	<span style="line-height:1.5;">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</span><span style="line-height:1.5;"> thyroid cancer. Treatment modalities should address the
most aggressive tumor, while being tailored to clinical picture, tumor histology,
and patient preferences.</span>
