DOIAbstract
Background: Palpable thyroid nodules can be found in 4%–7% of the adult population; however, <5% of thyroid nodules are malignant. Immunohistochemical markers, such as CD56, can be used to make a differential diagnosis between benign and malignant lesions. To increase the accuracy of the diagnosis and distinguish the malignant aspirates from the benign ones, chose to evaluate CD56, which is normally found in benign thyroid tissue. Methods: A total of 53 fine-needle aspirate samples from patients diagnosed with suspected papillary thyroid carcinoma (PTC) were included prospectively. These aspirates were immunocytochemically stained for CD56. Results: In histopathological examination, the fine-needle aspiration cytopathology specimens suspici...
