title: A metastasis of an adenocarcinoma in a BRCA1 mutation carrier, a diagnostic problem not solved by morphology alone.
abstract: To increase awareness of the possible coexistence of an ovarian and breast carcinoma in a BRCA1 mutation carrier, we describe a patient with primary ovarian cancer who developed distant metastases after 3 years and again after 6 years. Surprisingly, at that time an occult breast carcinoma was identified to be the origin of the 2 metastatic locations as confirmed by molecular analysis. Eventually the patient could be treated accordingly.
