Abstract
<p> We encountered two cases of pleomorphic adenoma arising from the nasal septum, which were resected by endoscopic intranasal operation.<br></p><p> Case 1: A 70-year-old woman was admitted to our hospital with the complaint of epistaxis. Endoscopic examination revealed a mass with a smooth surface located in the nasal septum. Nasal enhanced CT revealed a well-circumscribed solid mass with slight rim enhancement in the right nasal cavity, with no evidence of bone destruction. On contrast MRI, the tumor was visualized as a low signal intensity on T1-weighted images and as a high signal intensity on T2-weighted images.<br> Case 2: A 56-year-old man presented to us complaining of right-sided epistaxis. Examination revealed a hemorrhagic mass with a smooth surface located in the nasal septum. Nasal enhanced CT scan revealed a well-circumscribed solid mass with slight enhancement of the rim in the right nasal cavity, with no evidence of bone destruction. On MRI, the tumor was visualized as a iso signal intensity on T1-weighted images and as a high signal intensity on T2-weighted images.<br> Pleomorphic adenoma usually occurs in the major salivary glands, and rarely arises from the nasal septum. Pleomorphic adenoma has also been reported to rarely show malignant transformation, which indicates the need for careful postoperative observation of the patients.</p>
