What are the clinical features of EED?

How is EED diagnosed?

Several tests are available to establish a diagnosis of EED.

What is the treatment for EED?

EED is a chronic and progressive skin disease that may last as long as 25 years. However, in some cases after evolving over a 5-10 year period it may spontaneously clear.

Medication can be used to limit progression of the disease.

Dapsone is considered the drug of choice for EED, mainly because of its rapid onset of action and clinical experience has shown good responses. However, lesions promptly recur following withdrawal of the drug.

Other drugs that have been occasionally reported to be effective include:

Oral corticosteroids are generally ineffective.
