A Case of Subcorneal Pustular Dermatosis with Atypical Distribution / 대한피부과학회지

ABSTRACT

Subcorneal pustular dermatosis(SPD) or Sneddon-Wilkinson disease is a chronic, relapsing, pustular eruption generally involving the intertriginous area and affecting mainly elderly women. We report a case of SPD presenting in a 24-year-old female with erythematous circinate annular peripheral scaly patches on her right thigh. Histopathologically, the subcorneal pustules contained numerous neutrophils, with only a few eosinophils. Underlying stratum malpighii was slightly edematous and contained small numbers of neutrophils. No acantholytic cells or spongiosis were found. The patient was treated by dapsone successfully.
