Abstract

Occult papillary adenocarcinoma of the thyroid is known to be indolent, slow metastatic, and has a good prognosis. Occult thyroid carcinoma presenting as a blood-borne metastasis without obvious cervical lymph node involvement is extremely rare. A 65-year-old male patient was visited for hoarseness, dysphagia, and shortness of breath. Bronchoscopy with biopsy revealed a papillary carcinoma of thyroid by immunohistochemical staining. Head & neck CT revealed that involving both the upper esophagus and the posterior tracheal wall, extending into the mediastinum along the upper thoracic spine at $T_1-T_2$. We have experienced a rare case of occult papillary carcinoma which invaded the trachea, esophagus and fascia of thoracic spine. Treatment was initiated with radioactive iodine and external bean therapy.
