Saccular cyst caused by recurrent respiratory papillomatosis

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.

Unilateral combined laryngocoele with recurrent respiratory papillomatosis: case report

Objective:

We report a case of unilateral combined laryngocoele occurring in conjunction with recurrent respiratory papillomatosis.

Methods:

Case report and review of the literature concerning the physiology underlying laryngocoele formation.

Results:

A laryngocoele is an abnormal, air-filled dilation of the laryngeal saccule which communicates with the laryngeal lumen. We report a case of a 53-year-old man with a unilateral combined laryngocoele occurring in conjunction with recurrent respiratory papillomatosis. Microlaryngoscopy demonstrated a papilloma obstructing the laryngeal saccule. Removal of papillomata via laser excision and marsupialisation of the left laryngocoele improved the patient's vocal symptoms. There was no recurrence of papillomata or the laryngocoele.

Conclusion:

While many laryngocoeles can be explained by altered laryngeal physiology, the papilloma described in this case acted as an anatomical obstruction that trapped air within the saccule, creating an environment conducive to laryngocoele formation.
