作者们于4例慢性鼻窦炎并发的鼻息肉组织切片中见到有胆固醇结晶形成。4例均为成人,年龄24～57岁,平均43岁。3男1女。鼻息肉均发生在中鼻道。4例中有3例胆固醇结晶是在鼻息肉内的小囊泡积液中找到的,另1例系在鼻息肉粘膜上皮下广泛发现胆固醇肉芽肿。作者们推测鼻息肉内的小囊泡可能是鼻粘膜腺体因炎症病变分泌液贮留形成积液囊泡,后来积液又析出胆固醇结晶。4例中有2例并发变应性鼻炎,变态反应是否可促使鼻息肉组织内出现胆固醇结晶值得进一步探讨。鼻息肉粘膜上皮下广泛发生胆固醇肉芽肿的一例,鼻镜检查可见鼻息肉呈暗青色,与中耳胆固醇肉芽肿时鼓膜呈蓝色相似,表
The authors found cholesterol crystals in four cases of nasal polyps with chronic sinusitis. 4 cases were adults, aged 24 to 57 years, mean 43 years. 3 men and 1 woman. Nasal polyps occur in the middle nasal passages. Cholesterol crystals were found in 4 of 4 cases of small vesicle effusion in the nasal polyps, while the other 1 case was found extensively in the nasal polyps mucosal epithelium of cholesterol granuloma. The authors speculate that small vesicles in the nasal polyps may be secreted by the nasal mucosal glands secreted by the inflammatory glands to form fluid-containing vesicles, which accumulate cholesterol crystals. In 4 cases, 2 cases were complicated with allergic rhinitis, and whether allergic reaction could promote the occurrence of cholesterol crystals in nasal polyps deserved to be further explored. Nasal polyps under the epithelial mucosal widespread occurrence of cholesterol granuloma cases, nasal examination showed nasal polyps dark blue, and the middle ear when the tympanic membrane of cholesterol granuloma blue similar table
