All of the following are histopathological findings of papillary carcinoma, except

Pathology Papillary projections Psammoma bodies (concentric calcifications) Pale empty (orphan annie) nuclei → FINELY DISPERSED CHROMATIN IMPARTS AN EMPTY APPEARANCE Intranuclear grooves and nuclear characteristics are diagnostic of papillary carcinoma Multifocality is common in papillary carcinoma TSH levels are high; tumors are TSH dependent, hence follow-up with TSH. Key Concept: Multifocality is common (up to 85% of cases) on microscopic examination. Multifocality is associated with an increased risk of cervical nodal metastases, rarely invade adjacent structures such as the trachea, esophagus, and RLNs. RLN implies lymph nodes.
