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 ...

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....

Pigmented purpuric dermatoses are chronic and relapsing disorders characterized by a symmetrical rash of petechial and pigmentary macules, mainly confined to the lower limbs. Purpura annularis telangiectodes of Majocchi is a less common variant of Pigmented purpuric dermatoses characterized by punctate telangiectatic macules progressing to annular, hyperpigmented patches with central clearing a...

Background and aim: Pigmented purpuric dermatoses are a group of chronic and recurrent skin diseases resulting from lymphocyte-mediated leakage of erythrocytes. No effective treatment has been suggested for these conditions. This study was performed to evaluate the efficacy of oral pentoxiphylline in the treatment of pigmented purpuric dermatoses.Materials and Methods: ...

We report the case of a 12-year-old girl who presented a rash with reddish-brown patches on the trunk and extremities indicative of pigmented purpuric lichenoid dermatitis of Gougerot-Blum (PPLD). The histological findings were characteristic for PPLD, thus supporting the diagnosis. Topically administered corticosteroid led to a fast resolution of all symptoms. PPLD is not seen commonly in youn...

Purpuric pigmented dermatoses represent a form of chronic, recurrent capillaritis characterized by petechiae and purpuric macules over the lower limbs. We report three female cases who presented with clinical features of purpuric pigmented dermatosis with unusual histopathologic features. The first patient had golden-brown pigmented purpura over bilateral knees, shins and dorsal feet. The secon...
