Median raphe (parameatal) cysts of the penis

T Otsuka et al. J Urol. 1998 Jun.

Abstract

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.
