Thyroid cytology ppt

What are the diagnostic pitfalls in thyroid cytology?
Errors tend to occur in thyroid pathology due to a number of relatively well-known diagnostic pitfalls.
Strategies to reduce diagnostic errors include careful attention to known pitfalls and the clinical history.
Previous fine-needle aspiration or core biopsy may produce artefacts that can mimic capsular invasion..
What are the grades of thyroid cytology?
TBSRTC 2023 recommends the following as the 6 reporting category names: (i) nondiagnostic; (ii) benign; (iii) atypia of undetermined significance (AUS); (iv) follicular neoplasm; (v) suspicious for malignancy (SFM); and (vi) malignant (Table 1)..
What is a cytology test for thyroid?
Fine-needle aspiration cytology (FNAC) of thyroid is the initial screening test for thyroid nodules.
The Bethesda system classifies thyroid FNAC into six categories.
Each category is linked to a malignancy risk and has a recommended clinical management..
What is flus in thyroid cytology?
Atypia of undetermined significance/follicular lesions of undetermined significance (AUS/FLUS) refers to an intermediate histologic category of thyroid nodules in The Bethesda System for Reporting Thyroid Cytopathology..
What is thyroid FNA cytology classification?
The most important is the assignment of a single name for each of the 6 diagnostic categories: (i) nondiagnostic; (ii) benign; (iii) atypia of undetermined significance; (iv) follicular neoplasm; (v) suspicious for malignancy; and (vi) malignant..
Errors tend to occur in thyroid pathology due to a number of relatively well-known diagnostic pitfalls.
Strategies to reduce diagnostic errors include careful attention to known pitfalls and the clinical history.
Previous fine-needle aspiration or core biopsy may produce artefacts that can mimic capsular invasion.
The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) is a significant step to standardize the reporting of thyroid fine needle aspiration (FNA).
It has high predictive value, reproducibility, and improved clinical significance.

What does thyroid cytology look like?

Thyroid Cytology Must see at least 6 groups of well-visualized follicular epithelial cells, each consisting of at least 10 cells. nice big, flat (“monolayered”) sheets, with evenly nuclei with uniformly granular chromatin.
Histologically represent nodular goiter, adenomatoid nodules, and colloid nodules.

What is the pathophysiology of a thyroid nodule?

The pathophysiology of a thyroid nodule will vary depending on the lesion.
Several disorders may cause thyroid nodules.
The most common type is benign macrofollicular nodules, representing either monoclonal adenomas or colloid nodules in multinodular goiter.

What is Thyroid Cytopathology?

Thyroid cytopathology is a large part of cytopathology.
This article deals only with thyroid cytopathology.
An introduction to cytopathology is in the cytopathology article.
Head and neck cytopathology is dealt with in the Head and neck cytopathology article.
Spongiform configuration.

Which cytopathology tests are used to diagnose thyroid nodules?

Literature review current through:

Aug 2023

This topic last updated:Mar 16, 2022.
Fine-needle aspiration (FNA) biopsy and fine-needle capillary (FNC) sampling are the two most widely used diagnostic techniques for assessing the cytopathology of thyroid nodules to identify those patients who have nodules that should be excised.
