Kaposi氏肉瘤是一种进行性,多中心性病变,常侵犯皮肤、淋巴结和腹腔脏器。文献报告35%的艾滋病患者可发生Kaposi氏肉瘤。为了明确艾滋病患者肺部Kaposi氏肉瘤X线表现的组织学基础,作者对乔治·华盛顿大学医学院1981年9月至1985年7月发现的全部艾滋病患者的外科病理记录进行了回顾性检查,对经支气管穿刺和开胸活检的病理标本进行了细菌、真菌、分枝杆菌以及病毒染色和培养,排除了在诊断性活检时有并发机遇性感染的患者。对其中9例无合并感染的艾滋病肺 Kaposi’s sarcoma is a progressive, multicentric disease, often invading the skin, lymph nodes and abdominal organs. In the literature, 35% of AIDS patients may develop Kaposi’s sarcoma. In order to clarify the histological basis for the X-ray findings of Kaposi’s sarcoma in the lungs of AIDS patients, the authors performed a retrospective review of the surgical pathology records of all AIDS patients found at the George Washington University School of Medicine from September 1981 to July 1985, Bacteria, fungi, mycobacteria, and viruses were stained and cultured by bronchial and thoracotomy biopsies, excluding patients with opportunistic infections on diagnostic biopsies. Nine cases of AIDS-free lung infection
