Concomitant tonsillar cyst and papilloma in larynx: A case report

RATIONALE: Laryngeal cysts are rare lesions that may occur at any mucosa-lined location within the larynx. Papillomas are also benign lesions of the larynx. PATIENT CONCERNS: We report a 34 year-old-patient with a laryngeal cyst incidentally found during screening endoscopy and presenting as a soft tissue mass on a computerized tomography scan. A papilloma concomitant with the cyst was detected intraoperatively. DIAGNOSES: Concomitant tonsillar cyst and papilloma of the larynx. INTERVENTIONS: The lesion was completely resected with a bipolar radiofrequency plasma ablation (RFA) device. OUTCOMES: Pathologic examination showed a tonsillar cyst and papilloma in the larynx. Six months later, there has been no evidence of recurrence. LESSONS: To our knowledge, this is the first report of a concomitant tonsillar cyst and a papilloma in the larynx. Asymptomatic laryngeal cysts can be detected endoscopically. RFA is safe and effective for endoscopic management.
