Treatment of extensive post tonsillectomy oropharyngeal stenosis secondary to fibromatosis

Summary

Aggressive fibromatosis is an uncommon, benign tumor of fibroblastic origin with high potential for local invasion. Less than a quarter of these lesions are located in the head and neck, and although extremely rare, associations have been demonstrated with physical trauma. We describe a unique case of oropharyngeal fibromatosis with traumaticetiology, managed successfully with surgical excision of the lesion with negative surgical margins. A 5-year old patient was found to have an aggressive fibromatosis causing oropharyngeal stenosis following tonsillectomy. We demonstrate that surgical resection with a clear margin allowed for alleviation of stenosis without recurrences reported since the procedure.
