ABSTRACT
We report a case of epidermolysis bullosa simplex, with singular findings such as late appearance (sixth decade), and associated nephrotic syndrome and demyelinating polyneuropathy. A single patient (N-of-1) clinical trial established the usefulness of tetracycline therapy (500 mg/8 h) to diminish the number of new bullae. This report serves as an example of the use of single patient clinical trials in dermatology.
