Abstract
- Progressive pigmented purpura(Schamberg type) is of uncertain etiology. The lesion is characterized by a symmetrical rash of petechial and brown pigmented macules limited to the legs. Unilateral occurrence is considered a rarity. We report a 37-year-old woman presented with a 20-year history of unilateral distribution of purpuric and pigmented lesions scattered on the right shin and calf. Histopathologic feature showed band-like infilterate of superficial perivascular lymphohistiocytes with extravasation of erythrocytes and hemosiderin deposition in the upper dermis.
