Primary abdominal actinomycosis in a diabetic woman--an intractable disease.

Primary abdominal actinomycosis is very unusual. Only five previous cases have been reported in the English literature. We describe the case of a 57-year-old diabetic woman with primary abdominal actinomycosis, refractory to several antimicrobial regimens and surgical procedures. We conclude that primary abdominal actinomycosis in such a diabetic woman is an intractable disease.
