title: Adenocarcinoma of the breast metastatic to benign ovarian fibroma.
abstract: An elderly woman presenting with a perforated benign gastric peptic ulcer was found to have widespread dissemination of breast carcinoma. Several small discrete metastases were present within a large benign ovarian fibroma. The rare phenomenon of tumor-to-tumor metastasis is discussed in the context of ovarian pathology.
