Laryngeal angioleiomyoma: A case report of 52-year-old female

Abstract

Introduction: Laryngeal angioleiomyoma is a rare benign tumor of larynx with vascular origin. We report a case of laryngeal angioleiomyoma in a 52-year-old female. Case presentation: A 52- year-old Caucasian female was referred to our institute with a chief compliant of severe midnight snoring. Her symptoms were progressive and began from two years ago. There was no history of hoarseness and laryngeal pain. The patient underwent a laryngoscopic examination and a large mass was seen on the left aryepiglotic fold. Surface of lesion was smooth and covered by laryngeal mucosa with no ulcer. There was a rapid enhancing mass on left aryepiglotic fold with bulging into the left piriformis sinus in contrast-enhanced computed tomography. The tumor was complicated by profuse bleeding after biopsy which was not controlled by conventional approaches. The patient was then administered a general anesthesia and the tumor was completely removed via laryngosurgery accompanied by left superior thyroid artery ligation. The specimen was histopathologically compatible with laryngeal angioleiomyoma. Conclusion: Angioleiomyoma of larynx is of benign nature and rarely recurs. However, it can be complicated by profuse bleeding on biopsy and contrast-medium imaging should be considered before surgical intervention to diagnose the tumor properly and prevent life-threatening complications.
