Abstract

ABSTRACT:Group B streptococcus (Streptococcus agalactiae) is a common etiology of bacteremia among adults. Pyomyoma is a rare infectious complication of uterine leiomyomas. We report the case of a diabetic postmenopausal woman with a giant pyomyoma simulating an ovarian cancer. It was associated with S agalactiae endocarditis and deep venous thrombosis of the right external iliac and femoral veins. Treated initially with intravenous penicillin, amikacin, and anticoagulation, the patient later had abdominal hysterectomy with an uneventful recovery. We also review the cases of pyomyoma reported since 1945. Of 14 cases described (including ours), mortality was 21%. Endocarditis was never reported in association with pyomyoma. The presence of bacteremia and a leiomyoma should raise suspicion for this disease.
