Pigmented purpuric dermatoses (PPD) dia vondron'ny toetry ny hoditra voamariky ny faritra kely misy rà eo ambanin'ny hoditra noho ny fivontosana kapila. Matetika ny PPD dia manomboka amin'ny loko mena ka hatramin'ny volomparasy izay lasa mivolombolamena-volontsôkôlà rehefa miverina ny hemosiderine.
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 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.

Ny fampahalalana momba ny marary 113 miaraka amin'ny PPD dia nodinihina, anisan'izany ny 38 izay nanao biopsy hoditra ho an'ity fianarana ity. Ny karazana klinika mahazatra indrindra dia ny aretin'i Schamberg (60,5%) . Ny fepetra hafa miaraka amin'ny PPD dia ny fiakaran'ny tosidrà (15. 8%) , ny diabeta (10. 5%) , ary ny hafa. Ny tantaran'ny fitsaboana dia nanambara statins (13. 2%) , beta blockers (10. 5%) , ary ny hafa. Ny anton-javatra mety mifandray amin'ny PPD dia nahitana aretin'ny taovam-pisefoana ambony vao haingana (5. 3%) , fijanonana maharitra mitarika ho amin'ny fanerena orthostatika ambony (2. 6%) , ary fanatanjahan-tena mafy (2. 6%) . Ny fitsaboana dia natao tamin'ny marary 36 (94. 7%) - oral antihistamines, pentoxifylline, topical steroids, and/or phototherapy.
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.
