[Amicrobial pustulosis of the folds: report of a new case and review of literature]. / Pustulosis amicrobiana de las flexuras. Descripción de un nuevo caso y revisión de la literatura.

Amicrobial pustulosis of the folds is a rare disorder characterized by a recurrent sterile pustular rash mainly affecting the skinfolds, scalp, and periorificial regions such as around the external auditory meatus. Few cases have been reported in the literature, most of them occurring women and all of them associated with some immunological disorder, the most common being lupus erythematosus. We present a new case of amicrobial pustulosis of the folds in a woman; the only immunologic abnormality detected was an elevation of immunoglobulin E. We have also reviewed the 35 cases reported in the literature.
