History: An 82 year old male presented with complaints of progressive dysphagia and hoarseness for a few weeks. The patient was noted to be status post partial glossectomy with bilateral neck dissection and radiation therapy for a base of tongue squamous cell carcinoma. PET/ CT scan revealed multiple lesions in the right subglottis and trachea. An endobronchial ultrasound guided FNA biopsy of the tracheal lesion was performed. Representative images are provided: DQ stain (Images 1 & 2). Pap stain (Image 3), Cell block, H&E stain (Image 4), and Immunostain of p16 and HPV ISH (image 5).
