Nasal Septal Angioleiomyoma and Septal Sinus Surgery: A Review of 2 Cases.

Angioleiomyomas are smooth muscle masses originating from blood vessel tunica media. This is a rare tumor, comprising less than 1% of benign sinonasal cavity tumors. Failure to recognize and surgically excise nasal angioleiomyomas can result in lesion recurrence. We present 2 new cases of nasal septum angioleiomyoma at a single institution. Additionally, both cases underwent septal and nasal surgery. Due to the nonspecific clinical and imaging findings, a high index of suspicion is needed to diagnose nasal septum angioleiomyoma, often requiring histopathological verification. Preferred treatment is complete surgical excision. From our experience, concurrent corrective septal and sinus surgery can be completed with tumors less than 1.0 cm in size.
