title: Congo red-negative amyloidosis-like glomerulopathy.
abstract: Three cases of amyloidosis-like glomerulopathy are presented in which renal amyloidosis was initially diagnosed on the basis of ultrastructural findings, despite negative Congo red staining. The histologic and immunofluorescence findings and, on careful examination, ultrastructural features of this amyloidosis-like glomerulopathy all serve to distinguish it from true amyloidosis. The clinical behavior suggests that it is a primary glomerulopathy since, with time, no other systems become involved.
