RESUMO
Four patients fulfilling the case definition for eosinophilia-myalgia syndrome are described, including one whose disease began in 1986. Each displayed a variety of symptoms: one suffered principally from myalgia and recovered spontaneously on discontinuation of L-tryptophan therapy; one exhibited progressive sclerodermiform skin changes, neuropathy, and myopathy; a third had prominent neuromuscular disease and sclerodermiform skin changes; and the fourth experienced profound weight loss, an axonal polyneuropathy, and perivascular lymphoid infiltrates simulating a lymphoma. Evidence of T-cell activation was present in peripheral blood and affected tissues during the clinically active progressive phase of disease. Among other manifestations pleural effusion, cutaneous vasculitis, joint contractures, and bloody diarrhea were observed. A history of L-tryptophan ingestion should be sought in patients with myalgia, fatigue, or the above outlined symptoms.

Pulmonary hemorrhage in a patient with Henoch-Schönlein purpura was shown at autopsy to be caused most likely by Goodpasture's syndrome. The diagnosis was missed in part because of repeated negative assays for glomerular basement membrane antibodies. Linear fluorescence for immunoglobulin G was found in lung and glomeruli at postmortem. Development of Goodpasture's syndrome might be a result of release of glomerular basement membrane antigen by vasculitis.
