Abstract
BACKGROUND Fine-needle aspiration (FNA) has been reported since 1912 beginning with the use of trocars and other specialized instruments that were impractical. Since then, FNA has proven to be a successful alternative technique to excisional biopsy for some assays despite a few limitations. METHODS In this study, we compared four different techniques for FNA in rhesus macaques by evaluating total live cells recovered and cell viability using a standard 6 mL syringe and 1.5-inch 22-gauge needle. RESULTS Technique B which was the only technique in which the needle was removed from the syringe after collection of the sample to allow forced air through the needle to expel the contents into media followed by flushing of the syringe and needle resulted in the highest total cell count and second highest cell viability in recovered cells. CONCLUSION Based on our results, Technique B appears to be the superior method.

Abstract
Optimal breast care requires a multidisciplinary and integrated approach, including appropriate processes and communication between the radiology and pathology departments. It is important for breast radiologists to have an understanding of the important events that occur between the time a percutaneous biopsy sample is obtained and the point at which the final pathology report is issued. This article reviews the essential processes from breast biopsy through to pathology diagnosis, including the general pathology workflow, tissue preparation, immunohistochemical staining, and pathologic reporting. Upon completion of this educational article, participants will have gained an understanding of the essential steps in the pathology workflow. This article will also highlight the important clinical information a radiologist should provide to the pathologist to ensure the most accurate and clinically relevant diagnosis. This clinical information includes the BI-RADS assessment category, the type of imaging finding that was targeted for biopsy (particularly when there are calcifications), the location of the targeted lesion relative to other findings, and other pertinent patient history.

Abstract
Aims and Objectives Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has emerged as a precise modality for tissue sampling of mediastinal and hilar lesions adjacent to the proximal airway. This study aims to determine the diagnostic efficacy, sensitivity, and specificity of rapid-on site evaluation (ROSE) in EBUS-TBNA. Materials and Methods This is a retrospective study that included 100 patients who underwent EBUS-TBNA of paratracheal and mediastinal lymph nodes in a tertiary care hospital in South India between March 2018 and March 2020. After the procedure, the diagnostic yield from the nodes sampled was transferred to slides that were stained with rapid hematoxylin and eosin (H and E), and then onsite evaluation was done. The tissue derived was also processed for histopathologic examination in all cases. ROSE was performed to assess sample adequacy and to arrive at a preliminary diagnosis. In patients suspected of tuberculosis, the sample was collected for GeneXpert evaluation as well. Results Of the 100 cases studied, 51 were males and 49 were females. The age distribution was between 3 and 78 years. Forty-seven cases were diagnosed as granulomatous lymphadenitis, 13 as metastatic malignancies, 33 as reactive lymphadenitis, 3 as atypical cells, and 1 case was diagnosed as a cystic lesion. The diagnostic yield was not adequate for evaluation in three cases. Diagnostic yield was obtained in the first two passes where the lymph nodes were more than 2 cm in size. More diagnostic passes were required in lymph nodes less than 2 cm and those located between and adjacent to major vessels. The onsite diagnosis was correlated with the final histopathologic diagnosis. Conclusion ROSE serves as a useful adjunct to reduce procedure time and enhance sample collection and triaging, and reduces the need for further invasive testing.

Processing and Reporting of Cytology Specimens from Mediastinal Lymph Nodes Collected using Endobronchial Ultrasound-Guided Transbronchial Needle Aspiration: A State-of-the-Art Review. J Cytol 2020; 37:72-81. [PMID: 32606494 PMCID: PMC7315917 DOI: 10.4103/joc.joc_100_19] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2019] [Revised: 12/05/2019] [Accepted: 12/25/2019] [Indexed: 12/12/2022] Open
Abstract
Endobronchial ultrasound (EBUS)-guided transbronchial needle aspiration (TBNA) is presently the preferred modality for sampling mediastinal lymph nodes. There is an unmet need for standardization of processing and reporting of cytology specimens obtained by EBUS-TBNA. The manuscript is a state-of-the-art review on the technical aspects of processing and reporting of EBUS-TBNA specimens. A literature search was conducted using the PubMed database, and the available evidence was discussed among the authors. The evidence suggests that at least one air-dried and one alcohol-fixed slide should be prepared from each lymph node pass. The remaining material should be utilized for microbiological analysis (in saline) and cell block preparation (10% formalin or other solutions). Wherever available, rapid-onsite evaluation should be performed to assess the adequacy of the sample and guide the need for additional material. The lymph node aspirate should also be collected in Roswell Park Memorial Institute solution in cases where lymphoma is under consideration. The use of liquid-based cytology provides good quality specimens that are free from blood and air-drying artifacts and can be used wherever available. Sample adequacy and the diagnostic category should be furnished separately in the cytology report.

Abstract
Assessment of lymphadenopathy in children represents a diagnostic challenge because of the extensive differential diagnoses, including reactive and malignant conditions. Knowledge of the etiologic pattern of lymphadenopathy in a given geographical region is essential for making a confident diagnosis or for suspecting a disease. Hence, the present study was carried out to identify different etiologies of lymphadenopathy in children in our region and to assess parameters commonly associated with malignancy, with an emphasis on the role of pathology. One hundred and twenty patients aged 1 month to 18 years were included in the study. They were sorted into neoplastic and nonneoplastic (infectious and noninfectious) groups. In 56 patients, biopsy (fine needle aspiration cytology [FNAC], core needle, or excision biopsy) was essential to reach the final diagnosis. Sensitivity of FNAC in the differentiation between neoplastic and nonneoplastic lymphadenopathy was 92.3%, and specificity was 90.0%, with a diagnostic accuracy of 91.3%. We concluded that malignancy should be suspected in the following conditions: presence of abdominal or multiple symptoms; symptom duration of 1-6 months; generalized lymphadenopathy; multiple groups of lymph node (LN) involved; LN size > 2 cm; amalgamated, hard, fixed, and nontender LNs; certain abnormal complete blood count findings; blast cells in blood film; and elevated lactate dehydrogenase level. In such cases, LN biopsy is highly recommended. A final diagnosis was achieved after integrating information from history and clinical findings with the laboratory, radiological, pathological, and microbiological findings. Accordingly, an algorithm for primary diagnostic evaluation of children with lymphadenopathy is suggested.

Abstract
OBJECTIVES The field of cytopathology has been rapidly advancing in the era of molecular pathology and personalized medicine. On-site cytologic evaluation for adequacy and triaging specimens for small core biopsy or fine-needle aspiration (FNA) are often required. Cytopathologists face the challenge of how to best triage small specimens for diagnosis, molecular testing, and personalized treatment. Owing to its minimally invasive nature, FNA alone or combined with core biopsy for lymphoproliferative disorders and soft tissue tumors has gained popularity. METHODS Literature review and author's institutional experience are used for this review article. This article will focus mainly on lymphoproliferative disorders and soft tissue tumors. RESULTS Evaluation combining cytomorphology, immunohistochemistry, and/or molecular pathology is often needed to accurately diagnose and classify lymphomas and soft tissue tumors. Many molecular tests have been performed on cytologic specimens, such as tests for BRAF and RET in thyroid FNA. CONCLUSIONS Molecular pathology has been widely integrated into conventional cytopathology for diagnosing lymphoproliferative disorders and soft tissue tumors, and the diagnostic value of FNA on those tumors has increased significantly. Cytology will play a more important role in the era of personalized medicine.
