Intravascular large B-cell lymphoma colonizing in senile hemangioma: a case report and proposal of possible diagnostic strategy for intravascular lymphoma.

摘要

Intravascular large B-cell lymphoma (IVLBCL) is a relatively rare subtype of extranodal malignant large B-cell lymphoma characterized by the selective growth of lymphoma cells within the lumina of the vessels and is included as a specific disease entity in the World Health Organization Classification. IVLBCL is often difficult to diagnose because of the heterogeneity of clinical symptoms, such as fever, neurological abnormalities and respiratory distress, and the lack of lymphadenopathy and mass formation. Therefore, almost half of the patients with IVLBCL were diagnosed postmortem and the poor prognosis of IVLBCL may be related to the delay in diagnosis and treatment.
