Summary

Plasmablastic lymphoma, a rare HIV-associated non-Hodgkin lymphoma, often affects the oral cavity and can be misdiagnosed. Early recognition is crucial for accurate diagnosis and management of this aggressive lymphoma.

Area of Science:

  • Oncology
  • Virology
  • Pathology

Background:

  • Plasmablastic lymphoma (PBL) is a rare, aggressive non-Hodgkin lymphoma.
  • It is strongly associated with human immunodeficiency virus (HIV) infection.
  • PBL typically presents as a large B-cell lymphoma with a predilection for the oral cavity.

Observation:

  • Clinically, PBL can be mistaken for Kaposi's sarcoma or odontogenic cellulitis.
  • Epstein-Barr virus (EBV) and human herpesvirus 8 (HHV-8) are frequently detected in PBL.
  • The neoplastic cells may not express conventional B-cell markers, complicating diagnosis.

Findings:

  • This entity can be misdiagnosed as non-lymphoid malignancies, particularly Kaposi's sarcoma.
  • The lack of conventional B-cell markers poses a diagnostic challenge.

  • Prognosis for high-grade lymphomas in patients with acquired immunodeficiency syndrome (AIDS) remains poor.

    • Implications:

    • Increased awareness of PBL is essential to prevent diagnostic errors.
    • Distinguishing PBL from other oral lesions is critical for appropriate treatment.
    • Further research into the pathogenesis and treatment of PBL in HIV-infected individuals is warranted.
