Thyroid Lesions

More than 50% of the world’s population has at least a thyroid nodule. Detail clinical examination and radiology may help in diagnosing thyroid lesions but the management depends upon the cytopathological diagnosis. Optimum use of fine needle aspiration cytology (FNAC) and better understanding of cytomorphological characteristic of thyroid lesions by using Bethesda system, triaging of patients who are to be treated medically or surgically is more accurate. The objective of this present study is cytopathological evaluation of thyroid lesions based on Bethesda System in patients attending Birat Medical College and Teaching Hospital. The objective was also to correlate the cytological findings with histopathological findings where ever possible. A total of 104 patients with thyroid lesions underwent fine needle aspiration cytology in a period of a year (September 1, 2019 to August 31, 2020). Cytological features were evaluated and classified according to the Bethesda system. Histopathological features were evaluated and correlated wherever available. Among 104 patients with thyroid lesions 93 were female and 11 were male. Four cases turned out to be non diagnostic, 85 benign, three Atypia of undetermined significance, three Suspicious for follicular neoplasm and eight Suspicious of malignancy and one Malignant according to Bethesda system. Histopathology specimen was received in 31 patients out of whom 20 (64.5%) patients were reported as colloid nodule, two follicular adenoma, one Hurthle cell adenoma, six papillary carcinoma and two follicular carcinoma. Medullary carcinoma and anaplastic carcinoma were not seen in the patients evaluated. Specificity and sensitivity of fine needle aspiration cytology was 94.7% and 88.9% respectively. Thus reporting thyroid lesions FNAC with Bethesda system allow a more specific cytological diagnosis.

Thyroid Lesions

Background: Fine Needle Aspiration Cytology (FNAC) of thyroid gland is the most common preoperative investigation for diagnosis of thyroid lesions. Though various tests like thyroid profile, ultrasonography and radionuclide scan are available, they are used as adjuvant diagnostic modalities. FNAC is simple, easy to perform, non-invasive and cost-effective procedure. Primary aim is to study the spectrum of various thyroid lesions on FNAC. Also, the study is aimed to categorise the thyroid lesions according to the Bethesda system for Reporting Thyroid Cytopathology (2017).Methods: This is a retrospective observational study carried out in the pathology department at tertiary care academic institute for a period of three years. FNAC was done in a patient with thyroid swelling by non-aspiration technique. Slides were prepared, fixed in 95% ethyl alcohol and processed with routine stains.Results: Out of 210 cases, 150 cases (71.42%) were benign lesions, 15 cases (7.14%) were Follicular neoplasm/Suspicious for follicular neoplasm, 14(6.66%) cases were reported as Atypia of undetermined significance, 13 cases (6.19%) were Unsatisfactory/Nondiagnostic, 11 cases (5.2%) were malignant and 7 cases (3.3%) were suspicious for malignancy.Conclusions: FNAC is the most effective tool for the diagnosis of thyroid lesions. The Bethesda system is used to categorise the thyroid lesions and helps in better communication between clinicians and pathologists for the best surgical and medical management. The number of benign cases were higher and the number of cases in the category of suspicious for malignancy were lower with female preponderance.

Thyroid Lesions

Background: It has been reported that African-Americans (AA) have a higher prevalence of overall malignancy compared to Caucasians, in the United States, yet the incidence of thyroid malignancy is half. The aim of this study is to assess the rate of malignant versus benign thyroid disease in AA from an urban-based hospital with an academic setting. Our study analyzed the AA population with respect to fine needle aspiration (FNA) of thyroid lesions, in correlation with final surgical pathology. This is the first study of its kind to our knowledge. Design: We retrospectively reviewed thyroid FNA cytology between January 2005 and February 2011. Consecutive FNA specimens with corresponding follow-up surgical pathology were included. The patients were categorized as African- American (AA) and Non-African-American (NAA), which included Caucasians (C), Hispanics (H), and Others (O). The FNA results were classified using the latest edition of The Bethesda System for Reporting Thyroid Cytopathology (TBS-Thy) and the follow-up surgical pathology was used for the final categorization. Results: We studied 258 cases: 144 AA (56%) and 114 NAA [43 C (17%), 3 H (1%), and 68 O (28%)]. The average age for AA was 51 years (range 20 – 88) and for NAA was 53 years (range 25 – 86). There were more females than males in the AA versus the NAA group (85 vs. 75%). The incidence of thyroid lesions in the FNA specimens was similar between these two populations. The distribution of benign versus malignant diagnosis on follow-up surgical pathology was examined across TBS-Thy class. Conclusion: Our data suggest that distribution of benign versus malignant lesions in the thyroid FNA of AA versus NAA, with follow-up surgical pathology, is comparable for TBS-Thy classes, non-diagnostic (I), benign (II), suspicious for malignancy (V), and malignant (VI) in AA versus NAA.
