FOUR CASES OF WALDENSTROEM'S MACROGLOBULINAEMIA

Area of Science:

• Hematology
• Oncology
• Ophthalmology

Background:

• Waldenström's macroglobulinaemia is a rare lymphoproliferative disorder.
• Understanding its diverse clinical and pathological manifestations is crucial for diagnosis and management.

Purpose of the Study:

• To describe the clinical course and pathological features of four Waldenström's macroglobulinaemia cases.
• To investigate potential associations with other neoplastic conditions.
• To examine ocular findings and discuss the etiology of anemia.

Main Methods:

• Case study analysis of four patients with Waldenström's macroglobulinaemia.
• Histopathological examination of affected tissues.
• Retinal trypsin digest preparations in select cases.
• Assessment of erythrophagocytosis and autoantibody-mediated hemolysis.

Main Results:

• Two cases showed associations with other malignancies: localized bronchus carcinoma and chromophobe adenoma.
• Retinal findings varied, with severe retinopathy in one case and no clinical ocular disease in another.
• Erythrophagocytosis was present to varying degrees and not directly proportional to serum macroglobulin levels.
• Autoantibody-mediated hemolysis was not detected.

Conclusions:

• The cytological and histological features of Waldenström's macroglobulinaemia are distinctive.
• These features are valuable in the differential diagnosis of the disorder.
• Associated conditions and specific pathological findings like erythrophagocytosis warrant careful consideration.
