Beyond the Usual Suspects: Bilateral Postauricular Swelling in a Child

Area of Science:

• Pediatric Pathology
• Diagnostic Cytology

Background:

• Kimura disease is an uncommon condition, particularly in children under 10 years old.
• Early and accurate diagnosis is crucial for effective management.

Purpose of the Study:

• To highlight the role of fine needle aspiration cytology (FNAC) in the initial diagnosis of Kimura disease in pediatric cases.
• To emphasize the utility of specific blood investigations in supporting the cytological findings.

Main Methods:

• Review of pediatric cases with suspected Kimura disease.
• Analysis of cytological features obtained through FNAC.
• Correlation of cytological findings with blood investigations, including eosinophil counts and serum IgE levels.

Main Results:

• FNAC provided suggestive features aiding in the preliminary diagnosis of Kimura disease.
• Eosinophilia and elevated serum IgE levels were consistently observed in confirmed cases, corroborating the cytological suspicion.

Conclusions:

• FNAC is a valuable, minimally invasive tool for identifying suggestive features of Kimura disease in children.
• Combined with hematological findings like eosinophilia and elevated IgE, FNAC can effectively guide towards a diagnosis of Kimura disease in pediatric patients.
