Background: Iodine deficiency (ID) still affects over two billion people worldwide (266 million school aged children). Pathology patterns in ID include: increase in thyroid cancer, higher percentages of follicular and anaplastic cancers and inversion of the papillary/follicular thyroid cancer frequency ratio. China succeeded in eliminating ID through legislation introduced in 1987 aimed at availability of iodized salt countrywide and South Africa through legislation introduced in 1995. Read More

Oncocytic variant of medullary thyroid carcinoma is rare form of thyroid carcinoma that is easily misdiagnosed on fine needle aspiration specimens due to it is low incidence and cytomorphologic overlap with other more common Hurtle cell lesions. A correct initial diagnosis by fine needle aspiration is imperative as the clinical treatment for medullary carcinoma differs significantly from the mimickers. We present a case of this rare variant tumor that on initial fine needle aspiration was described as a Hurthle cell lesion and was subsequently correctly classified on the resection specimen.

Oncocytic (Hürthle cell) and follicular neoplasms are related thyroid tumors with distinct molecular profiles. Diagnostic criteria separating adenomas and carcinomas for these two types of neoplasms are similar, but there may be some differences in the biological behavior of Hürthle cell and follicular carcinomas. Recent studies have shown that noncoding RNAs may have diagnostic and prognostic utility in separating benign and malignant Hürthle cell and follicular neoplasms. Read More

The diagnosis of follicular-patterned carcinomas, including follicular thyroid carcinoma, oncocytic (Hürthle cell) carcinoma, and the encapsulated follicular variant of papillary thyroid carcinoma, requires evidence of capsular and/or vascular invasion. With minimally invasive carcinomas classified often within less than a millimeter of tissue segregating them from adenomas and non-invasive follicular thyroid neoplasms with papillary-like nuclear features, opinions vary internationally over how much of the capsule to submit in order to deem it well enough represented, considering that even if grossly entirely submitted in microcassettes, without leveling through each tissue block, the capsule is truly never entirely examined microscopically. Here, we retrospectively examine submission practices and outcomes at a single, high-volume institution over a 25-year period. Read More
