RESUMEN
Ovarian metastatic breast cancer is infrequent and usually is originating from lobular carcinomas. It was found that the risk of developing an ovarian neoplasm is approximately doubled in women with a history of breast cancer. The finding of an adnexal mass in these patients involves a particular concern and requires a study. We report a case of a 67-year-old female diagnosed of an infiltrating lobular breast carcinoma. It is done lumpectomy and an axillary dissection of lymph nodes resulting 2 of 13 lymph nodes positives. She was treated with chemotherapy and hormone treatment staying the disease in remission for years. After she was admitted with malignant pleural effusion and pathological costal fracture. The ultrasound shows an increase of size of annexes and a CA125 and CA15.3 increased in the analysis. Bilateral oophorectomy was performed. The pathology was consistent with lobular breast carcinoma. Subsequently another income was required because of disease progression. Currently after almost two years since the adnexectomy, is in close monitoring by medical oncologists. Although the diagnosis of an adnexal mass in a woman who has had breast cancer is usually a benign finding, the risk in these women to develop a malignant ovarian pathology is increased compared to the general population. Therefore, although the patient remains asymptomatic, it is important an abdominopelvic exploration from time to time. If the ultrasound image of the adnexal mass is suspect, the CA125 is increased, or estrogen receptors are negatives in the original breast tumor, should be performed surgical evaluation.
