Laryngeal myxoma: a case report and review of the literature

Laryngeal Myxoma: A rare localization

INTRODUCTION

Myxomas are benign mesenchymal neoplasms which arise mainly in the heart. The laryngeal localization is very rare. We aim to describe the clinical, histological and therapeutic features of this condition.

CASE REPORT

We report two cases of laryngeal myxomas occurred in male and female patients, presenting with a history of prolonged hoarseness. Laryngoscopy revealed a polypoid mass on the true vocal folds. The lesions were excised with cold instruments. One patient presented a recurrence 4 years after the first surgery.

CONCLUSIONS

Laryngeal myxoma should be considered in case of a benign looking vocal fold lesion, especially a vocal cord polyp. Histologic exam is the only tool to confirm the diagnosis. It is treated by surgical resection. In the literature, recurrence is rare in laryngeal site, but patients need to be kept on close follow-up.

Laryngeal myxoma: A case report

BACKGROUND

Myxomas are benign tumors of mesenchymal origin that rarely occur in the larynx.

CASE SUMMARY

We report a case of a laryngeal myxoma that presented as a right vocal cord mass in a 54-year-old man.

CONCLUSION

Laryngeal myxoma is a rare benign tumor in the larynx. It is difficult to distinguish glottis myxoma from vocal cord polyps on laryngoscopy. We recommend that otolaryngologists acquire a better understanding of this disease. If a laryngeal myxoma is suspected, dynamic laryngoscopy, acoustic voice analysis, and pathological biopsy should be performed.

Cellular Myxoma of the Vocal Cord: A Case Report and Review of the Literature

Myxomas are rare in the vocal cords. A 69-year-old man was admitted with one-year history of progressive dysphonia. Laryngoscopy revealed a polypoid mass on the right vocal cord. The diagnosis was cellular myxoma. A review of the literature including the present case revealed eleven reported cases of myxoma. Ten cases were classic myxoma. To the best of our knowledge, cellular myxoma has not been previously reported in the vocal cord. Hypercellularity does not affect the behavior of cellular myxoma. However, its recognition is important to prevent confusion with the group of low-grade myxoid sarcomas. Cellular myxoma should be considered in the differential diagnosis of any vocal cord mass.

Head and Neck Myxoma Presenting as Isolated Laryngeal Polyp

Myxoma is a benign tumour with a propensity for local infiltration and recurrence. Laryngeal myxoma presents as a submucosal polyp. Being an uncommon tumour and mimicking vocal cord polyp, only anecdotal evidence is available in the literature. The literature was reviewed from 1986 onwards using the keywords “myxoma” and “larynx.” The databases used were PubMed, Google Scholar, Scopus, and Web of Science. Along with this, we also report our case of vocal fold myxoma. We found a total of 19 studies reporting laryngeal myxoma. Laryngeal myxoma typically affects males in the 6th decade with a history of smoking. Unlike myxomas originating outside the larynx, recurrence is not widely described, and microlaryngeal surgery will usually suffice. Laryngeal myxomas should definitely be kept in the list of differential diagnosis when dealing with a benign-looking vocal fold lesion.

Glottic myxoma presenting as chronic dysphonia: a case report and review of the literature

Myxomas of the vocal fold are rare benign tumors often presenting with chronic dysphonia and less frequently with airway obstruction. The current consensus is that all laryngeal myxomas should be totally excised with clear margins to prevent recurrences. The recommendation for complete excision, however, has to be balanced with consideration of preserving vocal fold phonatory and sphincteric function. We report a case of vocal fold myxoma recurring twice after subtotal excision via two surgical approaches. This case illustrates a benign lesion with potential for recurrence and the need for a balanced treatment approach.
