1. Peyronie’s disease

4. Ultrasound of peyronie’s disease Calcified plaque

5. X- ray pelvis showing bilateral fibrosis of the corpora cavernosa tunica albuginea denoting peyronie’s disease ( yellow line)

6. Calcified plaque involving right corpus cavernosum ( painful erection) ( Peyronie’s disease)

7. MRI: Peyronie’s disease

8. MRI: Penile fibrosis

9. Collagen in peyronie’s disease
Collagen in peyronie’s disease. Densely packed collagen fibers prevent normal sliding of tissue during expansion & contraction of erection process resulting in a curved penis.
Collagen in normal tissue of tunica albuginea. Organized collagen fibers arranged in sheets that slide past each other during expansion & contraction of the erection process.

10. H. & E. showing fibrosis of tunica albuginea but does not affect corpora cavernosa . It may be calcified or ossified (os penis)

11. Mallory stain showing fibrosis of tunica albuginea in a case of peyronie’s disease

15. Dorsal neurovascular bundle is lifted off the underlying corporal body by a blue rubber loop. So nerve function will be preserved. The actual problem is the corporal body where incision & grafting will take place.

16. Penile fracture in a case of Peyronie’s disease

17. Penile fracture (Broken penis) It affects directly the tunica albuginea. Dignosis is by cavernosography ; MRI & urethrogrphy to rule out whether the urethra is traumatized, No bone inside cavernous tissue.
