[Cat-scratch disease. Presentation of 2 cases in a family with serologic follow-up and discussion of diagnostic methods].
Two cases are reported of cat scratch disease which we consider worth describing both because of their familial presentation (the involved patients were brothers) and the serologic follow-up performed after diagnosis, which showed significant increases in IgG antibody titers to Bartonella henselae in both patients, one on day 35 and the other on day 45 after diagnosis. Cat scratch disease is a rarely diagnosed condition in our environment and it is easily misdiagnosed with other regional lymphadenitis; hence, a serologic test revealing a seroconversion or a significant increase in serologic titers will be very useful, as well as the epidemiologic antecedent of cat exposure.
