Lobular capillary hemangioma (LCH) is a benign capillary proliferation with a microscopically distinctive lobular architecture, composed of small to medium-sized vessels of capillary type. Rarely, it originates from the mucosa of the nasal cavity, most frequently from the anterior nasal septum, turbinates, and nasal vestibule. Etiology is unclear, but previous investigations suggest that this lesion is associated with injury, hormonal factors, some viral infections, and therapy with some drugs. We present a case of LCH arising from the medial wall of the maxillary sinus in a 15-year-old boy, which was completely excised by preoperative embolization and endoscopic sinus surgery. To our knowledge, this is the second reported case of an LCH originating from the maxillary antrum. Etiology, pathogenesis, diagnosis, and treatment modalities of LCH were also discussed.
小叶状毛细血管瘤（LCH）是一种良性毛细血管增生，具有显微镜下独特的小叶结构，由小到中等大小的毛细血管型血管组成。它很少起源于鼻腔黏膜，最常见于鼻中隔前部、鼻甲和鼻前庭。病因尚不清楚，但先前的研究表明，这种病变与损伤、激素因素、某些病毒感染以及某些药物治疗有关。我们报告一例15岁男孩上颌窦内侧壁发生的LCH，通过术前栓塞和鼻内镜鼻窦手术将其完全切除。据我们所知，这是第二例报告的起源于上颌窦的LCH病例。本文还讨论了LCH的病因、发病机制、诊断及治疗方式。
