- BACKGROUND: The evaluation of lymph nodes (LN) by fine-needle aspiration cytology (FNAC) is routinely used in many institutions but it is not uniformly accepted mainly because of the lack of guidelines and a cytopathological diagnostic classification. A committee of cytopathologists has developed a system of performance, classification, and reporting for LN-FNAC. METHODS: The committee members prepared a document that has circulated among them five times; the final text has been approved by all the participants. It is based on a review of the international literature and on the expertise of the members. The system integrates clinical and imaging data with cytopathological features and ancillary techniques. The project has received the endorsement and patronage of the International Academy of Cytology and the European Federation of the Cytology Societies. RESULTS: Clinical, imaging, and serological data of lymphadenopathies, indications for LN-FNAC, technical procedures, and ancillary techniques are evaluated with specific recommendations. The reporting system includes two diagnostic levels. The first should provide basic diagnostic information and includes five categories: inadequate/insufficient, benign, atypical lymphoid cells of undetermined/uncertain significance, suspicious, and malignant. For each category, specific recommendations are provided. The second diagnostic level, when achievable, should produce the identification of specific benign or malignant entities and additional information by utilizing ancillary testing. CONCLUSION: The authors believe that the introduction of this system for performing and reporting LN-FNAC may improve the quality of the procedure, the report, and the communication between cytopathologists and the clinicians. This system may lead to a greater acceptance and utilization of LN-FNAC and to a better interdisciplinary understanding of the results of this procedure.

Forskningsöversikt (refereegranskat)abstract
- Fine needle aspiration biopsy cytopathology (FNAC) of lymph nodes is a very common, inexpensive, and rapid diagnostic procedure and can lead to the accurate and timely diagnosis of one of the wide range of pathological processes that involve lymph nodes. These diagnoses include specific reactive processes, specific infections such as tuberculosis, metastatic carcinomas and melanomas, and some lymphomas. The FNAC effectively triages the lymph node material, but the initial diagnosis often requires ancillary testing as a second diagnostic step to make a specific diagnosis, such as the particular infectious agent, the type of lymphoma or Hodgkin lymphoma, or the specific type of metastatic malignancy. An international group of cytopathologists have begun the process of developing a system for the standardized reporting of lymph node FNAC. The group is addressing the pre-analytical issues related to the FNAC, including the role of clinical information and the use of ultrasound, and developing a structure of reporting categories based on the cytopathological findings linked to management recommendations. The basis of the system is the integration of the FNAC with the clinical setting, imaging, and ancillary tests that utilize the FNAC material, to produce a final report that will enhance patient care.
