[Whipple's disease with reactive (AA) amyloidosis].
A 59-year-old man had been known for two years to have a clearly elevated blood sedimentation reaction and intermittent arthralgia in the hand. His general condition had progressively deteriorated over the last six months, with weight loss, recurrent vomiting and constipation. At first malignant lymphoma had been suspected because numerous lymph nodes were enlarged. But a lymph-node biopsy revealed massive macrophages with PAS-positive inclusion material, diagnosed as Whipple's disease. The patient died suddenly of a heart attack on the day of diagnosis. At necropsy generalized amyloidosis with marked cardiac involvement was found. Immunohistochemically the amyloid deposits gave a strongly positive reaction to anti-AA, while other amyloid syndromes were excluded using appropriate anti-sera. This was therefore a case of reactive (AA) amyloidosis in the presence of Whipple's disease.
