Relapsing polychondritis: review of current status and case report,.

This communication has attempted to review the present state of published knowledge on the syndrome of relapsing polychondritis. Basic anatomic, physiologic, and biochemical changes in this disorder are summarized and the role of metabolic and immunologic alterations in the pathogenesis discussed. An additional case of relapsing polychondritis is reported, and the clinical features of this case, plus those of 131 previously reported, are reviewed with discussion of present day therapeutic experience and prognosis.

Relapsing polychondritis: an ultrastructural study.

Ear cartilage from a typical case of relapsing polychondritis was examined with the electron microscope. A large number of dense granules and vesicles, which were compatible with matrix vesicles or lysosomes, surrounded the affected chondrocytes. In less severely damaged chondrocytes, these granules and vesicles appeared to be formed by pinching off of the cytoplasmic processes or by budding from the processes. Calcification of the granules was minimal. In severely damaged chondrocytes, an admixture of these granules and cytoplasmic organelles occurred. It is speculated that many of these dense granules are lysosomal in nature and that they may produce inflammation and reduce the proteoglycan content of cartilage.
