BACKGROUND
Hashimoto’s Thyroiditis is a leading cause of hypothyroidism results due to immune mediated destruction of follicles and is characterised by infiltration of lymphoid cells. The aim of the present study is to categorise cytomorphology in to various grades and understand the spectrum of lesion and its complications.
MATERIALS AND METHODS
Fine needle aspiration cytology was done on patients with diffuse and nodular enlargement of thyroid in the Department of Pathology, Osmania Medical College over a period of one and half year from January 2015 to June 2016. Smears were made and stained by pap staining and H & E and diagnosis is based on characteristic cytomorphology of thyroid lesion.
RESULTS
A total number of 363 cases were received in the Department of Pathology of which 246 cases presented with diffuse enlargement and rest were nodular with varied cytological features. A total number of 177 cases of Hashimoto’s thyroiditis were diagnosed of which 171 cases presented with diffuse enlargement and 6 cases as nodular are the subjects of present study.
CONCLUSION
Fine needle aspiration is a simple and reliable diagnostic procedure in the evaluation of Hashimoto’s thyroiditis. The present study emphasises that cytomorphologic grading of HT is useful in deciding the line of treatment, its followup and complications.
