Data Sheet 1_Case Report: IgG4-rich tubulointerstitial inflammation in MPO-ANCA-associated

A case report PDF details an 81-year-old female patient diagnosed with overlapping anti-neutrophil cytoplasmic antibody-associated glomerulonephritis and IgG4-related tubulointerstitial nephritis. The document includes a review of previously reported cases, illustrating diagnostic complexities in autoimmune renal disease. The file was authored by Songlin Qiu and last updated on May 12, 2026.

Use Cases

• Study the co-occurrence of pauci-immune crescentic glomerulonephritis and IgG4-positive plasma cell infiltration based on the described case.
• Review diagnostic criteria for differentiating IgG4-related disease from ANCA-associated vasculitis based on the clinicopathologic correlation discussed.
• Analyze histologic features like storiform fibrosis and dense plasma cell infiltrates in renal biopsy samples as described in the report.

Strengths

• Includes a comprehensive review of all previously reported cases of this overlap syndrome.
• Provides detailed clinicopathologic correlation from a confirmed renal biopsy.

Limitations

• The dataset is a single PDF file (133.3 KB), representing a limited scope of one case report.
• Row count and column-level documentation are absent; data structure must be inferred from the text.
• Description metadata is limited; actual data quality requires manual inspection after download.
