title: Circumferential Peyronie's disease involving both the corpora cavernosa.
abstract: An extraordinary form of Peyronies disease is reported. The patient was a 52 year old male, who died of a malignant thymoma with multiple bone metastasis, extensive pleural carcinomatosis of the left lung and some metastatic nodules in the liver and the mesenterium. At autopsy, the proximal and middle portions of the penis were very hard. Macroscopically, the entire tunica albuginea of both the corpora cavernosa was markedly thickened, 2-4 mm; and calcified. Microscopically, the tunica albuginea showed extensive hyaline degeneration, calcification and ossifying foci with osteoblasts and osteoclasts. Inflammatory cells were frequently found beneath the thickened tunica albuginea. In the corpus cavernosum, cavernous arteries showed marked intimal thickening and medial muscular degeneration with a few inflammatory cells. Smooth muscles of the stroma were extensively atrophic and degenerative, and some of them were infiltrated with a few inflammatory cells. In the corpus spongiosum, the tunica albuginea was not thickened, but the smooth muscle in the stroma was atrophic and degenerative and a few inflammatory cells were also found. Surprisingly, there was no Littrés gland around the urethra. In Peyronies disease, the dorsal part of the penis is usually involved, and less frequently lateral or ventral sites are involved. The circumferential involvement of both the corpora cavernosa has not been reported until now, as far as the authors know.
