Abstract
OBJECTIVE
To investigate the clinicopathological features of primary intravascular large B-cell lymphoma (IVLBCL) of the lung.
METHODS
Histopathological and clinical data based on lung biopsy were analyzed and used to diagnose a patient with IVLBCL of the lung.
RESULTS
Fever and respiratory symptoms were the main presentations, lung biopsy revealed lymphoma cells in the lumen of small blood vessels. Tumor cells expressed Bcl-2, the Bcl-6, CD20, Ki67, MUM-1, Pax5, CD, CD30, and vascular endothelial CD34.
CONCLUSIONS
Primary pulmonary IVLBCL of the lung is extremely rare, on chest CT it manifests as diffuse ground glass shadow, or nodular consolidations in the lung, lactate dehydrogenase and C-reactive protein was found to increase, fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) is an important and significant diagnostic modality in its early diagnosis. Also, bronchial lung biopsy has the advantage of less trauma and high sensitive rate. R-CHOP is the main treatment for lung primary pulmonary IVLBCL of the lung; however, its prognosis is relatively poor.
