title: Oncocytic variant of poorly differentiated thyroid carcinoma: "Is diagnosis possible by fine-needle aspiration?"
abstract: Poorly differentiated thyroid carcinoma (PDTC) is a very rare entity, and the diagnosis can be made on histopathology specimens. However, recognition of characteristic features of PDTC is significant on fine-needle aspirations (FNAs) to differentiate this entity from well-differentiated and anaplastic thyroid carcinomas. Here, we present an FNA case concordant with "oncocytic variant of PDTC" and discuss whether definitive diagnosis can be given on FNAs to assess the prognosis in clinically inoperable patients.
