Fine Needle Aspiration (FNA) Cytology of Lymphoid Lesions; Definition and the Outcome of the Atypical/suspicious Diagnostic Category: Study of 34 Cases.
Journal Title: Journal of Hematology and Oncology Research - Year 2014, Vol 1, Issue 1
Abstract
Context: Fine needle aspiration cytology (FNA) is increasingly replacing excisional lymph node biopsy in the assessment of various lymphoid lesions. Recent changes in the classification of non-Hodgkin’s lymphoma, namely the WHO (World Health Organization) Classification of Tumors of Haematopoietic and Lymphoid Tissues has considerably expanded its classification of lymphomas based on the molecular and cytogenetic profiling and immunophenotyping . FNA diagnosis includes varied cytomorphologic diagnostic categories; one of them is the atypical/suspicious. Objective: The atypical/suspicious category constitutes about 20 % of all cases studied by FNA cytology. The objective of this study is to determine the definition and the outcome of this unique category. Design: A retrospective analysis of 34 fine needle aspirations with the diagnosis of atypical/suspicious cases were obtained during the period between 1995 –2000, and the histological and/or clinical follow-up was performed. Results: Flow cytometry was performed on all of the atypical/suspicious lesions. It was positive/diagnostic in 16 (47%) and negative in 18(53%) cases. Excisional follow-up biopsy was obtained in 30 cases. Of these 7(21%) confirmed to be negative, 17(50%) Non-Hodgkin’s lymphoma and 6 (18%) Hodgkin’s Lymphoma. Conclusion: The atypical/suspicious category by fine needle aspiration is a crucial diagnosis as it has proved to represent some type of lymphoma in about two third (68%) of cases.
