A rare case of sinonasal glomangiopericytoma post operative accidental diagnosis and managment—A case report

Abstract

Highlights Glomangiopericytoma is rare sinonasal disease with very good prognosis after surgical excision. Prognosis is very good after surgical excision. As most nasal tumors our case was also an accidental diagnosis following endoscopic sinus surgery. and complete clearance was suspicious. Patent was referred for adjuvant radiation. Revision surgery was done and wide clearance was established. Patient was saved from radiation.

“… Michihisa Kono et al [ 11 ] CT A mass occupying the right nasal cavity with strong enhancement. Nitin Sharmaa et al [ 22 ] CT Polypoidal mucosal thickening in sphenoid sinus with complete opacification. There was hyperdensity without any abnormal enhancement, but mild focal extension of soft tissue was seen in sphenoethmoidal recess left side and protruding into nasopharynx.…”

Sinonasal Glomangiopericytoma with Prolonged Postsurgical Follow-Up

“…SNGPC most commonly presents with epistaxis, nasal obstruction, and headache, though advanced disease can cause facial pain, bulging, and proptosis [9][10][11]. Cases of misdiagnosis as benign nasal polyps have been previously reported [12].…”

“…[9][10][11] Cases of misdiagnosis as benign nasal polyps have been previously reported. 12 The management of SNGPC consists mainly of total surgical resection. This is typically performed endoscopically, 13 but open approaches via medial maxillectomy have also been reported in advanced cases.…”

A case report of sinonasal glomangiopericytoma: An important reminder to always collect specimen

“… 2 , 3 GPC tumors have low malignant potential and are reported to represent less than 0.5% of sinonasal neoplasms. 4 – 9 The definition of the disease has a complex history since the first report in 1942 describing this as hemangiopericytoma. 10 While initially thought to be within the spectrum of vascular tumors ranging from capillary hemangioma to glomus tumors, GPC has been classified as a distinct entity by the World Health Organization since 2005.…”
