A 47-year-old woman presented with swelling on the front of her neck. Ultrasound of the thyroid revealed a 3.0 cm partially cystic, hyperechogenic nodule in the left lobe. The residual thyroid parenchyma was hypoechoic and heterogenous. Fine needle aspiration (FNA) cytology of the nodule was consistent with a papillary thyroid carcinoma, oncocytic variant. This tumour is not well recognized and we discuss how it may be distinguished from other oncocytic thyroid lesions. Materials and methodsUltrasound-guided FNA was carried out using a 27-G needle attached to a 10-ml syringe. The smears were air-dried and stained with May-Grü nwald-Giemsa (MGG) or fixed in 95% alcohol and stained by Haematoxylin and Eosin (H&E). The patient underwent total thyroidectomy and lymph node dissection. The surgical specimen was fixed in 10% formalin and embedded in paraffin. Histological sections were stained with H&E.
