Abstract

症例は72歳, 男性. 検診で胸部X線上両肺に多発する浸潤影, びまん性に散在する線状網状影を指摘された. 自覚症状はなかった. 経気管支肺生検で悪性リンパ腫が疑われたため開胸肺生検を施行し, 肺悪性リンパ腫, LSG分類の diffuse small cell type, B cell type と診断した. 切除肺の組織標本では, 異型リンパ球様細胞が肺胞に充満し, 又, 気管支, 血管, 胸膜周囲のリンパ路に沿って浸潤, 増殖している像が認められた. これらの所見が全肺野に多発性に形成されたために胸部X線像が特異な所見を呈したと考えられた. 胸部X線で本症例のような多発する浸潤影, びまん性に散在する線状網状影を呈する症例を診断する際には, 悪性リンパ腫も鑑別診断の1つに挙げるべきと考えられた.

A 72-year-old asymptomatic man was admitted to our hospital with abnormal chest radiographic findings: bilateral diffuse linear, reticular, and consolidated shodows. Malignant lymphoma (diffuse small-cell B-cell lymphoma) was diagnosed histologically after an open lung biopsy and was confirmed by a genetic examination. The lymphoma cells had infiltrated widely in various regions of the lung, including the alveolar spaces and walls, the bronchial and vascular spaces, and the pleura. This diffusion of the lymphoma cells might have accounted for the chest X-ray findings. Malignant pulmonary lymphoma should be included in the differential diagnosis patients with diffuse linear, reticular, and consolidated shadows on chest X-ray films.
