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.
大唾液腺最常见的良性肿瘤是多形性腺瘤。它们在小唾液腺中很少见，通常发生于硬腭、软腭和鼻咽部。鼻腔内的多形性腺瘤并不常见，可能会被误诊，因为与其他部位的多形性腺瘤相比，其肌上皮细胞占主导且黏液样基质较少。我们报告一例38岁男性患者，自6个月前起有2年左侧鼻塞和鼻出血病史。诊断性鼻内镜检查显示左侧鼻腔有一个柔软的分叶状肿物，附着于鼻中隔前部。影像学检查显示软组织肿物充满左侧鼻腔，鼻中隔有侵蚀。肿物活检提示为多形性腺瘤，并通过内镜切除。组织病理学检查结果与多形性腺瘤一致。这些是鼻腔的罕见肿瘤，可通过内镜方法有效治疗。
