title: [Actinomycosis of the kidney: a case report].
abstract: Actinomycosis is a rare infection mainly of the head and neck region (cervicofacial actinomycosis). The cause of this infection is bacterial invasion of the host's mucosal barrier with consecutive infiltration of the surrounding tissues. The treatment of choice after diagnosis is a prolonged course of high-dose antibiotics. The presence of abdominal actinomycosis is at a maximum of 25%, whereas renal involvement appears only sporadically. Aggravating causes for early diagnosis are the appearance of abscesses, fistulae and a debilitating illness resembling carcinoma and leading to surgery as the treatment of choice. Renal actinomycosis is a diagnostic challenge because it is included in the differential diagnosis of renal masses with coexisting B-symptoms. The suspicion requires surgical treatment--nephrectomy. We report on a patient who was transferred to our department for nephrectomy because of radiologically diagnosed renal and perirenal abscesses. The histological result showed renal actinomycosis.
