title: Botryomycosis of the liver.
abstract: A case of visceral botryomycosis of the liver in a 50-year-old man is reported. The clinical diagnosis was hepatocellular carcinoma. Pathological examination of the surgically resected specimen demonstrated microabscesses containing gram- positive microorganisms with surrounding fibrosis replacing liver parenchyma. An immune deficiency state was not demonstrated. Recognition of this condition is important because of its clinical confusion with malignancy and its histological similarity to actinomycosis, nocardia, and eumycotic infections.
