Pigmented purpuric dermatosis after taking a dietary supplement.

Pigmented purpuric dermatoses (PPDs) are a group of histologically similar skin eruptions characterized by a perivascular lymphocytic infiltrate with extravasated erythrocytes. The etiologies of these conditions are unknown, but triggering factors such as systemic diseases, infections, drugs, and foods have been described. Here, we present a patient who developed pigmented purpura 30 days after initiating a dietary supplement that contained selenium, natural vitamin E, and a parsley concentrate, specifically, Parselenium E. One month after stopping the dietary supplement, the lesions disappeared and no new lesions have developed.
