title: Secondary amyloidosis in Castleman's disease: review of the literature and report of a case.
abstract: It is quite rare to diagnose secondary amyloidosis during the course of Castleman's disease (CD). A 51-year-old female who complained of fatigue, weight loss, and fever was diagnosed with CD -- plasma cell type -- in our hospital in 1993. One year after diagnosis, she developed nephrotic syndrome, the etiology of which was found to be secondary amyloidosis based on renal biopsy. As the patient rejected therapy, she was discharged after only symptomatic treatment. At her last follow-up in March 2001, she had no complaints; physical examination, blood chemistries, and urinalysis were normal. Abdominopelvic tomography revealed no lymphadenopathy in the abdomen, which had been previously present. We could identify 17 other cases of CD with secondary amyloidosis in the literature. Ours is the 18th such case and the 2nd case of multicentric CD leading to amyloidosis. This case also shows that CD might sometimes run a relatively benign course being cured with no therapy, whereas it might have a rapidly fatal downhill course -- even with therapy -- in others. Still, effective treatment strategies need to be developed.
