Diagnostic Role of Bone Marrow Examination in Pyrexia of Unknown Origin

Diagnostic Value and Yield

• The National Comprehensive Cancer Network recommends that bone marrow biopsy is an essential component of staging in patients with suspected lymphoma, particularly for detecting lymphomas 1, 2

Specific Disease Considerations

• The National Comprehensive Cancer Network suggests that in patients with suspected lymphoma, bone marrow biopsy is crucial for diagnosis and staging, with a high diagnostic yield 1, 2
• The National Comprehensive Cancer Network recommends bone marrow examination for diagnosis and prognostic assessment in multiple myeloma 3, 4
• The Mayo Clinic suggests that bone marrow histology is a key diagnostic feature in polycythemia vera when combined with serum erythropoietin levels 5, 6
• The National Comprehensive Cancer Network recommends that routine bone marrow biopsy may be omitted in Hodgkin lymphoma if PET scan is negative or shows homogenous bone marrow uptake 7

Diagnostic Approach to Pyrexia of Unknown Origin

Indications and Diagnostic Yield

• The National Comprehensive Cancer Network recommends that in patients with suspected Hodgkin lymphoma, routine bone marrow biopsy may be omitted if PET scan is negative or shows homogeneous bone marrow uptake 8
• In typical cases of lymphomatoid papulosis (LYP) with absence of palpable enlarged lymph nodes, absence of hepatosplenomegaly, normal laboratory tests, and absence of B symptoms, bone marrow examination may not be necessary, as suggested by guidelines from the American Society of Hematology 9
