A solitary lung nodule (SLN) is seen in 1 in 500 chest radiographs. Benign causes include infectious granulomas and hamartomas, and less commonly, rheumatoid nodules, intrapulmonary lymph nodes and sarcoidosis. Bronchogenic carcinoma and solitary pulmonary metastases are found in 35% and 23% of SLN's respectively. Primary pulmonary non-Hodgkins lymphoma is a rare disease, constituting 0.4% of all lymphomas. We present a case of primary pulmonary non-Hodgkins lymphoma which presented as a SLN in an 87-year old lady with a smoking history of 50 pack years.
在每500例胸部X光片中就有1例可见孤立性肺结节（SLN）。良性病因包括感染性肉芽肿和错构瘤，较少见的有类风湿结节、肺内淋巴结和结节病。在SLN病例中，分别有35%和23%被发现为支气管源性癌和孤立性肺转移瘤。原发性肺非霍奇金淋巴瘤是一种罕见疾病，占所有淋巴瘤的0.4%。我们报告一例原发性肺非霍奇金淋巴瘤病例，该病例表现为一名有50年吸烟史的87岁女性的SLN。
