The 8p12 myeloproliferative syndrome

Area of Science:

• Hematology
• Oncology
• Genetics

Background:

• Concurrent myeloproliferative and lymphoproliferative disorders are rare.
• Leukaemia-lymphoma syndrome presents diagnostic challenges due to overlapping clinical features.

Purpose of the Study:

• To report a unique case of concurrent leukaemia-lymphoma syndrome.
• To highlight the diagnostic difficulties and importance of molecular analysis in 8p12 myeloproliferative syndrome / stem cell leukaemia-lymphoma syndrome.

Main Methods:

• Case report analysis.
• Bone marrow chromosome analysis to identify karyotype and gene translocations (FGFR1).
• Clinical management with hydroxyurea, allopurinol, and blood component therapy.

Main Results:

• A patient presented with BCR/ABL-negative myeloproliferative disease, eosinophilia, lymphoma, and FGFR1 gene translocations (t(8;9)).
• The patient was diagnosed with 8p12 myeloproliferative syndrome / stem cell leukaemia-lymphoma syndrome.
• The patient died from intracerebral hemorrhage secondary to severe thrombocytopenia.

Conclusions:

• The clinical presentation overlap between lymphomas and 8p12 myeloproliferative syndrome / stem cell leukaemia-lymphoma syndrome can delay diagnosis.
• Accurate clinical and molecular diagnosis is essential due to the aggressive nature of this condition.
