Sixty two patients fulfilling the definition established by the Centers for Disease Control in 1982 for persistent lymphadenopathy syndrome, thought to be related to the human immunodeficiency virus (HIV) infection, were selected at the Butare university hospital, in Rwanda, between 1987 and 1988. Forty-five (73 %) of them were indeed seropositive. Fifteen patients of sixty two (24 %) presented unexpectedly evidence of tuberculous adenitis on biopsy.
Three of them, found HIV-1 seronegative, showed a classical follicular adenitis, whereas the twelve other seropositive patients presented unusual histologic features, consisting of more or less immature tuberculoid granulomas with an abundant caseating and often granular necrosis, containing acid fast bacilli. Numerous blood vessels and abundant plasmacytosis were found in non-necrotic areas. Semi-quantitative evaluation of the granulomatous reaction components provided a histological spectrum probably related to the degree of impairment of the cellular immune response, which could be of prognostic significance.
In areas where populations are exposed to both HIV and M. tuberculosis, it appears that lymph node biopsy with mycobacterial culture should be recommended in order to detect occult tuberculosis among HIV-seropositive persons, allowing accurate medical care and adequate public health surveillance.
