Primary pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma is a type of non-Hodgkin lymphoma, and it occurs frequently in the stomach and rarely in the lungs. They are rarely taken into consideration in the differential diagnosis of lung lesions. MALT lymphomas affecting the lung show various styles on chest CT, which range from typical nodules or areas of consolidation to findings that are extremely rare, such as a progressive ground glass opacity (GGO) that never been reported before especially in a postoperative colon cancer patient. The postoperative pathologic diagnosis of the progressive GGO was extranodal marginal zone B-cell lymphoma of MALT. And during 2-year follow-up, the patient was in good condition and there was no sign of recurrence. This case would enrich the manifestations and increase the understanding in MALT, and inappropriate treatment would be avoided.
原发性肺黏膜相关淋巴组织（MALT）淋巴瘤是一种非霍奇金淋巴瘤，常见于胃部，很少发生于肺部。在肺部病变的鉴别诊断中很少考虑到它们。累及肺部的MALT淋巴瘤在胸部CT上表现多样，从典型的结节或实变区域到极为罕见的表现，如一种此前从未报道过的进行性磨玻璃影（GGO），尤其是在一名结肠癌术后患者中。该进行性GGO的术后病理诊断为MALT型结外边缘区B细胞淋巴瘤。在2年的随访期间，患者状况良好，无复发迹象。该病例将丰富MALT淋巴瘤的表现并增进对其的认识，同时避免不恰当的治疗。
