The Bethesda system (TBS) is a system for reporting cervical or vaginal cytologic diagnoses, used for reporting Pap smear results. the bethesda system for reporting thyroid cytology (tbsrtc) TBSRTC was proposed in 2007 to provide a framework and address the inconsistencies and limitations of the available diagnostic terminology at that time for thyroid FNA cytology specimens. Papillary thyroid carcinoma, follicular variant. In the years following the publication of this reporting system, multiple studies confirmed the utility of the Bethesda terminology [17–21].Few institutional modifications and suggestions were also reported [22–28].However, currently, this system seems to be the most widely accepted terminology for reporting thyroid cytology in the literature. The system is widely accepted in the United States and globally. See our Privacy Policy and User Agreement for details. Each category conveys a risk of malignancy and recommended next steps, though it is unclear if each category also predicts the type and extent of malignancy. Moderator Dr G K Parvathidevi .

Papillary thyroid carcinoma, macrofollicular variant. 1,2 To report benign thyroid cytopathology results, the term "Benign" is preferred over other terms such as "Negative for malignancy" and "Nonneoplastic." In such cases there can be abundant thin colloid and relatively few sheets of cells. J O S E F A G .

Fine-needle aspiration cytology (FNAC) has become a well-established modality in the diagnosis, staging and follow-up of thyroid nodules. importance of thyroid cytology in the diagnosis of thyroid nodules is highlighted in several guidelines.5 Rising investigation of thyroid problems and the common finding of multiple thyroid nodules on radiological investigation6 have increased the demand on the use of thyroid cytology to help diagnose and triage patients. Bethesda categories III and IV encompass varying risks of malignancy. Although the original six diagnostic categories have been retained in their original form, important changes have been incorporated, including notable changes related to … Highlights of the 2017 Bethesda System for Thyroid Cytopathology. Cytopathol. These changes were patchy, however, and other follicular cells looked entirely benign (ThinPrep, Papanicolaou stain). 1. The difference lies in the nuclear features, which are better appreciated at high magnification (smear, Diff-Quik stain). Papillary thyroid carcinoma, cystic variant. There is a standard way of describing thyroid cytopathology results. In the absence of immuno- phenotyping studies that demonstrate clonality, the findings are suspicious but not conclusive for malignant lymphoma (air-dried smear, Diff-Quik stain). The RCPA QA survey showed that thyroid FNAs constitute between 0-62% of the total workload of cytology laboratories. Papillary thyroid carcinoma, macrofollicular variant. Figure 8.17.

There is a mix of flat sheets and rounded, papillary-like fragments without fibrovascular cores (smear, Papanicolaou stain). Thyroid Cytopathology, 2017 Laila Khazai 11/4/17 . Papillary thyroid carcinoma, columnar cell variant of PTC. • To address terminology and other issues related to thyroid FNA, the National Cancer Institute (NCI) hosted the “NCI Thyroid Fine Needle Aspiration State of the Science Conference” on October 22 and 23, 2007, in Bethesda, and gave the format for reporting thyroid cytology. Nondiagnostic. Bethesda (2009) This is formally known as the "The Bethesda System for Reporting Thyroid Cytopathology"; it is based on the NCI classification of 2008: The cells appear slightly degenerated, making it is difficult to discern their features with certainty (air-dried smear, Diff-Quik stain). Criteria for Adequacy A thyroid FNA sample is considered adequate for evaluation if it contains a minimum of six groups of well-visualized (i.e., well-stained, undistorted, and unobstructed) follicular cells, with at least ten cells per group, preferably on a single slide.
