Castleman disease diagnosis relies on distinguishing subtypes and careful pathological analysis. Pathologists play a key role in identifying Castleman disease, especially the idiopathic multicentric form, through HHV8 testing and ruling out other conditions.

Area of Science:

  • Pathology
  • Oncology
  • Infectious Disease

Context:

  • Castleman disease presents with three histological subtypes: vascular hyaline (HV), plasmacytic (PV), and mixed.
  • Unicentric and HHV8+ multicentric Castleman disease are diagnosed more readily than the idiopathic multicentric form.
  • Idiopathic multicentric Castleman disease diagnosis is challenging due to its overlap with infectious, tumoral, and dysimmune conditions.

Purpose:

  • To outline the diagnostic challenges and pathological roles in identifying Castleman disease subtypes.
  • To emphasize the necessity of anatomoclinical correlation for accurate diagnosis.
  • To highlight the importance of HHV8 testing, phenotyping, and molecular analysis in differential diagnosis.

Summary:

  • Castleman disease subtypes include vascular hyaline, plasmacytic, and mixed.

  • Pathological examination is crucial for diagnosing Castleman disease, particularly the idiopathic multicentric form.
  • Key diagnostic steps include HHV8 testing, phenotyping, and clonality analysis to exclude lymphoma and infections.

    • Impact:

    • Improved diagnostic accuracy for Castleman disease, especially the idiopathic multicentric form.
    • Enhanced understanding of the pathologist's role in differentiating Castleman disease from other pathologies.
    • Facilitates timely and appropriate patient management by clarifying diagnostic pathways.
