Primary lung lymphoma (PLL) is a rare unilateral or bilateral lung disorder that is challenging to diagnose solely based on clinical and radiological presentation. PLL may be misdiagnosed as pneumonia or a lung tumor due to non-specific findings. PLL is most frequently a mucosa-associated lymphoid tissue (MALT) lymphoma, a type of extranodal low-grade B-cell lymphoma most commonly discovered in the gastrointestinal tract. PLL should be considered in the differential diagnosis of non-resolving pneumonias. Herein we present a case of an 84-year-old patient discovered to have a primary pulmonary MALT lymphoma presenting as a non-resolving pneumonia causing a clinical challenge.
原发性肺淋巴瘤（PLL）是一种罕见的单侧或双侧肺部疾病，仅根据临床和影像学表现进行诊断具有挑战性。由于表现不具特异性，PLL可能被误诊为肺炎或肺部肿瘤。PLL最常见的是黏膜相关淋巴组织（MALT）淋巴瘤，这是一种结外低度B细胞淋巴瘤，最常出现在胃肠道。在鉴别诊断不愈性肺炎时应考虑PLL。在此，我们报告一例84岁患者，其被发现患有原发性肺MALT淋巴瘤，表现为不愈性肺炎，带来了临床挑战。
