case_images: Intraoperative findings included multiple non-obstructive papillomatoid lesions of the supraglottis, vocal cords and subglottis, as well as an atypical circumferential lesion extending from subglottis to 3 cm from the carina (Figure 1). Restaging PET 10 weeks following completion of chemoradiotherapy demonstrated marked reduction of metabolic activity in the primary site and no new nodal disease or distant metastatic disease (Figure 1). SCC (Figure 1). Subsequent to this, he required 3-6-weekly balloon dilation for worsening stridor associated with his airway stenosis.
