Thyroid Neoplasms: Nodules, Adenomas, and Carcinomas

This topic addresses the clinical concern of thyroid nodules and their pathological nature. Zambian university students in surgery and pathology will learn that the overwhelming majority of solitary thyroid nodules are benign, including follicular adenomas or non-neoplastic conditions like nodular hyperplasia. When neoplastic, over 90% are benign adenomas. Carcinomas of the thyroid are uncommon, accounting for well under 1% of solitary nodules. This topic emphasizes the importance of a systematic diagnostic approach (e.g., fine-needle aspiration) to differentiate benign from malignant lesions. Understanding the relative probabilities and the need for histopathological evaluation is fundamental for managing patients with thyroid nodules, a common clinical finding. This knowledge is essential for examinations in pathology and surgery and for evidence-based practice in Zambian healthcare settings.
