[Cat-scratch disease. A report of 4 cases and a review of the literature].

Four cases of cat-scratch diseases are here reported and a review of the literature is made. The disease, apart from its typical presentation form as a usually self-limited regional lymph node enlargement, can occasionally spread and involve several organs systems. Indirect immunofluorescence serological tests have been of help for its diagnosis and should be included among the diagnostic criteria for the disease. In particular cases, nuclear magnetic resonance can be useful to suggests the diagnosis.
