Subcorneal pustular dermatosis is a chronic, benign disease characterized by sterile, pustular eruptions. They are typically localized in the flexor sides of the proximal extremities and the trunk.
The peak of manifestation is between the ages of 40 and 60 years, whereas men are much more affected than women (4: 1). These are superficial, flaccid pustules, which spread in garland or ring-shaped groups and develop into finely scaly areas with incrustation. Sometimes a slight hyperpigmentation occurs. The sessions come within a few hours and take a few days to recover. Patients sometimes complain of itching and discomfort.
