Being a rare entity, it is often missed, or the diagnosis is delayed, since the definitive diagnosis requires special laboratory tests. Kidneys, the walls of blood vessels, and bones are the major sites for crystal deposition. We report the autopsy findings of a 4-year-old girl who presented with end-stage renal disease in which the clinical presentation was consistent with primary hyperoxaluria Type I. The case is unusual, as there was extensive crystal deposition throughout the body, including in tissues that are rarely involved, such as ovaries, fallopian tubes, uterus, thymus, salivary glands, pancreas, and bladder. © 2009 Society for Pediatric Pathology.EnglishCalcium OxalateChild, PreschoolFatal OutcomeFemaleHumansHyperoxaluria, PrimaryKidneyKidney Failure, ChronicMicroscopy, Polarizationcalciumcreatinineabdominal painanamnesisarticleautopsybladdercalcium blood levelcase reportchildcreatinine blood levelechocardiographyfemaleheart auscultationheart left ventricle hypertrophyhospital admissionhumanhuman tissuekidney calcificationkidney failureliver biopsyliver function testlung artery pressurelung edemaovaryoxalosis 1pancreaspericardial effusionperitoneal dialysisperitonitisphysical examinationpreschool childpriority journalpulmonary hypertensionsalivary glandsystolic heart murmurthymusultrasounduterine tubeuterusX ray analysisArticle10.2350/07-06-0293.1
