case_images: Histology from the total thyroidectomy showing the focus of the papillary thyroid carcinoma. A. Papillary thyroid thyroid carcinoma, classic variant in the background of papillary hyperplasia (hematoxylin & eosin stain, 4X magnification). B. Papillary thyroid carcinoma with nuclear enlargement and overlapping. Optically clear nuclei with thick nuclear membrane (hematoxylin & eosin stain, 40X magnification).

case_images: A 0.4 cm focus of papillary thyroid cancer was noted on the left lobe (Figure 1A, 1B).

case_images: Serial labs showed persistent hyperthyroidism due to which her levothyroxine dose was gradually lowered until she reached a nadir dose of levothyroxine 50 mcg daily at one year after her near-total thyroidectomy (Figure 2).

case_images: A neck ultrasound was obtained, which confirmed this finding (Figure 3). She displayed a gradual increase in her levothyroxine dosage requirement over the next year along with a slow decline in her thyroglobulin level (Figure 3).
