A Rare Clinical Case of Secondary Central Nervous System Involvement without Transformation in Hairy Cell Leukemia: A Case Report and Literature Review.
Introduction: Hairy cell leukemia (HCL) is an indolent B-cell lymphoma characterized by a specific genetic mutation, BRAF V600E, which affects the specific morphology and oncogenesis. For HCL, few reports regarding secondary central nervous system involvement (SCNSI) are available. Herein, we present the case of an 80-year-old woman who had a relapse of HCL with SCNSI.
Case presentation: The diagnosis of HCL was made in June 2015 after identifying BRAF V600E proteins by immunohistochemical analysis, and the disease was then controlled for 6 years by employing chemoimmunotherapy. In February 2021, the patient was admitted with neurological symptoms such as dizziness. Magnetic resonance imaging of the brain showed abnormal enhancement in the cerebrum, and cerebrospinal fluid analysis revealed neoplastic cells without transformation into large cells. Thus, the patient was diagnosed as having SCNSI in HCL.
Conclusion: We report a case of a rare clinical presentation of SCNSI in HCL with literature review.
期刊介绍：
''Acta Haematologica'' is a well-established and internationally recognized clinically-oriented journal featuring balanced, wide-ranging coverage of current hematology research. A wealth of information on such problems as anemia, leukemia, lymphoma, multiple myeloma, hereditary disorders, blood coagulation, growth factors, hematopoiesis and differentiation is contained in first-rate basic and clinical papers some of which are accompanied by editorial comments by eminent experts. These are supplemented by short state-of-the-art communications, reviews and correspondence as well as occasional special issues devoted to ‘hot topics’ in hematology. These will keep the practicing hematologist well informed of the new developments in the field.
