慢性出血性坏死性息肉样上颌窦炎,目前认识尚不一致,故命名较混乱。有“血管瘤型息肉”、“出血性鼻-鼻窦息肉”、“鼻腔鼻窦出血性坏死性息肉”等。其临床表现酷似恶性肿瘤,需病理检查明确诊断。我们收治3例,特报告如下。例1,男,29岁,1981年8月13日入院。左侧鼻塞,反复出血1年多,进行性加重3个月。检查:左鼻腔被息肉样肿物填满,表面坏死,易出血。X线摄片 Chronic hemorrhagic necrotic polypoid maxillary sinusitis, the current understanding is not consistent, so the name is more confusion. A “hemangioma polyp”, “hemorrhagic nasal polyps,” “nasal sinus hemorrhagic necrotic polyps” and so on. Its clinical manifestations resembled malignant tumors, requiring a clear diagnosis of pathological examination. We treated 3 cases, special report is as follows. Example 1, male, 29 years old, admitted to hospital on August 13, 1981. Left nasal congestion, repeated bleeding for more than a year, progressive increase 3 months. Check: left nasal polyp mass was filled, the surface necrosis, bleeding easily. X-ray film
