The findings of a clinicopathological and biochemical study of epidermal cysts and a review of the relevant literature are presented. A punctum was found in 40% of 34 epidermal cysts that were studied in detail. The findings of the histological study were in favour of the punctum being the orifice of an obstructed hair follicle from which at least a proportion of the epidermal cysts are likely to develop. The biochemical analysis of the contents of the cysts revealed a very low protein and lipid content, thus ruling out any "sebaceous' contribution. Bacteriological study of clinically inflamed cysts showed that inflammation in these lesions was usually aseptic unless there was a communication between the cyst cavity and the exterior.
本文介绍了表皮囊肿的临床病理及生化研究结果，并对相关文献进行了综述。在34个接受详细研究的表皮囊肿中，40%发现有小孔。组织学研究结果支持该小孔是阻塞毛囊的开口，至少一部分表皮囊肿可能由此发展而来。囊肿内容物的生化分析显示蛋白质和脂质含量极低，从而排除了任何“皮脂腺”的作用。对临床有炎症的囊肿进行细菌学研究表明，这些病变中的炎症通常是无菌性的，除非囊肿腔与外部相通。
