[Pleuro- XXXX . Report of 4 cases].

@entity1 @entity5850 @entity358 @entity153
Four cases of @entity358 are reported. Two cases (1978, 1979) were diagnosed on microscopic examination of lung parenchyma excised on suspicion of @entity153 . The third case was diagnosed retrospectively by reexamining the slides of a @entity1 operated on in 1965, who presented with a similar history and chest X-ray. The fourth was diagnosed at autopsy in a @entity1 who committed suicide. @entity5850 is a rare disease which affects the lung in 15--20% of cases. Despite its name, @entity5850 is not due to a fungus but to an anaerobic gram-positive bacillus. The germ is a saprophyte of the @entity1 digestive tract and is very sensitive to penicillins. It may become pathogenic in a compromised host and usually produces cervico-facial lesions which develop by continuity from mouth mucosa. Abdominal or, more rarely, @entity358 are due to ingestion or inhalation of infected material. Chest X-ray appearance of @entity358 mimics that of @entity153 . Actinomyces culture is difficult, and diagnosis is often based on microscopic examination of the surgical specimen only. Antibiotic therapy is a mandatory complement to surgical treatment.
