Pleomorphic adenoma in the otorhinolaryngological field is frequently found in the major salivary glands, but is rare in minor salivary glands. Two cases of pleomorphic adenoma of the nasal cavity are reported. Case 1. A 26-year-old female who complained of nasal obstruction had a tumor arising from the right side of the nasal septum. The tumor, 1.5 x 1.5 x 1.2cm in size, was surgically removed utilizing an intranasal approach. Histologically, it was diagnosed as a pleomorphic adenoma of the nasal septum. There has been no recurrence. Case 2. A 51-year-old male had a tumor in the left lateral nasal wall. The tumor, 0.6 x 0.6 x 0.6 cm in size, was surgically removed by the intranasal approach. Histologically, it was diagnosed as a pleomorphic adenoma of the lateral nasal wall. There has been no recurrence. Including the present cases, 59 cases of pleomorphic adenoma arising from the nasal cavity have been reported in Japan. Of these, 51 arose from the nasal septum. Only 8 adenomas had arisen from the lateral nasal wall. Attention has been called especially to differences in the reported incidences of malignant tumors and recurrent tumors. In the present survey, the incidences were unusually low. Four cases (6.8%) have been reported as malignant tumors, and 3 (5.1%) as recurrent tumors.
耳鼻喉科领域的多形性腺瘤常见于大唾液腺，但在小唾液腺中罕见。本文报告了两例鼻腔多形性腺瘤病例。病例1. 一名26岁女性，因鼻塞就诊，发现鼻中隔右侧有一肿瘤。肿瘤大小为1.5×1.5×1.2cm，经鼻内途径手术切除。组织学检查诊断为鼻中隔多形性腺瘤。术后无复发。病例2. 一名51岁男性，左侧鼻侧壁有一肿瘤。肿瘤大小为0.6×0.6×0.6cm，经鼻内途径手术切除。组织学检查诊断为鼻侧壁多形性腺瘤。术后无复发。包括本病例在内，日本已报告59例鼻腔多形性腺瘤。其中，51例起源于鼻中隔，仅8例起源于鼻侧壁。特别值得注意的是，文献报道的恶性肿瘤和复发性肿瘤的发生率存在差异。在本次调查中，发生率异常低。有4例（6.8%）报告为恶性肿瘤，3例（5.1%）报告为复发性肿瘤。
