title: [AL amyloidosis originally considered as systemic vasculitis].
abstract: The paper describes a sectional case of the rare unusual manifestation of AL amyloidosis in a 58-year-old woman with multiple small myocardial scars, a lung decay focus, and extensive gastric mucosal necrosis that has led to fatal hemorrhage, which was assessed as the pattern of systemic vasculitis before immunological examination. The pathogenesis of this form of AL amyloidosis is considered as a manifestation of malignant transformation of B lymphocytes.
