NON RARE IN EUROPE: Peyronie syndrome

Peyronie syndrome, also known as Peyronie disease or penile fibromatosis (Orphanet code 2870; ICD-10: N48.6), is a connective tissue disorder affecting the penis. It is characterized by the formation of fibrous plaques (scar tissue) within the tunica albuginea, the tough sheath surrounding the erectile tissue of the penis. These plaques can cause penile curvature, pain during erection, erectile dysfunction, and penile shortening or narrowing. The condition primarily affects the genitourinary system and can have significant psychological impact, including anxiety and depression related to sexual function. Peyronie disease typically presents in two phases: an acute inflammatory phase lasting 6 to 18 months, during which pain and progressive curvature develop, followed by a chronic stable phase where the plaque calcifies and the deformity stabilizes. The exact cause is not fully understood, but it is believed to result from repeated microtrauma to the penis during sexual activity, leading to abnormal wound healing in genetically susceptible individuals. Risk factors include age, family history, connective tissue disorders (such as Dupuytren contracture), diabetes, and certain lifestyle factors. Treatment options depend on disease phase and severity. During the acute phase, conservative management may include oral medications (such as pentoxifylline or potassium para-aminobenzoate), intralesional injections (collagenase Clostridium histolyticum is the only FDA-approved pharmacological treatment), and traction therapy. In the chronic stable phase with significant curvature or erectile dysfunction that impairs sexual function, surgical options include plication procedures, plaque incision or excision with grafting, or penile prosthesis implantation. This condition is classified as non-rare in Europe, with prevalence estimates suggesting it affects a notable proportion of adult men.
