[Clonal diseases in the border zone rheumatology/hematology]

Area of Science:

• Rheumatology
• Immunology
• Hematology

Context:

• Chronic inflammation and immunoregulation disorders are hallmarks of inflammatory rheumatic diseases.
• These conditions also contribute to the development and outcomes of plasma cell dyscrasias with associated gammopathy.

Purpose:

• To highlight the importance of considering monoclonal gammopathy of undetermined significance (MGUS) in patients presenting with unexplained rheumatological symptoms.
• To emphasize the necessity of thorough patient examination for differentiating between MGUS, monoclonal gammopathy of clinical significance (MGCS), and multiple myeloma.

Summary:

• Inflammatory rheumatic diseases and plasma cell dyscrasias share common features of chronic inflammation and immunoregulation issues.
• Unexplained rheumatological symptoms warrant consideration of underlying MGUS.
• Distinguishing between MGUS, MGCS, and multiple myeloma requires comprehensive patient evaluation.

Impact:

• Improved diagnostic strategies for patients with complex rheumatological presentations.
• Enhanced understanding of the interplay between inflammatory diseases and plasma cell disorders.
• Facilitation of timely and accurate diagnosis, leading to appropriate patient management and treatment stratification.
