[Abnormalities of the male median raphe]
1Service de dermatologie, hôpital Saint-Louis, AP-HP, 1, avenue Claude-Vellefaux, 75010 Paris, France.
Introduction:
Abnormalities of the male median raphe can either be detected during postnatal examination or appear later during childhood or adulthood. They can be isolated or sometimes associated with severe congenital genitourinary malformations.
Methods:
A literature review was performed on the Medline database, considering the articles listed until April 2015 dealing with abnormalities of the male median raphe using the following keywords: male, median raphe and abnormalities. Papers were selected according to their language (English and French) and their relevance.
Results:
Forty-one articles related to male median raphe abnormalities were listed. Five of them were selected for their relevance. We describe frequent median raphe abnormalities (hyperpigmentation, deviation, division, cyst, canal and sinus), emphasizing the clinical aspects, the explorations, the risk of associated genitourinary abnormalities and the treatment.
Discussion:
Male raphe abnormalities should be known by the urologists since functional, infectious and aesthetic complications could lead patients to consultation.
