To determine the distinction between a comedo and an infundibular cyst of Favre-Racouchot disease.
A university hospital.
From the 8 patients included in the study, 19 cysts and comedones were evaluated.
The distinguishing features between the cysts and comedones of Favre-Racouchot disease.
All lesions were histologically indistinguishable from the primary comedones of acne vulgaris, except for the presence of a marked actinic elastosis in the surrounding dermis. The presence of a variable number of hair shafts and an abundant amount of bacteria, which was positive in the results of Gram staining and periodic acid-Schiff reaction and intermingled with sebum and eosinophilic laminated horny material within the dilated infundibulum, characterizes a comedo and differentiates it from an infundibular cyst.
The cysts and comedones of Favre-Racouchot disease are closed and open comedones. They can be easily differentiated from an infundibular cyst by the histopathologic features rather than by the connection to the surface.
确定法夫尔-拉库肖病的粉刺与漏斗状囊肿之间的区别。
一家大学医院。
在纳入研究的8名患者中,对19个囊肿和粉刺进行了评估。
法夫尔-拉库肖病囊肿与粉刺的鉴别特征。
所有病变在组织学上与寻常痤疮的原发性粉刺无明显差异,只是周围真皮存在明显的光化性弹力纤维变性。粉刺的特征是在扩张的漏斗状结构内存在数量不等的毛干和大量细菌,革兰氏染色和过碘酸-希夫反应结果呈阳性,且与皮脂和嗜酸性层状角质物质混合,这使其与漏斗状囊肿区分开来。
法夫尔-拉库肖病的囊肿和粉刺分别为闭合性和开放性粉刺。它们可通过组织病理学特征而非与表面的连接情况与漏斗状囊肿轻易区分开来。
