[Lymph node tuberculosis in France in non-immunosuppressed adults: current pathology]

Lymph node tuberculosis is more frequent in Africa or in HIV-infected patients.

We review results that were obtained in 18 patients with lymph node tuberculosis but without infection by HIV. Eight French native patients (mean age: 69 years) and ten African patients (mean age: 32.5 years) were included into the study.

Of the 18 patients, 14 had exclusively hematopoietic localizations, two with medullar involvement and two with either liver or spleen involvement. Normal erythrocyte sedimentation rate was found in two out of 18 cases and normal C-reactive protein levels in seven out of 17 cases. Lymph node biopsy revealed lesions typically associated with tuberculosis in 12 out of 14 patients, two of them had no necrosis. Inflammatory syndrome was inconstant, tuberculin test sometimes negative. A favorable outcome was seen in all cases after 6, 12 or 18 months of treatment, depending on clinical appreciation.

Tuberculous lymphadenopathy in non-HIV-infected patients may occur without inflammatory syndrome, with sometimes negative tuberculin test and without lymph node necrosis.
