Plasmacytoid morphology of poorly differentiated thyroid carcinoma: Diagnostic approach with a brief review of the literature

Abstract

Poorly differentiated thyroid carcinoma (PDTC) are unusual tumours which are rarely diagnosed with accuracy in cytology. Plasmacytoid morphology of the tumour cells can cause diagnostic difficulty as it mimics many other primary thyroid tumours: however it can be accurately diagnosed if certain fine morphological clues are identified while reporting.
