in addition to azathioprine. This combination controlled his disease and enabled us to stop his requirement for high-dose prednisolone.


RESULTS
The patient responded well to this treatment regimen and has been in remission to date.


CONCLUSIONS
This represents a severe case of recurrent EM and the side effects associated with years of chronic high-dose steroid usage. We discuss the therapeutic options to aid physicians in treating this disabling condition.
