Intravascular Large B-cell Lymphoma within Duodenal Gastrointestinal Stromal Tumor / 대한췌담도학회지

ABSTRACT

Intravascular large B-cell lymphoma (IVLBCL) is a rare disease of intravascular growth of malignant lymphocytes without an obvious extravascular tumor mass or existence in peripheral blood. It has poor prognosis due to its aggressive behavior and rapid systemic dissemination. But there is no pathognomonic finding, diagnosis of IVLBCL is still challenging. Here we report a case of IVLBCL found within a resected specimen of duodenal gastrointestinal stromal tumor.
