Malignant peritoneal mesothelioma (MPM) is a rare malignant tumor with peritoneal thickening. Tuberculous peritonitis also shows peritoneal thickening, so differentiating between the two is important but difficult if latent tuberculosis infection (LTBI) is present. We herein report a patient with MPM and LTBI. A 79-year-old man was diagnosed with peritoneal thickening on computed tomography. Interferon gamma release assay (IGRA) results were positive, suggesting tuberculous peritonitis. He underwent a laparoscopic omental biopsy and was diagnosed with MPM, which can occur together with LTBI. If peritoneal thickening is observed, an IGRA should be performed early, and the possibility of LTBI should be considered.
恶性腹膜间皮瘤（MPM）是一种伴有腹膜增厚的罕见恶性肿瘤。结核性腹膜炎也表现为腹膜增厚，因此区分两者很重要，但如果存在潜伏性结核感染（LTBI）则很难区分。我们在此报告一例患有MPM和LTBI的患者。一名79岁男性在计算机断层扫描中被诊断为腹膜增厚。干扰素γ释放试验（IGRA）结果呈阳性，提示结核性腹膜炎。他接受了腹腔镜网膜活检，被诊断为MPM，MPM可与LTBI同时发生。如果观察到腹膜增厚，应尽早进行IGRA检查，并考虑LTBI的可能性。
