Beschreibung:
A case of visceral botryomycosis which arose in the left kidney of a 60‐year‐old woman is reported. This is the fifth reported case of renal botryomycosis which, in this patient, was mistaken clinically for a renal carcinoma. The lesion was composed of confluent abscesses containing ‘sulphur granule‐like’ lesions in which irregularly lobed aggregates of Gram‐negative organisms surrounded by an eosinophilic capsule were noted. Awareness of this unusual lesion is important because of its histopathological similarity to actinomycosis.
