Idiopathic retroperitoneal fibrosis presented as an abdominal mass and nephrotic syndrome
1Department of Internal Medicine and Pathology, Seoul National University-Hospital, Korea.
Abstract:
We present a 30-year-old male patient who was initially diagnosed as minimal change nephrotic syndrome, 5 years later, the patient developed a localized form of idiopathic retroperitoneal fibrosis (IRF). An elevated ESR and concomitant nephrotic syndrome in the patient suggested the immunologic nature of IRF, IRF has been reported in association with collagen diseases and rarely with proliferative and nonproliferative glomerulopathies. To our knowledge, the association between minimal change lesion (MC) and IRF has not been reported. Furthermore, the fact that IRF presented itself as an abdominal mass and lacked systemic symptoms was also unusual.
Insights
A rare case links minimal change nephrotic syndrome to idiopathic retroperitoneal fibrosis (IRF). This association, previously unreported, highlights potential immunologic connections in kidney and fibrotic diseases.
Area of Science:
- Nephrology
- Immunology
- Pathology
Background:
- Idiopathic retroperitoneal fibrosis (IRF) is a rare condition characterized by excessive fibrous tissue growth in the retroperitoneum.
- IRF has been associated with autoimmune diseases and certain kidney disorders, but its specific triggers remain under investigation.
- Minimal change nephrotic syndrome (MCNS) is a common cause of nephrotic syndrome in children, typically responding well to corticosteroids.
Observation:
- A 30-year-old male initially diagnosed with MCNS later developed a localized form of IRF.
- The patient presented with an abdominal mass, an unusual manifestation of IRF, and lacked systemic symptoms.
- Elevated erythrocyte sedimentation rate (ESR) and persistent nephrotic syndrome suggested an underlying immunologic process contributing to IRF.
Findings:
- This case represents the first reported association between minimal change lesion (MC) and idiopathic retroperitoneal fibrosis (IRF).
- The findings suggest a potential, previously unrecognized immunologic link between MCNS and the development of IRF.
- The localized presentation of IRF as an abdominal mass, without systemic symptoms, is atypical.
Implications:
- This case expands the known clinical spectrum of IRF and its potential associations.
- Further research is warranted to elucidate the immunopathogenesis linking MCNS and IRF.
- Understanding this association may lead to novel diagnostic or therapeutic strategies for both conditions.
