case_images: Microscopic examination showed normal thyroid and an encapsulated tumor in the parathyroid gland (Figure 1a (Fig. 1)). Multiple fibrous bands extended from the thickened capsule dividing the neoplasm into lobules with cells arranged in sheets and trabeculae (Figure 1b (Fig. 1)).
case_images: a: Photomicrograph shows an encapsulated parathyroid tumor (arrow) along with normal thyroid and parathyroid tissue (H&E 100X). b: Photomicrograph shows fibrous bands dividing the neoplasm into lobules with cells arranged in sheets and trabeculae (H&E 100X).
