Pigmented progressive purpuric dermatosishttps://en.wikipedia.org/wiki/Pigmented_purpuric_dermatosis
Pigmented progressive purpuric dermatosis refers to the non-itching skin conditions characterized by purpuric skin eruptions. The size of the lesion is from 0.3 to 1 cm and are most often seen in the lower extremities. The cortisone cream will help for the itching and improving the discoloration of the skin. Pigmented progressive purpuric dermatosis causes no other symptoms beside skin discoloration. The lesions are most frequent on the lower limbs, but may occur anywhere on the body, including the hands, arms, torso and even the neck.

    Pigmented purpuric dermatoses (PPD) include several skin diseases characterized by multiple petechial hemorrhage as consequence of capillaritis. PPD generally present with red to purple macules that progressively evolve to golden-brown color as the hemosiderin is reabsorbed.
     Schamberg Disease 32809367 
    Schamberg disease represents the most common type of pigmented purpuric dermatoses (PPDs), a chronic, benign, cutaneous eruptions characterized by petechiae, purpura, and increased skin pigmentation (brown, red, or yellow patchy). The PPDs are grouped into five clinical entities: Schamberg's purpura, Majocchi purpura, lichen aureus, Gougerot-Blum purpura and, eczematoid-like purpura of Doucas and Kapetanakis. Schamber disease (SD) has also been called: progressive pigmentary dermatosis of Schamberg, purpura pigmentosa progressive and, Schamberg's purpura. It is commonly seen in males and mainly affects the tibial regions, and could involve thighs, buttocks, trunk, or upper extremities.

    Information on 113 patients with PPD was analyzed, and 38 subjects with skin biopsy were included for this study. Schamberg's disease was the most frequent clinical type (60.5%). Concomitant diseases included hypertension (15.8%), diabetes (10.5%), and others. Associated medication histories included statins (13.2%), beta blockers (10.5%), and others. Possibly associated etiologic factors were recent upper respiratory infection (5.3%), high orthostatic pressure due to prolonged standing (2.6%), and strenuous exercise (2.6%). A total of 36 patients (94.7%) were treated with one or more treatment methods, including oral antihistamines, pentoxifylline, topical steroids, and/or phototherapy.
