Clinical and pathological analysis of intravascular large B-cell lymphoma of the prostate

In patients with benign prostate hyperplasia, proliferative blood vessels are found in the interstitium, and there is an accumulation of proliferative large cells in the lumen, which do not resemble endothelial cells, epithelial cells, tissue cells, or inflammatory cells. Pathologists should consider the possibility of intravascular large B-cell lymphoma and conduct immunohistochemical staining for large B-cell lymphoma. Primary intravascular large B-cell lymphoma of the prostate should be diagnosed after ruling out metastatic tumors.
