Abstract
Papillary thyroid carcinomas can be retrospectively diagnosed in patients, who are having metastatic disease with an occult primary lesion. A sixty-year-old female patient was investigated for haemoptysis and was found to have a tracheal lesion. Biopsy revealed a papillary carcinoma of the thyroid. Patient underwent total thyroidectomy with excision of the tracheal lesion and was followed up by adjuvant external beam radiotherapy (EBRT) and radioactive iodine (RAI) treatment. The detailed history, examination and investigations of neck and upper aerodigestive tract (ADT) are important for correct diagnosis of papillary thyroid microcarcinoma.
Highlights
Papillary thyroid carcinoma (PTC) is one variety of well differentiated malignant epithelial neoplasm
By definition papillary thyroid microcarcinoma are less than 1 cm in diameter
It might be a finding serendipitously detected on thyroid gland imaging incidentally or from thyroid glands which were removed for other pathology
Summary
Papillary thyroid carcinoma (PTC) is one variety of well differentiated malignant epithelial neoplasm. Can be found retrospectively in patients who are presenting with metastatic disease from an initially unsuspected small primary lesion (cryptic/ occult /covert carcinoma)[1]. A sixty years old female patient had presented with haemoptysis. Mucosal tumour compatible with a papillary carcinoma of the thyroid. Immunohistochemistry staining revealed features that are consistent with a papillary carcinoma of the thyroid.
