ABSTRACT

Carcinoma showing thymus-like differentiation (CASTLE) is rare carcinoma of the thyroid or surrounding soft tissue of the neck with a histologically resemble to thymic epithelial tumors. It originates from ectopic thymus or branchial pouch remnants. Treatment is surgical excision and prognosis is good. Differential diagnosis is squamous cell carcinoma of thyroid and lymphoepithelioma of thymus. We report a case of CASTLE combined with papillary carcinoma of the thyroid that we treated by surgery, radio-iodine therapy and radiation therapy. The initial FNA showed that the smear was consistent with papillary carcinoma of the thyroid. (J Clinical Otolaryngol 2015;26:307-311)
