Diffuse Large B-Cell Lymphoma Associated with a Chronic Inflammatory Condition Induced by Metallic Implants: A Case...

Area of Science:

• Oncology
• Pathology
• Radiology

Background:

• Chronic inflammation associated with metallic implants is a known risk factor for developing diffuse large B-cell lymphoma (DLBCL).
• Metal ions are implicated in the pathogenesis of lymphoma.
• DLBCL can manifest as a rare complication following metallic implant insertion.

Observation:

• A rare case of DLBCL occurred in a patient with a proximal tibial metallic implant in place for 15 months.
• Radiological imaging (ultrasound and MRI) revealed a large extraosseous soft-tissue mass and bone marrow involvement.
• Bone destruction was not a prominent feature in the observed case.

Findings:

• The case highlights the challenge in distinguishing implant-associated lymphoma from other periprosthetic lesions.
• Misdiagnosis can lead to suboptimal or incorrect treatment strategies.
• Radiological findings of large soft-tissue masses and bone marrow involvement without significant bone destruction are key indicators.

Implications:

• Accurate differentiation is critical for appropriate patient management and treatment.
• Increased awareness among clinicians is needed to consider lymphoma in patients with metallic implants presenting with unusual soft tissue masses.
• Further research into the mechanisms of implant-associated lymphomagenesis may improve diagnostic and therapeutic approaches.
