Encyclopedia
Relapsing polychondritis (also known as "Atrophic polychondritis," and "Systemic chondromalacia") is a condition characterized by deterioration of cartilage

It is also known as chronic atrophic polychondritis, Meyenburg-Altherr-Uehlinger syndrome, von Meyenburg's disease, generalized chondromalacia, and systemic chondromalacia.

Presentation

Though any cartilage in the body may be affected, in many cases the disease affects several areas while sparing others completely. Parts of the body where cartilage is found, and therefore potentially affected by polychondritis, include the ear

Onset

While the disease may first present at various times, it most frequently presents in the late 40's to early 50's. Some literature reports a slightly higher occurrence in females than males, while other authors assert that sex is not a statistically significant factor in the incidence of the disease.
