Summary
Cat-scratch disease (CSD) can affect abdominal organs, not just lymph nodes. Early clinical suspicion and noninvasive diagnosis of CSD are key for better patient outcomes.
Area of Science:
- Infectious Diseases
- Pathology
- Immunology
Background:
- Cat-scratch disease (CSD) is typically characterized by lymphadenopathy.
- Atypical presentations of CSD can pose diagnostic challenges.
Observation:
- Three cases of unsuspected CSD diagnosed via visceral organ involvement are presented.
- CSD bacilli were identified in splenic granulomas in a child and an adult with AIDS-related complex.
- Hepatic granulomas with suppuration were observed in one adult patient.
Findings:
- Granulomatous inflammation with suppuration in visceral organs mirrors findings in lymph nodes.
- Splenitis and granulomatous hepatitis were noted in two cases.
- The CSD bacillus was confirmed in hepatic granulomas in the third case.
Implications:
- Broadening clinical awareness of CSD's spectrum can prevent unnecessary interventions.
- Noninvasive diagnostic approaches are preferred for CSD.
- Prompt diagnosis of CSD avoids prolonged hospitalization and invasive treatments.
