A Case Report of the Primary Lung Lymphoma

폐 종괴로 발현한 원발성 폐림프종 치험 1예

The primary lymphoma in the lung is very rare. Moot of the primary pulmonary lymphomas, which represent 3-4 % of extra-nodal lymphomas, are low-grade B-cell lymphoma. The low-grade B-cell lymphomas progress slowly and the prognosis of these are more favorable than that of the nodal lymphomas. However, high-grade forms progress rapidly with more severe course. The diagnosis of primary pulmonary lymphomas generally relies on the histopathologic findings of lung specimens obtained by surgical excision of the lesions or open-lung biopsy. Recently, less aggressive biopsies(transbronchial, transthoracic) and/or immunocyto-chemical, immunochemical and gene rearrangement studies on materials obtained by bronchoalveolar lavage have been used occasionally. The treatment of the primary pulmonary lymphomas has not been precisely codified. Several clinical data suggest that limited surgery or non-aggressive chemotherapy can provide long-term survival in patients with such slowly developing neoplasm, and demonstrated the need for the development of noninvasive diagnootic methods. In this study, we report a case of high-grade B-cell lymphoma of the lung which was treated with combination chemotherapy.

폐의 원발성 림프종은 드문 질환으로 저등급 B세포 림프종이 주를 이루며 경과와 예후가 양호한 반면 고등급 B세포 림프종은 경과와 예후가 저등급 B세포 림프종에 비해 좋지 않다. 그리고 그 치료에 대해서는 아직 정확히 제시된 바가 없고 치료경험들에 대한 증례 보고들이 몇몇 있었다. 본 저자는 폐내 종괴와 흉막삼출이 있었던 환자에서 흉막침범 소견이 있었으며 흉막생검을 통해 비교적 급속한 진행경과를 보이는 diffuse large B cell 림프종을 진단하였으며 cyclophosphamide, epirubicin, vincristine 그리고 prednisolone의 복합화학요법을 6회 시행후 종괴가 소실된 부분관해를 치험하였기에 문헌고찰과 함께 증례보고 하는 바이다.
