Clear cell papulosis (pagetoid papulosis) in a non-Asian patient.

Clear cell papulosis is a recently described disorder which is characterized by multiple flat, slightly elevated, hypopigmented papules, distributed mainly on the lower part of the trunk of healthy children. Histologically, the disease shows 'clear cells' with a pagetoid appearance spread among keratinocytes in basal and suprabasal layers of the epidermis. These cells stain for AE1, CEA and EMA, making a relationship to eccrine or apocrine elements likely. All cases reported until now describe Asian children. The first European child with clear cell papulosis is presented. Copyright 2001 S. Karger AG, Basel
