^aThis patient harbored multifocal thyroid carcinomas, including an encapsulated thyroid-confined 7.2 cm Hürthle cell carcinoma with extensive vascular and capsular invasion, an encapsulated Hürthle cell carcinoma with two foci of capsular invasion, and two PTC (one of which had microscopic extrathyroidal extension into the perithyroidal adipose tissue). The histological classification of the lymph node metastases was papillary carcinoma, classical variant.

LN, lymph node; M, male; F, female; FVPTC, follicular variant papillary thyroid carcinoma; PMC, papillary microcarcinoma; PDTC, poorly differentiated carcinoma according to MSKCC criteria; NA, not applicable; FU, follow-up; DM, distant metastasis.
