Background: Intravascular large B-cell lymphoma (IVLBCL) is a rare subtype of extranodal B-cell lymphoma, which has traditionally been associated with poor outcomes. Despite increasing recognition, IVLBCL requires a high degree of clinical suspicion on the part of the clinician for its diagnosis. Case Series: We present four patient cases: A 69-year-old female with constitutional symptoms and cognitive decline; a 78-year-old female with kidney injury and constitutional symptoms whose disease rapidly progressed to multiorgan failure and death; a 70-year-old asymptomatic female with an incidentally found, enlarged thyroid; and a 63-year-old male with cytopenia and constitutional symptoms. Retrospective chart analysis was performed on these four patients diagnosed with IVLBCL at our Institute to identify the pathognomonic features of the disease and compare these to the published evidence. IVLBCL has a heterogeneous presentation, as seen in our four patients. The disease is characterized by the exclusive presence of malignant cells inside the blood vessels and lack of organ infiltration. Traditional preliminary diagnostic modalities such as imaging are usually inconclusive, given the paucity of lymphomatous aggregates. A bone marrow biopsy, random skin biopsies, or a focal organ biopsy in appropriate cases is required for diagnosis. Immunosuppression might play a role in the pathogenesis. Timely initiation of aggressive cancer-directed therapy was associated with improved outcomes. Monitoring for disease response and relapse continues to be a challenge. Conclusion: Our mini-series highlights the significance of timely diagnosis and intervention in IVLBCL and emphasizes the importance of further research to determine its association with immunosuppression.
