[Anergic miliary tuberculosis, with principally splenic localization simulating hemolymphopathy. Report of 4 cases]. / Tubercolosi miliare anergica a principale localizzazione splenica simulante una emolinfopatia. Descrizione di 4 casi.

Four cases of disseminated tuberculosis with prevailing spleen involvement and lack of tuberculin reactivity are described. The atypical clinical picture justified, at the beginning of the disease, the suspect of a lymphoreticular disorder (malignant lymphoma in 3 cases) or of a pulmonary hemosiderosis (in 1 case). The splenectomy and the following anti-tubercular chemotherapy were fully successful in all 4 patients and the skin reactivity was restored. The Authors discuss the pathogenesis of the observed features and the differential diagnosis of the cases of tuberculosis with only extrapulmonary involvement. These cases represent today about 1/6 of the patients with postprimary tuberculosis.
