A Rare Case of Fallopian Tube Metastasis Presenting as a Solitary Breast Mass.

Abstract

Metastases to the breast from a nonmammary primary are rare. Primary fallopian tube carcinoma is one of the rarest malignancies of the female genital tract. Therefore, breast metastases from primary fallopian tube carcinoma are considered extremely rare. In this article, we shared the case of serous carcinoma of fallopian tube with metastasis to an intramammary lymph node, presenting as a solitary breast mass. On initial staging 18 F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography for this patient with serous carcinoma of fallopian tube, a solitary FDG avid breast mass was found, along with FDG avid multistation nodes. The breast mass was evaluated with diagnostic mammogram and ultrasound and eventually biopsy of this mass revealed metastatic lymph node from carcinoma of fallopian tube origin.
