Insights
Kimura disease, a rare inflammatory condition, can present atypically in Caucasian men with nephrotic syndrome. Early diagnosis and treatment with steroids, endoxan, and MMF are crucial for successful outcomes.
Area of Science:
- Nephrology
- Immunology
- Pathology
Background:
- Kimura disease (KD) is a rare chronic inflammatory disorder characterized by angiolymphatic proliferation.
- KD typically affects young Asian men but is uncommon in other demographics.
- Nephrotic syndrome is a frequent comorbidity of Kimura disease.
Observation:
- This report details an atypical case of Kimura disease in a middle-aged Caucasian male.
- The patient presented with steroid-responsive early membranous glomerulonephritis.
- This presentation deviates from the typical demographic and clinical profile of KD.
Findings:
- Kimura disease can manifest atypically in Caucasian individuals, presenting as secondary steroid-responsive nephrotic syndrome.
- Treatment with corticosteroids, cyclophosphamide (endoxan), and mycophenolate mofetil (MMF) demonstrated safety and efficacy.
- Diagnostic challenges exist due to the rarity and atypical presentations of KD, potentially leading to delayed or incorrect evaluations.
Implications:
- Highlights the importance of considering Kimura disease in Caucasian patients with unexplained nephrotic syndrome.
- Suggests that established immunosuppressive therapies are effective for atypical KD presentations.
- Emphasizes the need for increased awareness among clinicians to avoid diagnostic delays and unnecessary procedures for Kimura disease.
Abstract:
Kimura disease (KD) is a chronic inflammatory disorder with angiolymphatic proliferation, usually affecting young men of Asian race but is rare in other races. The etiology of KD is still unknown. It is often accompanied by nephrotic syndrome. Herein, we present an atypical manifestation of Kimura disease occurring in a Caucasian man with steroid-responsive early membranous glomerulonephritis. Kimura disease can present atypically in a middle-aged Caucasian man with secondary steroid-responsive nephrotic syndrome. Steroid, endoxan, and MMF can be used safely and successfully in such situation. The diagnosis of KD can be difficult and misleading, and patients with this disease are often evaluated using avoidable procedures by just not being aware of KD.

Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
