Cytomorphological study of thyroid carcinoma.

The most common neoplasm of the endocrine system is found in the thyroid gland with a significant increase in recent decades largely due to modern diagnostic methods. Thyroid tumors generally have a favorable evolution, but there are also aggressive variants with a poor prognosis. In these aggressive tumors, the most reliable method of detecting and making a differential diagnosis is represented by ultrasound-guided fine-needle cytopuncture, confirmed by histopathological examination. Although fine-needle aspiration puncture and cytological examination are considered to have a high sensitivity and specificity, diagnostic certainty is established later only by histopathological examination. Fine-needle aspiration cytopuncture of the thyroid gland correlated with histopathological examination has played a crucial role in recognizing and identifying variants of papillary carcinoma known to have aggressive biological behavior, especially in cases of poorly differentiated carcinoma. Recognition of aggressive variants of papillary carcinoma is of major importance in the prognosis and clinical management of patients. The aim of this study was to present the correlations found in a series of thyroid tumors from patients treated in surgery and oncology departments, as well as tumors accidentally detected during autopsies in the department of forensics. All the cases selected in the study benefited from a complex histopathological diagnosis adapted to each case in order to ensure maximum efficiency.
