Laryngeal synovial sarcoma : report of 2 cases

الملخص EN

Synovial sarcoma is a malignant mesenchymal tumor.

It most commonly occurs in the lower extremities of young adults.

The head and neck are rare sites, accounting for less than 10%.

The larynx is an extremely rare site.

We report two cases of 27 and 18 year-old men who developed a synovial sarcoma of the larynx.

They presented with hoarseness of voice and hemoptysis.

Endoscopy detected a mass in the supraglottic region.

The biopsy concluded a synovial sarcoma.

Immunohistochemistry conveyed diagnostic certainty.

They had been treated with total laryngectomy and post-operative radiotherapy.

The 2 patients are seen for regular follow-ups in our department and they remained recurrence-free for 10 years and 24 months, respectively.

Synovial sarcoma is a very rare tumor of the larynx.

A multidisciplinary therapeutic approach is essential for the management of this malignancy.

Long-term follow-up is required to monitor for recurrence and improve disease-free survival
