Pigmented purpuric dermatoses (PPD) kapilaren hantura ondorioz azalaren azpian odol-azaleko eremu txikiek markatutako larruazaleko gaixotasunen multzoa da. PPD normalean orban gorri eta more gisa hasten dira; gero, urre-marroi bihurtzen direnak, hemosiderina berriro xurgatzen denean.
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 pigmented purpuric dermatoses (PPDs) motaren ohikoena da, orban gorri edo more txikiak eta larruazaleko kolorearen areagotzea (marroi, gorri edo horizko adabakiak) ezaugarri diren azaleko gaixotasun kronikoak. PPDak bost motatan sailkatzen dira: Schamberg's purpura, Majocchi purpura, lichen aureus, Gougerot‑Blum purpura, eta Doucas eta Kapetanakis‑en eczematoid‑itzala purpura. Schamberg disease (SD) Schamberg‑en pigmentazio progresiboaren dermatosia, purpura pigmentosa progressiva, eta Schamberg's purpura izenez ere ezagutzen da. Batez ere gizonezkoetan agertzen da eta normalean beheko hanketan agertzen da, baina izterretan, ipurmasailetan, enborrean edo besoetan ere gerta daiteke.
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.

PPD duten 113 pazienteri buruzko informazioa aztertu da, ikerketa honetarako azaleko biopsia egin dieten 38 pazientetan barne. Mota kliniko ohikoena Schamberg‑en gaixotasuna izan zen (60,5 %). PPDrekin batera beste baldintza batzuk hipertensioa (15,8 %), diabetesa (10,5 %) eta beste batzuk izan ziren. Medikamentuen historiak estatinak (13,2 %), beta‑blokeatzaileak (10,5 %) eta beste batzuk agertu zituzten. PPDrekin erlazionatutako faktore posibleen artean goiko arnas infekzioa (5,3 %), presio ortostatiko handia (2,6 %) eta ariketa gogorra (2,6 %) zutik egotea izan ziren. Tratamendua 36 pazienteri (94,7 %) eman zitzaien: oral antihistamines, pentoxifylline, topical steroids, eta/edo 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.
