[Atypical clinical presentation of pigmented purpuric dermatosis].
The term pigmented purpuric dermatosis (PPD) is used for a group of mainly asymptomatic, sometimes pruritic dermatoses that are clinically characterized by an eruption of pinpoint purpuric lesions along with yellow, orange, red and/or brown, often patchy pigmented areas. Traditionally five subtypes have been distinguished, but atypical clinical patterns may also occur. Because of the variable clinical spectrum and the similar histopathologic findings, a strict nosological classification is sometimes difficult or even impossible to achieve. We report a case of PPD with atypical clinical features in a young woman, underlining the difficulties in the clinical classification of this spectrum of diseases.
