Naso-ethmoidal angioleiomyoma: a mini-invasive combined endoscopic and microscopic surgical approach

Background: Angioleiomyomas of the paranasal sinuses are extremely rare benign tumors, representing less than1% of all leiomyomas in the human body.Methods: A case report is presented describing a patient with a tender mass growing in the subcutaneous tissuewith right nasal obstruction.Results: Transnasal surgical resection was performed through a combined use of endoscopy and microscopyapproach. Histological examination revealed the presence of vascular formations with thick muscular wall and abundantfibrous connective stroma, with a diagnosis of angioleiomyoma.Conclusion: In cases of rare benign tumors of the naso-ethmoidal region, such as angioleiomyomas, a microscopicexcision was performed with endoscopic confirmation of tumour resection from recesses not visualized microscopically.This mini-invasive avoids facial demolition and disfiguring surgery as well as external scars of the facial skin.
