Chronic vulvar purpura

We described a 56-year-old Japanese woman with a long-standing asymptomatic vulvar purpuric lesion. Histological studies revealed massive hemorrhage, deposition of hemosiderin and a moderate lymphohistiocytic infiltration. We speculate that chronic intrapelvic congestion with increased venous pressure possibly due to abdominal ptosis played an important role in the pathomechanism for this persistent purpuric lesion of the vulva.
