[Haemorrhagic diathesis as an early symptom of systemic amyloidosis].
METHODS
A 63-year-old man, known to have Bechterev's disease was admitted because of weight gain and nocturnal sweating. He also had signs of heart failure with progressive exertional dyspnoea. Many months previously numerous bleedings had occurred in the skin, predominantly the face (periorbital and perioral), the inguinal region and the penis.


METHODS
Extensive diagnostic test failed to find any evidence of tumor. The Rumpel-Leede tourniquet test was positive, while platelet functions was normal, suggesting vascular disease. The skin biopsy showed many perivascular amyloid deposits (AL). Immunochemical differentiation also demonstrated the same amyloid in rectal and hepatic biopsies. But there was AA amyloid in a hepatic artery. Immunophoresis indicated a biclonal gammopahty of unknown significance.


METHODS
These findings indicated the diagnosis of primary AL amyloidosis associated with a gammopathy of unknown significance and a secondary AA amyloidosis in the presence of chronic Bechterev s disease. The clinical picture also showed cardiac complications, predominantly heart failure and numerous previous myocardial infarctions without S-T elevations. Echocardiography, which revealed marked thickening of the left ventricle with a restrictive filling pattern, suggested cardiac co-morbidity. The patient underwent chemotherapy with melphalan and prednisone but had a sudden cardiac death.


CONCLUSIONS
In a case of bleeding of unknown cause systemic amyloidosis should be considered in the differential diagnosis. A tendency towards bleeding, as in this patient, may be the first sign of amyloidosis, which ist often diagnosed quite late in the course of the disease.
