Abstract:

Metastasis to the thyroid is extremely rare. In recent years, there is an increase in metastasis to the thyroid. This may be related with common use of the fine-needle aspiration biopsy. Synchronized occurrence of the oncocytic variant of papillary carcinoma of the thyroid and metastasis into thyroid, especially of esophageal origin, is very rarely seen. We present a rare case of a 56-year-old female in whom a primary esophageal squamous cell carcinoma gave rise to a metastatic palpable mass in the left lobe of thyroid gland and oncocytic variant of papillary carcinoma of the thyroid in the right lobe of thyroid gland.
