Transoral robotic surgery for oncocytic ductal cyst of hypopharynx: a lesion with a high probability of recurrence.

Hypopharyngeal cysts are very uncommon pathology. They are presented in adult people over 60 years. Although oncocytic cysts are benign tumors, an incomplete resection causes recurrence.

Bilateral vallecular cyst: transoral robotic resection.

Vallecular cyst is more frequent in neonatal life, but could be present in adults. Frequently it is asymptomatic although some people has foreign body sensation upon swallowing and obstructive problems to sleep. The best treatment for these cases is complete resection, as recurrence is usual with any cyst remnant wall causing re-accumulation.

HPV Involvement in Head and Neck Cancers: Comprehensive Assessment of Biomarkers in 3680 Patients.

Background: We conducted a large international study to estimate fractions of head and neck cancers (HNCs) attributable to human papillomavirus (HPV-AFs) using six HPV-related biomarkers of viral detection, transcription, and cellular transformation.

Methods: Formalin-fixed, paraffin-embedded cancer tissues of the oral cavity (OC), pharynx, and larynx were collected from pathology archives in 29 countries. All samples were subject to histopathological evaluation, DNA quality control, and HPV-DNA detection.
