Abstract

Introduction: Ectopic thyroid is a rare event, with an incidence of 1 in 300,000 cases. The probability of a carcinoma appearing in this tissue is less than 1%. It may be extremely difficult to distinguish a primary neoplasm involving the ectopic thyroid from a metastatic cervical lymph node. Case report: We report a case of papillary carcinoma in lateral cervical ectopic thyroid region. It was initially diagnosed as a thyroid carcinoma with lateral cervical metastasis. Comments: The diagnosis of papillary carcinoma in lateral cervical ectopic thyroid can be challenging, and immunohistochemistry can be a useful tool.
