A case of immunotactoid glomerulopathy with false-negative IgG staining

Fibrillary glomerulonephritis and immunotactoid glomerulopathy.

Fibrillary glomerulonephritis is a now widely recognized diagnostic entity, occurring in approximately 1% of native kidney biopsies in several large biopsy series obtained from Western countries. The distinctive features are infiltration of glomerular structures by randomly arranged fibrils similar in appearance but larger than amyloid fibrils and the lack of staining with histochemical dyes ty...

Immunotactoid glomerulopathy and tuberculosis: a novel association.

Immunotactoid glomerulopathy associated with mycosis fungoides.

A patient with mycosis fungoides developed a nephrotic syndrome. Renal biopsy revealed deposits of a highly organized fibrillar material which did not stain with the typical amyloid stains; this picture was consistent with the diagnosis of non-amyloidotic fibrillary glomerulopathy or immunotactoid glomerulopathy. We believe this is the first case reported of immunotactoid glomerulopathy associa...

A Case of Immunotactoid Glomerulopathy with Rapid Progression to End-Stage Renal Disease

Immunotactoid glomerulopathy (IGN) is a rare immunoglobulin deposition disease. It is often mistaken for cryoglobulinemia or amyloidosis due to the similarities on biopsy findings. The disease progresses to end-stage renal disease (ESRD) within 7 months to 10 years. This is the first case reported of a patient with a diagnosis of IGN who developed acute kidney injury (AKI) and ESRD within 1 wee...

A case report of POEMS syndrome with renal involvement as immunotactoid glomerulopathy

RATIONALE POEMS syndrome is a rare multi-system disorder, which sometimes involves the kidney. Immunotactoid glomerulopathy (ITG) is an uncommon glomerular disease resulted from deposits of immunoglobulins and its derivatives. ITG caused by POEMS syndrome is rarely reported. PATIENT CONCERNS A 63-year-old man was presented with acute kidney injury. In addition, it's found that he had abnormal...
