[Atypical cat-scratch disease: a case report of splenic granulomatosis]

Generally cat-scratch disease is a benign inflammatory adenopathy. The Authors describe an atypical form of this disease, characterized by persistent fever and splenic granulomatosis requiring a diagnostic and therapeutic prolonged effort. They point out the important role of new immuno-fluorescent techniques to exactly identify the bacterium--Bartonella henselae--causing cat-scratch disease and suggest to include cat-scratch disease among the causes of unknown origin fever.
