Oncocytic tumor cells with a background of reactive lymphoid stroma; often occur in the setting of chronic lymphocytic thyroiditis
Match the morphological (Histology and cytology) appearances with the subtype of papillary thyroid carcinoma
Diffuse involvement of at least one thyroid lobe, in association with fibrosis, frequent psammoma bodies, squamous metaplasia and frequent lymphatic invasion.
Tumor with solid / insular growth pattern
Tumor cells have high nuclear to cytoplasmic ratio with nuclei protruding away from the stalk into the lumen; often with prominent nucleoli
Defined as a cell height at least 2 – 3 times of cell width with distinct cell border and eosinophilic cytoplasm
Cribriform architecture and squamous morules; cytologically, tumor cells usually have columnar / cigar shaped nuclei, sometimes with prominent supra / sub nuclear vacuoles.
Cigar shaped nuclei with nuclear pseudostratification
