Pleomorphic adenoma of nasal septum: A rare case

The most common benign tumour of the major salivary glands is the pleomorphic adenoma. They are seen rarely in the minor salivary glands, usually in hard palate, soft palate and nasopharynx. Pleomorphic adenomas in nasal cavity are unusual and may be misdiagnosed because they have predominant myoepithelial cellularity and fewer myxoid stromata compared with those elsewhere. We present a case of 38-year-old male with a 2-year history of left nasal obstruction and epistaxis since 6 months. Diagnostic nasal endoscopic examination showed a soft lobulated mass in left nasal cavity attached to anterior part of the septum. Radiological examination demonstrated soft tissue mass filling left nasal cavity with an eroded septum. The biopsy from the mass was suggestive of pleomorphic adenoma and was resected endoscopically. Histopathological examination was consistent with pleomorphic adenoma. These are rare tumours of the nasal cavity and can be managed effectively with the endoscopic approach.
