Abstract:
Cat-scratch disease is usually a self-limited illness characterized by regional lymphadenopathy and a skin inoculation lesion. These findings generally resolve spontaneously over a period of several weeks or months. The discovery of the causative organism, an intracellular gram-negative rod and the recognition of severe systemic courses in immuno-compromised patients have renewed the interest in this disease. We report a prolonged clinical course with lymph node suppuration in an immunocompetent patient. The diagnosis was confirmed by the detection of the organism in Warthin-Starry silver stained lymph node biopsy.
Insights
Cat-scratch disease typically resolves quickly. However, this case shows a prolonged, severe presentation with lymph node suppuration in an immunocompetent individual, confirmed by biopsy.
Area of Science:
- Infectious Diseases
- Microbiology
- Immunology
Background:
- Cat-scratch disease (CSD) is typically a self-limiting illness.
- Characterized by regional lymphadenopathy and a skin inoculation lesion.
- Severe systemic courses are recognized in immunocompromised patients, renewing interest in CSD.
Observation:
- This study reports a case of CSD with an unusual clinical course.
- The patient was immunocompetent but experienced prolonged symptoms.
- Lymph node suppuration was a prominent feature.
Findings:
- The diagnosis of CSD was confirmed via Warthin-Starry silver stain of a lymph node biopsy.
- The causative organism, an intracellular gram-negative rod, was detected.
- The prolonged clinical course and suppuration occurred in an immunocompetent host.
Implications:
- This case highlights that CSD can present with prolonged and severe symptoms even in immunocompetent individuals.
- It underscores the importance of considering CSD in the differential diagnosis of persistent lymphadenopathy.
- Further research may elucidate factors contributing to severe CSD presentations in diverse patient populations.
