Introduction Vascular leiomyoma of the nasal cavity is an extremely rare tumor that represents less than 1% of all vascular leiomyomas. It is more prevalent in women between the fourth and sixth decades, reaching primarily the inferior nasal turbinates. Objectives Reporting and assisting the systematization of more accurate diagnostic methods in clinical and complementary investigation of vascular leiomyoma in the nasal cavity. Resumed Report We present the case of a 49-year-old woman diagnosed with vascular leiomyoma in the nasal cavity, which manifested mainly with nasal obstruction. During investigation, computer tomography was not diagnostic, the cytologic study was not conclusive, and according to the biopsy, it was a squamous papilloma. Conclusion We suggest that the technical difficulty in obtaining an adequate amount of material for preoperative biopsy, associated with the topography of the lesion in the vestibular nasal region, may have contributed to changing the postoperative diagnosis. Thus, pathologic study of the surgical fragment is the more accurate method for diagnosis.
鼻腔血管平滑肌瘤是一种极为罕见的肿瘤，占所有血管平滑肌瘤的比例不到1%。它在40至60岁的女性中更为常见，主要累及下鼻甲。目的：报告并协助系统化鼻腔血管平滑肌瘤临床及辅助检查中更准确的诊断方法。简要报告：我们呈现了一例49岁女性鼻腔血管平滑肌瘤的病例，主要表现为鼻塞。在检查过程中，计算机断层扫描未明确诊断，细胞学研究也无定论，根据活检结果诊断为鳞状乳头状瘤。结论：我们认为，由于在前庭鼻区域获取足够量术前活检材料存在技术困难，加之病变部位的原因，可能导致术后诊断改变。因此，手术标本的病理研究是更准确的诊断方法。
