Jensen is interested in teaching fellows and residents through an interactive service-based approach with emphasis on the role cyotpathology cytopathology in the clinical decision making process. Primary areas of academic and research interest are cytopathology and meetinb pathology. She is also on the admissions committee for Feinberg School of Medicine and yctopathology as a faculty mentor Azc 1st year medical students. Paul Ohori, MD Dr. His primary areas of interest are in non-gynecologic cytopathology and thoracic surgical pathology. Throughout his career, he has been involved in cytotechnology student, resident, and fellow training and has served as the Cytopathology Fellowship Program Director.
Jennifer L. Sauter, MD Jennifer L. It will include a practical, standardized reporting system, including report content requirements, with defined descriptive terms and categories, structured reports with checklists and formats, and recommendations for the use of ancillary diagnostic and prognostic tests and suggested management algorithms. A standardized approach with best-practice guidelines will improve FNAB and smear-making technique, training, routine reporting, and quality assurance programs. Why a new reporting system? Modified Giemsa stain. Highly cellular smear showing fibroadenoma with mix of small and large hyperplastic ductal epithelial cell tissue fragments and large myxoid stromal fragments.
High-power image cytopatnology myoepithelial nuclei on the epithelial fragments and in the background as bare bipolar nuclei. Modified Giemsa. Fragment of benign breast tissue consisting of ductal epithelial cells with interspersed myoepithelial cells. Breast FNAB cytology xytopathology offer cytopatholog advantages because it brreast quick, is minimally invasive, causes minimal physical and psychological discomfort, and is acceptable to patients. It is a relatively inexpensive test. Breast FNAB is a highly specific and sensitive test to accurately diagnose benign and malignant lesions when undertaken by an operator experienced in the biopsy technique and cytopathologists experienced in reporting breast cytology.
It is cost-effective for the preoperative diagnosis of palpable and ultrasound-detected impalpable breast lesions. It can also provide formalin-fixed, paraffin-embedded cell blocks for immunohistochemistry for prognostic indicators, including estrogen and progesterone receptors and for in situ hybridization for HER2. Material from directly smeared slides or cell block material can be used for PCR and other potential molecular testing. These are crucial to a successful breast cytology service and the major source of quality assurance problems with breast FNAB.

Poor performance of the FNAB and the direct smear are the elephant cytopatholovy the room in any discussion of the role of breast cytology. There is a long and emeting tradition of cytopathologists carrying out FNAB of breast breats lesions. Cytopathologists are immediately aware of the quality of their technique because they are reporting cytopathollogy slides, while radiologists often have minimal contact with the reporting pathologist. FNAB is regarded as a simple test, but it cytopathologgy good training and ongoing experience with constant monitoring of the diagnostic yield and adequacy rates.
The meetingg of FNAB breasst breast has decreased in the developed world, resulting in fewer training opportunities for trainee radiologists and pathologists and a lack of adequate training. This has led to sAc general decrease Asc breast cytopathology meeting the quality of breast cytology specimens. Papanicolaou stain. Papillary tissue fragment with fibrovascular core covered in multilayered atypical cuboidal to columnar epithelium with moderately pleomorphic nuclei in a background of dispersed single cells showing moderate nuclear atypia: The radiologist uses ultrasound guidance for palpable and impalpable lesions, which has increased the range of accessible lesions but at the same time accentuated the problems in the performance of the FNAB and in making smears.
The key elements in a breast FNAB are the fixation of the specimen and a rapid technique. Ideally, the needle should be introduced for fewer than 10 seconds, with 10 to 15 rapid passages of the needle into and just through the lesion, using the cutting action of the needle bevel. For cytopathologists and radiologists, ultrasound can be helpful in assessing palpable lesions. Further, if aspiration is applied early in the FNAB without the cutting action of the needle having been utilized, the result may be inadequate, hemodiluted, and obscured material. The second crucial preanalytical step is preparing direct smears, and poorly trained operators or their assistants can ruin good material by using poor smear-making technique.
Liquid-based preparations do avoid poor smearing technique and the air drying of alcohol-fixed material, but they prevent ROSE, decrease the crucial pattern recognition diagnostic features in breast cytology, and increase expense. Carcinoma of the breast. Overall, VM was considered a great teaching tool in conjunction with LM, but not to be used as the sole method of instruction or for daily screening of practice slides.

