A 65-year-old woman consulted our hospital complaining of left nasal obstruction. On nasal examination, a reddish half round tumor arising from the left nasal septum was found. We removed the tumor together with normal septal mucosa. Histologically, the tumor was diagnosed as a hemangiopericytoma-like tumor. It has been reported that a hemangiopericytoma-like tumor is microscopically distinguished from similar type tumors arising from other sites of the body. The most notable microscopic features of intranasal hemangiopericytoma-like tumors are their uniformity of cells and the absence of nuclear or cytoplasmic pleomorphism with a sheetlike arrangement, and no evidence of varying growth phases or necrosis. This is the second case report of this type of tumor in Japan.
一名65岁女性因左侧鼻塞前来我院就诊。鼻腔检查发现，左侧鼻中隔有一个微红的半圆形肿物。我们将肿物连同正常的鼻中隔黏膜一并切除。组织学检查显示，该肿瘤被诊断为血管外皮细胞瘤样肿瘤。据报道，血管外皮细胞瘤样肿瘤在显微镜下可与身体其他部位发生的类似肿瘤相区分。鼻内血管外皮细胞瘤样肿瘤最显著的显微镜特征是细胞均匀一致，无核或胞质多形性，呈片状排列，且无不同生长阶段或坏死的迹象。这是日本该类型肿瘤的第二例病例报告。
