Specimen Procedure: Total thyroidectomy.
Tumor Site: Right lobe (within the 2 cm cystic nodule).
Histologic Type: Papillary thyroid carcinoma, follicular variant.
Tumor Size: 2 cm (greatest dimension).
Tumor Focality: Unifocal carcinoma (arising within a background of multinodular disease).
Capsular Invasion (Thyroid Capsule): Absent; capsular integrity intact.
Extrathyroidal Extension (ETE): Absent (tumor confined to the thyroid).
Margins: Uninvolved by carcinoma (resection margins negative).
Lymphovascular Invasion: Not identified.
Regional Lymph Nodes: No lymph nodes submitted or identified.
Pathologic Stage Classification (pTNM, AJCC 8th Edition).
Primary Tumor (pT): pT1b.
Regional Lymph Nodes (pN): pNX (regional lymph nodes cannot be assessed).
Additional Pathologic Findings: Nodular adenomatous hyperplasia (multinodular goiter) involving both the right and left lobes.
Hyperplastic adenomatous nodules TIRADS II.
Received a total thyroidectomy specimen consisting of two lobes and an isthmus. The thyroid capsule was intact. The right lobe measured 7 x 4 x 3 cm. Sectioning the right lobe revealed multiple grey nodules, with the largest measuring 3.5 x 3 x 2.7 cm. One nodule in the right lobe was cystic, measured 2 cm, and was filled with bloody fluid.
The left lobe measured 6.5 x 3.5 x 3 cm. Sectioning the left lobe revealed multiple grey nodules, with the largest measuring 2.5 x 2 cm. The isthmus measured 1.5 cm.
