title: Occult papillary carcinoma of the thyroid presenting as an intratracheal tumour.
abstract: A case of occult papillary carcinoma of the thyroid presenting as an intratracheal tumor in a 64-year-old woman is reported. No lymph node metastases were observed. The patient had an 11-year history of hoarseness, dyspnea and productive cough, and was found at bronchoscopy to have a large intratracheal tumor occupying half of the lumen. It was histologically a papillary carcinoma with immunoreactivity of thyroglobulin. No primary tumor was found in the thyroid gland. By reviewing the English literature, no similar case was encountered.
