[Extrathoracic forms of tuberculosis in Mahajanga hospitals (Madagascar)].

Pathological samples issued from patients suspected of extrapulmonary tuberculosis were examined in Laboratories of Mycobacteria and of Histopathology at the Androva Hospital in the University Hospital Centre of Mahajanga. A retrospective study was carried out from 1989 to 1993. During this period, 64 cases of extrapulmonary tuberculosis were recorded. Samples came from Androva Hospital, from Lutherian Hospital of Antanimalandy and from the Medical Centre of Mahabibo. The sex-ratio was of 1.28/1, mean age was 28 years old (extreme ages: 1-78 years old). The diagnosis was confirmed by bacteriological and/or histopathological examinations. Ganglial tuberculosis were the most frequent (53.1%), then digestive tract tuberculosis (20.2%) and anal fistula tuberculosis (14%). In front of chronic lesions, biopsies must be performed to obtain confirmation of diagnosis.
