폐문 임파절 종대를 동반한 양측성 미만성 폐침윤

Non-Hodgkin's lymphoma arising in lung comprises 0.5% of primary lung tumor and 3% of extranodal lymphoma. The most common radiographic abnormalities of pulmonary lymphoma include pulmonary nodule and consolidation, but hilar lymphadenopathy is rarely observed Recently we experienced primary pulmonary T-cell lymphoma presenting with bilateral hilar lymphadenopathies and diffuse pulmonary infiltration A 39-year-old man was admitted to the hospital because of fever, cough, and severe dyspnea. Chest PA obtained on admission revealed bilateral hilar lymphadenopathies and diffuse bilateral pulmonary infiltration. The diagnosis of sarcoidosis was strongly suggested and empirical treatment with corticosteroids resulted in dramatic clinical and radiological improvement for a short time. Eventually, CT-guided lung biopsy was performed and the specimen disclosed primary pulmonary Non-Hodgkin's lymphoma of T-cell origin, diffuse small lymphocytic with focal plasmacytoid differentiation.

폐임파종은 매우 드문 질환으로 흉부 X-선상 단일 결절이나 미만성 폐침윤의 소견을 보이며 폐문 임파절 종대를 보이는 경우는 드물다. 저자들은 발열과 기침, 체중감소를 주소로 내원하여 흉부 X-선상 양측 폐문 임파절 종대와 미만성 폐침윤을 보인 환자에서 전산화단층촬영 유도하 생검상 T-세포 폐임파종으로 진단한 1예를 경험하였기에 문헌 고찰과 함께 보고하는 바이다.
