Peyronie's disease is a connective tissue disorder involving the growth of fibrous plaques in the soft tissue of the penis. Specifically, scar tissue forms in the tunica albuginea, the thick sheath of tissue surrounding the corpora cavernosa, causing pain, abnormal curvature, erectile dysfunction, indentation, loss of girth and shortening.[2][3]

It is estimated to affect between .4 to 20% of men.[2] The condition becomes more common with age.[2] A certain degree of curvature of the penis is considered normal, as many people are born with this benign condition, commonly referred to as congenital curvature.[4] The disease may cause pain; hardened, big, cord-like lesions (scar tissue known as "plaques"); or abnormal curvature of the penis when erect due to chronic inflammation of the tunica albuginea (CITA).[5]

Although the popular conception of Peyronie's disease is that it always involves curvature of the penis, the scar tissue sometimes causes divots or indentations rather than curvature. The condition may also make sexual intercourse painful and/or difficult, though it is unclear whether some men report satisfactory or unsatisfactory intercourse in spite of the disorder.[citation needed] The disorder is confined to the penis, although a substantial number of men with Peyronie's exhibit concurrent connective tissue disorders in the hand, and to a lesser degree, in the feet. About 30 percent of men with Peyronie's disease develop fibrosis in other elastic tissues of the body, such as on the hand or foot, including Dupuytren's contracture of the hand. An increased incidence in genetically related males suggests a genetic component.[6] It can affect men of any race and age.
Psychosocial

Peyronie's disease can also have psychological effects. While most men will continue to be able to have sexual relations, they are likely to experience some degree of erectile dysfunction. It is not uncommon to exhibit depression or withdrawal from their sexual partners.[7]
Causes

The underlying cause of Peyronie's disease is unknown. Although, it is likely due to a buildup of plaque inside the penis due to repeated mild sexual trauma or injury during sexual intercourse or physical activity.[8]

Risk factors include diabetes mellitus, Dupuytren's contracture, plantar fibromatosis, penile trauma, smoking, excessive alcohol consumption, genetic predisposition, and European heritage.[9][10][11]
Diagnosis
This ultrasound depicts cross sections of the penis at different locations in a patient with Peyronie's disease. The top image shows normal anatomy whereas the bottom image shows scar tissue on the tunica albuginea (penis). The scar tissue is localized and responsible for the hallmark deformities of Peyronie's disease (curvature and narrowing).

A urologist may be able to diagnose the disease and suggest treatment. An ultrasound can provide conclusive evidence of Peyronie's disease, ruling out congenital curvature or other disorders.[12]
Ultrasonography

On penile ultrasonography, the typical appearance is hyperechoic focal thickening of the tunica albuginea. Due to associated calcifications, the imaging of patients with Peyronie's disease shows acoustic shadowing, as illustrated in figures below. Less common findings, attributed to earlier stages of the disease (still mild fibrosis), are hypoechoic lesions with focal thickening of the paracavernous tissues, echoic focal thickening of the tunica without posterior acoustic shadowing, retractile isoechoic lesions with posterior attenuation of the beam, and focal loss of the continuity of the tunica albuginea. In the Doppler study, increased flow around the plaques can suggest inflammatory activity and the absence of flow can suggest disease stability. Ultrasound is useful for the identification of lesions and to determine their relationship with the neurovascular bundle. Individuals with Peyronie's disease can present with erectile dysfunction, often related to venous leakage, due to insufficient drainage at the site of the plaque. Although plaques are more common on the dorsum of the penis, they can also be seen on the ventral face, lateral face, or septum.[13]
