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

INTRODUCTION: Glomangiopericytoma is a rare neoplasm of low malignant potential. It is a rare type of haemangiopericytoma located in nasal cavity. This neoplasm has good prognosis and complete surgical excision is treatment of choice. This case report is representing one such neoplasm. This reporting is done in line with the SCARE criteria (Agha et al., 2018 [1]). CASE PRESENTATION: We presenting a case of 54 year old male patient from upper socioeconomic status who presented at our institution with history of surgery (endoscopic sinus surgery with Septoplasty) 15 days back. A Final histopathology report suggested glomangiopericytoma. Since primary surgery was not done as per oncologic principals, patient was advised for adjuvant radiation. At our institute patient was evaluated again. Revision surgery was done. Patient was discharged next day. DISCUSSION: Glomangiopericytoma is a rare neoplasm with incidence of less than 0.5% of all neoplasms of sinonasal cavity. Prognosis is very good after complete surgical excision. It often confuses clinicians with nasal polyps. Here also patient was operated initially considering as benign polyposis outside. Patient was re-operated again to ensure the complete clearance. CONCLUSION: This is the typical case of converting dual modality treatment to single modality with the help of knowledge, communication, transparent team work. This also a rare type of neoplasm and by reporting this rare case we are contributing to data pool of nasal tumors where lack of reporting is major obstacle in the formation of uniform treatment guidelines.
