A 35-year old male farmer, on injury to the index finger with consequent axillary lymphadenitis on the right, with a mild overall inflammatory alteration (mild febrile state; BSR, CRP, leucocytosis - all increased moderately) was treated as an outpatient (cefadroxil) and then during hospitalization (cefadroxil + ciprofloxacin). After being a month markedly worse off, admitted to the department of hematology where within the framework of continuing differential diagnostics of a lymphadenoid syndrome, on the basis of anamnestic data (cat on the farm) and clinical picture, doxycycline was administered and an extirpation of the lymph node packet in the given localization. Histology was in line with cat-scratch disease and its etiology was subsequently confirmed by serology of paired blood serum samples focused on Bartonella henselae. The clinical state of the patient markedly improved under therapy; a month after its beginning he felt well subjectively, the above-mentioned markers of a systemic inflammation returned to normal completely.
