title: [Problems of differential diagnosis of orbital granulation].
abstract: Three cases of orbital tumours caused by granulation are presented. They required advanced differential diagnosis between sarcoidosis, tuberculosis and Wegener's granulomatosis. Each of the patients had an orbitotomy according to Krönlein performed. All were cured. Because of vague results of the histopathological examinations, immunological tests such as: indirect immunofluorescence, direct immunofluorescence and immunodiffusion were performed and cANCA levels were evaluated in order to establish the final diagnoses.
