Extrapulmonary thoracic restriction (hidebound chest) complicating eosinophilic fasciitis.

Abstract

Eosinophilic fasciitis (EF) is an unusual disorder characterized by diffuse skin thickening and induration due to inflammation within the deep fascia; visceral involvement is generally mild or absent. A patient with biopsy-proved EF developed progressive respiratory limitation. Physical examination revealed marked induration of the thoracic integument with a severely limited chest wall excursion. Total lung capacity was 62 percent of predicted with a normal corrected Dco and maximal inspiratory force; a chest computed tomogram with thin sections showed no evidence of parenchymal lung disease. Extrapulmonary thoracic restriction ("hidebound chest") has not been previously reported to complicate EF.
