ABSTRACT

A collision tumor involving a tracheal sarcomatoid carcinoma and a papillary thyroid carcinoma has never been reported in the literature. A 78-year-old female presented with a large neck mass and hoarseness. A fine needle aspiration demonstrated papillary thyroid carcinoma. Imaging revealed a right thyroid mass invading into the tracheal lumen with bulky ipsilateral lymphadenopathy. The patient underwent a total thyroidectomy, tracheal resection, and central and right neck dissections. Pathology demonstrated a tracheal sarcomatoid carcinoma invading the right thyroid, which had multifocal papillary thyroid carcinoma with central and lateral neck metastases. The patient subsequently received adjuvant chemoradiotherapy and radioactive iodine. We present a case of a tracheal sarcomatoid carcinoma colliding with a papillary thyroid cancer. Treatment modalities should address the most aggressive tumor, while being tailored to clinical picture, tumor histology, and patient preferences.
