Intravascular lymphoma: the oncologist's "great imitator"

Area of Science:

• Hematology
• Oncology
• Pathology

Background:

• Intravascular lymphoma (IVL) is a rare extranodal diffuse large B-cell lymphoma.
• Characterized by lymphocyte proliferation within small blood vessels, sparing surrounding tissue.
• Clinical presentation varies based on organ involvement, frequently affecting the central nervous system and skin.

Purpose of the Study:

• To provide a concise, up-to-date summary of intravascular lymphoma.
• To highlight diagnostic challenges and advances.
• To discuss current and future therapeutic strategies.

Main Methods:

• Review of existing literature on intravascular lymphoma.
• Analysis of diagnostic methods including biopsy, imaging, and immunohistochemistry.
• Synthesis of information on clinical presentation and treatment outcomes.

Main Results:

• IVL diagnosis is often delayed or postmortem due to rarity and varied presentation.
• Surgical biopsy remains the primary diagnostic method.
• Advances in imaging and immunohistochemistry are improving antemortem diagnosis rates.

Conclusions:

• While aggressive therapy can cure some IVL patients, improved outcomes require further research.
• Novel treatment strategies are essential for managing this rare lymphoma.
• Basic science insights may offer future therapeutic avenues.
