Endosonographic examination of thyroid gland among patients with nonthyroid cancers.

Objectives: There is limited endosonographic literature regarding thyroid gland pathology, which is frequently visualized during upper endoscopic ultrasound (EUS). Our objective was to assess the prevalence of benign and malignant thyroid lesions encountered during routine upper EUS within a cancer center setting.

Materials And Methods: The data were prospectively collected and retrospectively analyzed.

Primary papillary thyroid carcinoma diagnosed by using endoscopic ultrasound with fine needle aspiration.

There is paucity in the literature on the use of endoscopic ultrasound (EUS) for evaluating the thyroid gland. We report the first case of primary papillary thyroid cancer diagnosed by using EUS and fine needle aspiration (FNA). A 66-year-old man underwent EUS for the evaluation of mediastinal lymphadenopathy.
