Median raphe (parameatal) cysts of the penis
1Department of Plastic and Reconstructive Surgery, Showa University Faculty of Medicine, Shinagawa, Tokyo, Japan.
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.
