Five patients with chronic pigmented purpura associated with odontogenic infection are described. Four patients had Schamberg's disease, and one had itching purpura. These patients were resistant to topical corticosteroid treatment, but appearance of purpuric spots ceased after treatment for periodontitis, pulpitis, or both. No circulating immune complexes were detected, and neither immunoglobulin nor complement was deposited in the papillary vessels of the skin. Odontogenic infection might be one of the precipitating factors for chronic pigmented purpura.
本文描述了5例与牙源性感染相关的慢性色素性紫癜患者。其中4例患有施奈德病，1例患有瘙痒性紫癜。这些患者对局部皮质类固醇治疗有抵抗，但在治疗牙周炎、牙髓炎或两者后紫癜斑点消失。未检测到循环免疫复合物，皮肤乳头血管中也未发现免疫球蛋白或补体沉积。牙源性感染可能是慢性色素性紫癜的诱发因素之一。
