[en] The subcorneal pustular dermatosis of Sneddon and Wilkinson belongs to the heterogeneous group of neutrophilic dermatosis. This unique disorder is characterized by a superficial pustular eruption. The pustules are flaccid and aseptic. They develop predominantly on the trunk and in the groins, axillae and submammary areas. This disease is benign and chronic. However, it can be associated with some other conditions such as lymphoproliferative and myeloproliferative diseases. Dapsone is the treatment of choice to control the skin manifestations.
