Introduction: Thyroid cancers are malignant cell proliferations developed at the expense of the thyroid gland, and which can spread from a distance. Most cancers appear in the form of anterior cervical swelling. Ultrasound and pathological examination allow the diagnosis of certainty. In Thiès, the studies carried out on thyroid cancers essentially focus on clinico-radiological and therapeutic aspects. We propose, through this study, to describe the epidemiological aspects and the morphological characteristics of thyroid cancers at Thiès Regional Hospital Center. Methodology: This is a retrospective, descriptive and analytical study conducted over a period of 3 years and 6 months, from January 2019 to June 2022. All patients with thyroid cancer confirmed by histological examination were included. Results: The patients who met the inclusion criteria were fourteen in number (14). The average age of patients was 40, 7 +/- 19 years old with extremes of 08 years and 75 years. Our series reports an 86% majority of women against 14% of men, with a sex ratio of 0.17. The isolated thyroid nodule was the most frequent mode of revelation of papillary thyroid cancers in our series, representing 54.6% of patients. The samplings received at the laboratory were essentially total thyroidectomy specimens. The tumor size varied between 1.5 cm and 14 cm. Papillary thyroid carcinoma was the most frequent histological type, with a frequency of 78.6%, followed by gallbladder carcinoma and squamous cell carcinoma. Conclusion: Thyroid cancers affect young subjects and are discovered at a late stage in our context.
