[Extra-abdominal desmoid fibroma and pulmonary metastases. (New Caledonia)].
A 22 years old Melanesian patient had a tumor in the anterior and external side of the left leg. Three times, this tumor had a surgical treatment, by resection, then an amputation of the leg. Always, its histological aspect was agreeing with a desmoid fibroma. After an evolution of 23 months time, metastases appeared in the lungs. Most of the authors don't agree the existence of metastases in these tumors. Four observations were reported in the literature, including one in 1989. They emphasize the difficulties of the histological diagnosis of these tumors. The metastases seems to be an argument in the evolution, which incites to modify the initial diagnosis as a fibrosarcoma in spite of the lack of obvious histological malignancy.

[Infectious diarrhea in African acquired immunodepression syndrome (AIDS). Apropos of 100 patients studied in Bujumbura (Burundi)].
The authors carried out a prospective survey on 100 cases of AIDS in order to find out the different etiologies of infections diarrhoea in terms of frequency and diagnosis behaviour. 84 out of 100 patients got diarrhoea. All 100 patients had their stools examined, 78 underwent high digestive fibroscopy with irrigation and aspiration of duodenal liquid (IADL), 40 duodenal biopsies. 98 infecting agents were revealed in stool exams, 50 in IADL, 7 at the occasion of histopathological exam of duodenal biopsies. All together, stool exams and IADL gave evidence that Isospora belli and Cryptosporidium are the opportunistic infecting agents most often revealed (16.2 and 13.1 p.c., respectively). The role of yeasts in diarrhoea is not evident, but esophageal candidosis is the most frequent opportunistic digestive infection (48 p.c.). Anguillula is the only intestinal worm appearing to play a role: the role of bacteria and viruses cannot be evaluated precisely, but histopathological study revealed neither an atypical mycobacteriosis nor a virus disease (herpes, cytomegalovirus). If diagnosis appears to be still difficult in 1989 when confronted with AIDS and diarrhoea, it seems highly advisable to examine the stools, to perform high digestive fibroscopy with IADL and biopsies. On the other hand, indications for colonoscopy appear to be restricted.
[Current strategies in the campaign against Plasmodium falciparum malaria in an area resistant to 4-aminoquinolines].
Confronted with the extension of chemoresistance of P. falciparum and the gradual renunciation of the fight against the vectors, it is important nowadays to manage better the means of fighting in the zones where chloroquine resistance exists. If preventive treatment of chills by 4-aminoquinolines is still able to realize prevention of mortality, treatment of all confirmed chills by P. falciparum has to combine sulfadoxine-pyrimethamine with quinine or amodiaquine.
[Principle aspects of acquired immunodeficiency syndrome (AIDS) in adults in Burundi].
The authors describe their experience of the infection by the virus of the human immunodeficiency HIV-1 in Burundi. The acquired immunodeficiency syndrome was brought to light in 1983 by the emergence of cryptococcal meningitis, Kaposi's sarcomas, disseminated candidiasis. 109 cases of infection by the virus of the human immunodeficiency (HIV) AIDS related complex, or acquired immunodeficiency syndromes, were observed in 8 months and are related in this paper. The authors elucidate the spread and amplify the role played by lorry drivers. The frequency of recent case history: tuberculosis, zona, sexually transmitted diseases (41%). Clinical manifestations have been studied according to their clinical stage: 28 patients are AIDS related complex (25%), 81 are acquired immunodeficiency syndrome. One have to notice the frequency of tuberculosis at the stage of acquired immunodeficiency syndrome, of digestive parasitoses, not only coccidiosis, but also strongyloidiasis and colonic amoebiasis, cryptococcal meningitis, and encephalopathies caused by the virus of human immunodeficiency (HIV) at the period of AIDS. Lethal evolution is fast: 28 out of the 81 AIDS were observed up to their end, occurring in less than 60 days, as an average. Lastly, numerous opportunistic infections cannot be diagnosed because the lack of technical facilities.
[A new case of African histoplasmosis with multiple localizations in the bones].
Bone localizations of histoplasmosis at H. duboisii are frequent (1 out of 3). Multiple localizations, far less frequent but not exceptional, are immediately diagnosed at the occasion of a systematic X-Ray check-up, or later, as presented in this case. Multiple localizations give evidence of the septicaemic diffusion of the pathogenic agent.

[Genitourinary bilharzioma. Isolated cases of vesical bilharzioma and epididymal bilharzioma].
The authors report on two isolated cases of bilharzioma: one vesical revealed by an hematuria and one epididymal constituting an intrascrotal mass. Clinical signs did not oriented toward these diagnosis and biology was helpless. Serodiagnosis by hemagglutination was negative, but immunofluorescence was more reliable. On the contrary both tumors were detected by echotomography of which the efficiency is determinant for the diagnosis and must be underlined. Only anatomopathology was able to confirm the diagnosis of tumor. As a matter of course, surgical exploration and excision are necessary in these types of tumors with negative biology. In both cases, effects were isolated. In one patient, infestation was old and already treated; in the second one, infestation was probably light. The authors recall also bilharzioma physiopathology. Frequency of vesical bilharzioma is about 20% of genito-urinary schistosomiasis while epididymal bilharzioma reaches only 0.29 to 4.8%. Direct line between bilharzioma and cancer is likely but controversial, schistosomiasis beeing a true irritative agent.
