Mechanisms of Calcification in Peyronie’s Disease

Abstract

Scanning and transmission electron micrographs demonstrate a calcification process in the penile plaques of patients with Peyronie's disease. Osteoid formation originates from vascular lumina via osteoblast-like cells, which align the calcified plaque. These cells are surrounded gradually by calcified connective tissue. Collagen fibers demonstrate calcification and decreased periodicity.
