Popis: | Five patients with Peyronie's disease were operated and the tissue specimens from the plaque involving the tunica albuginea and from the tunica of the unaffected contralateral side were obtained. The specimens were then subjected to histopathological examination and the findings were correlated with those of men proved not to have Peyronie's disease but operated for other reasons. In the specimen of plaque, the changes varied from collagen destruction to cartilaginous and osseous metaplasia. However, in the tunica of the contralateral side the changes such as disregularity of collagen bundles extending even to widespread focal areas, and appearance of pale, rough, eosinophilic collagen degeneration, instead of its characteristic bright birefringence, and focal mucinous degeneration were noted. Interestingly, these alterations were not observed in the specimens of normal tunica albuginea in the control group. But the existence of minimal alterations, the regularity in the apparently normal contralateral tunica albuginea specimens in Peyronie's disease implied that there was an active turnover in collagen production, and the possible factor causing collagen degeneration and so plaque formation was probably the microtraumatization of the tunica albuginea. |
