Polychondritis recurrens

Clinical signs

rare disease of autoimmune origin
recurrent inflammation of the cartilage
affects the cartilage of the ears, nose, larynx and trachea
accompanied by arthritis, eye inflammation and other problems
skin is affected in about one third of patients (vasculitis, panniculitis, pigmentation changes and other)
one half of patients survives 10 years

Histology

Bilateral inlammation, fibrosis, destruction of the cartilage.
