[Two patients with cat scratch disease].

BACKGROUND

Cat scratch disease (CSD) is caused by Bartonella henselae infection. CSD is usually characterized by self-limiting regional lymphadenopathy. However, sometimes CSD presents as a disseminated disease with multiple organ involvement.

CASE DESCRIPTIONS

We describe two patients with CSD. Patient A, an 18-year old woman, was referred because of fatigue, a subfebrile temperature and axillary lymphadenopathy. Patient B, a 50-year old man, visited the emergency ward with fever, back pain and painful inguinal lymphadenopathy. MRI showed osteitis of vertebrae and hepatic abcesses. In both patients symptoms started after being scratched by a cat and both were tested positive for infection with Bartonella henselae. Patient B was treated with antibiotics. Both patients made a full recovery.

CONCLUSION

Recent contact with a cat in a patient with unexplained fever and lymphadenopathy raises the possibility of CSD. Diagnosis can be confirmed by serologic testing, histopathology or PCR. Antimicrobial treatment must be considered in all cases.
