We analyzed the clinical background of 63 patients with serologically confirmed cat scratch disease (CSD), Age range of the patients was 0 to 83 years old and mean age was 35.0 years old. Seasonal patterns of cases was observed. A number of patients with CSD was increased during the summer and fall. The peak incidence of CSD occurred in October. Infection followed direct cat or dog contact. Cat contact occurred in 61 cases (96.8%) and dog contact in 2 cases (3.2%). A specific contact with kittens occurred in 39 cases (61.9%). About 49.2% of patients had a cat scratch, 3.2% had a cat bite, 3.2% had a cat flea bite, 41.2% had no history of animal bite. The papule of inoculation site were seen in 27 cases (42.9%) of CSD. The upper extremities were the most likely locations for scratches. Sixty cases (95.2%) of CSD developed lymphadenopathy, 51.7% of the involved nodes were in the axillary, 31.7% were in the inguinal, 21.7% were in the cervical, 16.7% were in the elbow. The mean incubation period of patients with CSD was 18.9 days. The mean duration of lymphadenopathy after the treatment of antibiotics was 44.2 days. The mean value of white blood cell counts was 8130/microL. The mean value of C-reactive protein level was 2.83 mg/dL.
