[Hepatic actinomycosis--pseudotumoral form].

Hepatic actinomycosis is a pretty rare anatomo-clinical entity that often induces a wrong pre-operative diagnosis. By presenting a case of hepatic actinomycosis, apparently primitive and diagnosed pre-operatively as a neoplastic lesion, the authors discuss the diagnosis and treatment of this disease, mentioning that in the solid, tumoral forms, the hepatic resection is necessary. The authors consider that the post-operative addition of antibiotherapy (mega doses of penicillin) is useful for the eradication of inflammatory residual hepatic parenchyma as well as for the cicatrisation of the parietal fistulae.
