| Summary points: | Three female patients, aged 15, 21, and 55 years, all present with non-nephrotic proteinuria associated with microscopic haematuria. The identification of collagenofibrotic glomerulopathy (CG), made through electronic microscopic scanning, is described; images provided. The authors discuss the first cases of CG reported from South America, and stress that importance of considering CG as an important differential diagnosis of cases of proteinuria. |
