Myoepithelioma of nasal septum: a rare minor salivary gland tumour

Abstract

Myoepithelioma is rare benign neoplasm, usually involves salivary glands and very less often seen in minor salivary glands of nose. Clinically it resembles like other tumour masses and thus posed challenge to clinician and pathologist. It becomes very difficult to diagnose due to its varied presentation and propensity for malignant transformation. We reported a case of a male patient with pink fleshy mass in the left nose with epistaxis and nasal obstruction. Preliminary biopsy and contrast-enhanced CT were done to delineate tumour size and type and then patient underwent endoscopic en-bloc resection. Histopathology and immunohistochemistry were found to be consistent for myoepithelioma. No recurrence was seen during a 6-month follow-up period. Its rarity should be a part of differential diagnosis among nasal tumours. Many of the tumour recurrences are associated with incomplete surgical resection so wide local excision with regular follow-up is essential for this rare entity.

Imaging features of a myoepithelial carcinoma of the nasal cavity: A case report and literature review

“…The imaging characteristics of myoepitheliomas and myoepithelial carcinomas of the nasal cavity have not been well described. In the published cases for nasal myoepitheliomas [7] , [8] , [9] , [10] , the CT showed nasal soft tissue densities with or without deviated nasal septum. Contrast enhancement by contrast medium varies from case to case and has no constant tendency for the contrast effect on contrast-enhanced CT [ 7 , 9 , 10 ].…”
