Pigmented Purpuric Dermatoses
The aetiology is unknown but important contributory factors include venous hypertension, exercise and gravitational dependency [2] . Histology shows a perivascular lymphocytic infiltrate of T cells centred on the superficial small blood vessels of the skin, suggesting that cell-mediated immunity plays a part [3] . There is swelling of endothelial cells and narrowing of the lumen. Extravasation ...

متن کاملPigmented purpuric dermatoses.
Pigmented purpuric dermatoses (PPD) are a group of histopathologically similar conditions that are primarily differentiated based on morphology. The basic pathological finding is a lymphocytic perivascular infiltrate with hemorrhage limited to the papillary dermis without fibrinoid necrosis of the vessels. The etiology is unknown; they run a chronic course and are fairly resistant to treatment....
