RESUMO
ABSTRACT Introduction: Idiopathic nodular glomerulosclerosis (ING) is a condition that has a vasculopathic glomerular histological pattern. Case presentation: The authors present the case of a 44-year-old Hispanic smoker female with hypertension and peripheral arterial disease who presented nephrotic syndrome for 2 weeks. The patient was diagnosed with ING by percutaneous renal biopsy results, which showed global nodular mesangial matrix expansion, with linear staining accentuation of glomerular and tubular basement membrane for Immunoglobulin G (IgG) and albumin on immunofluorescence. Conclusions: ING is a rare disease with a poor renal prognosis and wide diagnostic approach; we highlight the importance of analyzing every piece of detail together to reach a definitive diagnosis.
RESUMO Introdução: A glomerulosclerose nodular idiopática (GNI) tem um padrão histológico glomerular vasculopático. Apresentação do caso: Os autores apresentam o caso de uma mulher latino-americana, de 44 anos, fumante, com hipertensão e doença arterial periférica; com síndrome nefrótica por 2 semanas. Ela foi diagnosticada com GNI por biópsia renal percutânea, que mostrou expansão generalizada da matriz mesangial nodular, com acentuação de coloração linear na membrana basal glomerular e tubular para imunoglobulina G (IgG) e albumina à imunofluorescência. Conclusões: A GNI é uma doença rara, com mau prognóstico renal, e com necessidade de uma ampla abordagem diagnóstica. Demonstramos aqui a importância de se analisar todos os detalhes em conjunto para realizar um diagnóstico definitivo.
