Mucosa associated lymphoid tissue (MALT) lymphoma of the orbit is rare, often indolent, but can recur, and spread to extra-nodal sites. Pleural and retroperitoneum recurrences of MALT lymphoma are rare.
A 65-year-old man was referred to our hospital due to right pleural effusion and difficulty in breathing. He had a medical history of having undergone surgery for MALT lymphoma of the left orbit. A chest computed tomography (CT) scan showed right pleural thickness, pleural effusion, and a retroperitoneal mass, spreading from the muscular layer to the subcutaneous layer. The thickened pleural lesion was surgically biopsied and diagnosed as a recurrence of MALT lymphoma.
Pleural effusion should be carefully examined and monitored for the possibility of recurrence in MALT lymphoma patients.
眼附属淋巴组织（MALT）淋巴瘤较为罕见，通常为惰性，但可复发并扩散至结外部位。MALT 淋巴瘤胸膜和腹膜后复发较为罕见。
一名 65 岁男性因右侧胸腔积液和呼吸困难被转诊至我院。他曾有左眼 MALT 淋巴瘤手术史。胸部计算机断层扫描（CT）显示右侧胸腔增厚、胸腔积液和腹膜后肿块，从肌肉层向皮下层扩散。增厚的胸膜病变被手术活检，并诊断为 MALT 淋巴瘤复发。
对于 MALT 淋巴瘤患者，应仔细检查胸腔积液并监测其复发的可能性。
