Cat scratch disease: clinical considerations for the pediatric dentist

Area of Science:

• Infectious Diseases
• Pediatric Medicine
• Bacteriology

Background:

• Cat scratch disease (CSD) is a common bacterial infection caused by Bartonella henselae, typically transmitted by cats.
• It usually presents as self-limited chronic lymphadenopathy, primarily affecting cervical and submandibular lymph nodes.
• Accurate diagnosis can be challenging due to its varied presentations, mimicking other conditions.

Observation:

• A unique case of a 6-year-old male with CSD following close contact with a domestic dog is presented.
• The patient developed CSD with progression to suppuration, indicating a severe presentation.
• Initial antibiotic treatment proved unsuccessful, necessitating surgical intervention.

Findings:

• This case highlights a rare transmission route of Bartonella henselae via dogs.
• The suppurative progression of CSD underscores the importance of vigilant monitoring and reassessment of treatment.
• The pediatric dental office may encounter CSD cases, emphasizing the need for broad diagnostic awareness.

Implications:

• Clinicians should consider CSD in pediatric patients with lymphadenopathy, even with atypical exposure histories like dog contact.
• Prompt diagnosis and appropriate management, potentially including surgical drainage for suppurative cases, are vital.
• Increased awareness among healthcare providers, including dentists, can prevent diagnostic delays and unnecessary interventions for CSD.
