[Actinomycosis of the abdominal wall. Report of a case]

Actinomycosis is a chronic infectious disease, caused by an anaerobic gram positive microorganism, the actinomyces israelii. It grows by continuity toward adjacent organs, with formation of dense masses of woody tissue, producing draining abscesses and fistulae. General symptoms of this disease are fever, chills, in association with symptoms proper of each localization. The diagnosis is made when the "sulphur granules" that are characteristic of the pus of actinomycosis are found.
