Primary combined intra- and extra- abdominal actinomycosis. A case report.

Actinomycosis is an infrequent chronic progressive granulomatous and suppurative disease. This infection is caused by Actinomyces israelii, normally present in healthy individuals. We present a rare case of a combined intra- and extra- abdominal actinomycosis in a 50 year old female patient, with no underlying predisposing factors.
