A Case of Recurrent Glomus Tumor Arising in the Sphenoid Sinus

Abstract

Glomus tumor, also known as glomangioma, is a specialized arteriovenous anastomosis usually found in the skin of the extremities. This rare tumor is seldom located in the nasal cavity or paranasal sinuses. Here in we present a case of recurrent glomus tumor in the sphenoid sinus, which is the first reported case to our knowledge. We successfully resected the tumor using an endonasal, endoscopic approach after embolization of the feeding arteries. Histopathologic examination revealed the recurrence of the glomus tumor. The control of intraoperative bleeding is crucial for the complete excision of this tumor through an endonasal, endoscopic approach.
