Summary
Cat scratch disease, caused by Bartonella henselae, can rarely affect the parotid gland, mimicking tumors. Early diagnosis with serology and imaging is crucial for effective treatment with antibiotics like doxycycline.
Area of Science:
- Infectious Diseases
- Otolaryngology
- Medical Diagnostics
Background:
- Cat scratch disease (CSD) is a bacterial infection caused by Bartonella henselae.
- It is a common cause of chronic adenopathy in pediatric and young adult populations.
Observation:
- A 36-year-old female presented with unilateral parotid swelling, initially suspected to be a pleomorphic adenoma.
- Diagnostic workup included ultrasonography, MRI, fine-needle aspiration, and Bartonella henselae serology.
Findings:
- The patient was diagnosed with parotid gland cat scratch disease.
- Treatment with doxycycline resulted in clinical improvement within 15 days.
Implications:
- Parotid localization of CSD is uncommon, posing diagnostic challenges due to potential confusion with neoplastic or other lymphatic conditions.
- Timely and accurate diagnosis, supported by specific serological tests and imaging, can prevent unnecessary surgical interventions.
- This case highlights the importance of considering infectious etiologies in parotid swelling, even in the absence of typical CSD symptoms.
