Cat Scratch Disease - The Inconspicuous Cause of Cervical Lymphadenopathy

Area of Science:

• Infectious Diseases
• Bacteriology
• Pediatrics

Background:

• Cat scratch disease (CSD), or subacute regional lymphadenitis, is a bacterial infection transmitted by cats.
• Caused primarily by Bartonella henselae, CSD presents as lymphadenopathy near the inoculation site.
• CSD can mimic other conditions, complicating accurate diagnosis.

Observation:

• A 12-year-old girl presented with submandibular lymph node swelling.
• The patient had recent close contact with a pet cat.
• The clinical presentation suggested a potential diagnosis of CSD.

Findings:

• Bacterial infection, specifically Bartonella henselae, was identified as the cause of the patient's symptoms.
• The swelling of submandibular lymph nodes was directly linked to cat scratch disease.
• The case illustrates CSD in a pediatric patient with specific lymph node involvement.

Implications:

• Early recognition of CSD is crucial, especially in pediatric cases presenting with lymphadenopathy.
• Differential diagnosis for submandibular swelling should include infectious causes like CSD.
• Understanding transmission routes, such as contact with pets, aids in diagnosing and managing CSD.