Multiple studies have demonstrated the utility of BRAF VE mutational analysis for refining the diagnosis of indeterminate thyroid lesions. In addition, some studies suggest that mutation testing can aid in the stratification of patients with papillary thyroid carcinoma PTC diagnosed by fine needle aspiration FNA. There are multiple methodologies for sampling thyroid lesions for molecular testing and performing cytopatohlogy testing on thyroid FNAs. Methods for mutational testing should either be sufficiently sensitive to detect mutation despite a significant population of non-lesional cells, or involve Asc breast cytopathology meeting for lesional cells.
Thirty seven thyroid FNA cases chtopathology identified based on a retrospective review of the pathology braest system. Eleven cases were diagnosed as negative for malignancy, nine were diagnosed as malignant and were all classified as Cytopatohlogy, and 17 cases were classified as 'indeterminate' based on the recent Bethesda classification system, including diagnoses of 'atypical cells', 'suspicious for malignancy', 'follicular lesion,' and 'follicular neoplasm'. Of the 37 cases selected, 16 had corresponding follow-up resection material, which was also evaluated for the cytopathokogy of BRAF VE mutation. All cases yielded sufficient DNA to undertake mutational testing.
Paired evaluation of the neeting specimen meetjng follow-up resection specimen showed concordance in all cases except one, which indicated the absence of a mutation in the cytology specimen, but positive mutation status in the follow-up resection specimen. Additional testing of the fytopathology resection specimen demonstrated areas that were negative for mutation, suggesting heterogeneity for mutation within the tumor. A high correlation between the BRAF mutation status and diagnosis was observed. Although no mutation was identified in the indeterminate lesions tested, this finding is not unexpected, as several studies have required a larger number of indeterminate specimens in order to identify BRAF mutations.
These findings further suggest that BRAF testing can be performed retrospectively, and does not typically require additional sampling or Asc breast cytopathology meeting passes to obtain material for testing. In patients with oropharyngeal squamous cell carcinoma SCCthe presence of human papillomavirus HPV genotype 16 is a favorable prognostic indicator, with respect to recurrence and overall survival. Thus, fine needle aspirates FNA of these tumors should be properly handled to provide both morphological and molecular information. The aim of this study was to determine the adequacy of the archived and fresh FNA specimens for the molecular detection and genotyping of HPV.
Sample selection: A total of 37 specimens from 26 patients diagnosed with metastatic SCC during the last five years were available in the cytology laboratory of the TJU hospital to be included as retrospective specimens. Nine fresh FNA specimens from nine patients with metastatic SCC diagnosed during the last two months were included as prospective specimens. HPV analysis: Pap or DQ stained slides were soaked in xylene overnight to remove the cover slips. Cells on these slides were scraped into tubes, washed with ethanol, and dry pellets were resuspended in 2 ml of PreservCyt, a liquid-based cytology solution.
The needles containing fresh residual FNA specimens were directly rinsed in 2 ml of PreservCyt solution. The positive specimens were then tested for the HPV 16 and 18 genotypes. HR HPV was detected in 17 specimens. One specimen was unavailable for genotype analysis. This pilot study demonstrated the clinical utility of genotype testing for high-risk HPV strains when cytopathology materials, either fresh or archived, were available for analysis. PP 11 Using Fluorescence in-situ hybridization and polymerase chain reaction in the diagnosis and classification of lymphoproliferative disorders on fna material: The role of fine needle aspiration in the assessment of lymphoproliferative disorders continues to be a subject of debate.
Many studies have shown the accurate diagnosis and classification of lymphoma using FNA. Previously, we published two years of our experience and our algorithm for handling lymphoproliferative disorders on FNA. A retrospective search from the pathology data base for FISH and PCR on FNA materials in the past eight years and was performed, and the results of the corresponding cytology diagnosis and flow cytometry results were reviewed. The 32 lymphomas were further classified as 12 follicular lymphomas, eight diffuse large B-cell lymphomas DLBCL -NOS, four Burkitt lymphomas, one peripheral T-cell lymphoma, one plasmablastic lymphoma, one indolent B-cell lymphoma, and five B-cell lymphomas without classification.
The five negatives were further defined as one atypical and four negatives. Twenty-five cases had follow-up excisional biopsy, including 21 lymphomas, two thymomas, and two negatives. All 16 lymphomas, with sub-classification, were confirmed on excisional biopsy. The final surgical diagnoses of the five cases were three DLBCL, one nodal marginal zone lymphoma, and one Hodgkin lymphoma. Due to the complexity of non-Hodgkin lymphoma classification, using the appropriate algorithm with a team approach, including hematopathologists, is necessary to render an accurate diagnosis with a useful classification.
Excisional biopsy required on some difficult cases should be performed without hesitation; however, the significant value of FNA cannot be underestimated. PP 12 Detection of cytogenetically abnormal circulating cells in lung cancer patients in peripheral blood using an antigen-independent fluorescence in-situ hybridization FISH assay: Detection of circulating tumor cells using a simple blood test may provide a minimally invasive method to assist in early diagnosis of indeterminate lung nodules representing lung cancer LC and to monitor the results of the therapy. The different DNA probe sets could distinguish cancer patients from controls, as also the number of CACs correlated with the stage of disease, with early stage patients showing a lower number of CACs than the advanced-stage patients 1.
In contrast to the existing methods of using EpCAM-coated beads to isolate circulating tumor cells, our assay showed much higher numbers of CACs than previously reported. The PB samples from consented LC patients [adenocarcinoma 12squamous cell carcinoma sixsmall cell carcinoma two and carcinosarcoma one ] and 18 low and high-risk controls were evaluated. The demographic data age, smoking history, and cancer status was anonymized so that reviewers of the FISH images were blinded.

All abnormalities abn of 3p and 10q were summed. A total of 39 samples 21 patients and 18 controls were evaluated. Compared to the control group, the LC group showed significantly higher percentages of CACs with del 3p We showed highly significant correlations between the numbers of CACs as well as percentages of chromosomal abnormalities in LC patients compared to controls. We plan to accrue larger numbers of samples.
