PURPOSE
Although median raphe cysts of the penis have been widely reported the pathogenesis is obscure. We describe the microstructural detection of 3 cases of median raphe to study the true pathogenesis.
MATERIALS AND METHODS
Three patients presented to our clinic of plastic surgery complaining of abnormal shape of the penis or mass recurrence. High magnification light microscopy and electron microscopy were performed.
RESULTS
Microstructural study revealed that all 3 cases had similar findings to those of the common urethral mucosa.
CONCLUSIONS
Median raphe cysts are derived from the external paraurethral ducts and contain features that to our knowledge have not been previously reported.
目的
尽管阴茎中缝囊肿已有广泛报道，但其发病机制尚不清楚。我们描述了3例中缝囊肿的微观结构检测，以研究其真正的发病机制。
材料与方法
3例患者因阴茎外形异常或肿块复发就诊于我院整形外科。进行了高倍光学显微镜和电子显微镜检查。
结果
微观结构研究显示，所有3例病例的表现均与常见尿道黏膜相似。
结论
中缝囊肿起源于尿道外旁管，其特征据我们所知此前尚未见报道。
