Occult Papillary Thyroid Carcinoma Presenting as a Cystic Neck Mass / 대한내분비외과학회지

ABSTRACT

The majority of cystic masses in the lateral neck are benign entities, and these entities include branchial cyst. Occult papillary thyroid carcinoma can occasionally present with regional lymph node metastasis. However, cystic metastasis from occult papillary thyroid carcinoma is a very rare condition. We present here a case of a cystic neck mass as the sole initial clinical manifestation of metastatic occult papillary thyroid carcionoma.
