Primary Papillary Thyroid Carcinoma Originating in Branchial Cleft Cyst Case Report and Review of Literature

Highlights

Branchial cleft cysts are considered the most common masses in the lateral neck and ectopic thyroid tissue within a branchial cleft cyst is an unusual phenomenon
We are reporting a case of papillary carcinoma originating in a branchial cleft cyst (BCC) in an adult patient without evidence of papillary carcinoma in the thyroid gland
Whether thyroid carcinoma is originating primarily in BCC or associated with primary thyroid carcinoma or paired with another lateral neck anomaly, all will be discussed in this report as well as a review of the literature

Summary

Introduction

Branchial cleft cysts are considered the most common masses in the lateral neck and ectopic thyroid tissue within a branchial cleft cyst is an unusual phenomenon. The most common location of ectopic tissue is at the base of the tongue, various cervical or remote sites have been reported. Based on this concept, an ectopic thyroid tissue can be identified on a pre-existing benign branchial neck cleft cyst [1,2,3,4,5]. An ectopic thyroid tissue can be identified on a pre-existing benign branchial neck cleft cyst [1,2,3,4,5] This is a 41-year-old female presented with left supraclavicular cervical lymphadenopathy. Immunohistochemical stain shows the tumor cells are positive for TTF-1, CK19, and P63 (Figure.3)
