The thyroid gland is an endocrine organ located in the front of the neck, it is butterfly-shaped. It consists of two lobes connected by an isthmus. Thyroid neoplasms are the most common endocrine tumors in the human body. They are most often of epithelial origin. Of the malignant tumors, thyroid carcinoma is the most common. It is more common in women. Thyroid carcinomas can be well and poorly differentiated (mature and immature). Well-differentiated include papillary and follicular carcinomas. Among the immature thyroid carcinomas are medullary and anaplastic types. The TNM system is widely accepted, recommended for reports, the prognosis of disease, comparison of different treatments between groups of similar cancer cases, and as a treatment guide for patients with thyroid cancer. The diagnosis of thyroid cancer includes medical history, physical examination, laboratory and radiological diagnosis, cytology, pathohistology and thyroid scintigraphy. In the treatment of thyroid cancer, total thyroidectomy with anterior neck dissection is the surgical method of choice. After the procedure, postoperative scintigraphy of the whole body with radioactive iodine 131 is often performed. The undergraduate thesis deals with the pathological findings of the subjects who were diagnosed with thyroid carcinoma in the period from 2010 to 2019 at the General Hospital Dubrovnik. The computer database of pathohistological findings of the Department of Pathology and Cytology of the Dubrovnik General Hospital was used. Age, sex, histological types of thyroid cancer and their size, the spread of tumors outside the thyroid gland, lymphovascular invasion, TNM classification, and other available prognostic factors were analyzed. In 10 years, 81 patients were diagnosed with thyroid carcinoma, and 60 of them were female patients. The most common histological type of carcinoma was papillary. The highest number of diagnosed thyroid cancers was in 2010 (14 cases). In most patients, cancer did not spread beyond the thyroid gland.
