A Case of Solitary Splenic Metastasis from Breast Cancer

Abstract

This paper reports the case of a 68-year-old woman with recurrence of spleen. She had undergone left partial resection with axillary lymph node dissection for breast cancer in 2005. Due to increasing levels of serum CA15-3 64 months after surgery, she underwent an abdominal CT scan, which detected no metastasis. FDG PET/CT revealed progression of the spleen tumor. Splenectomy was performed. The postoperative histological findings disclosed metastasis from breast cancer.
After surgery, we started chemotherapy, but peritoneal metastasis was detected 7 months later. Recurrence of breast cancer is often seen in the lung, liver, and bone. Solitary splenic metastasis is very rare ; therefore, this case is of interest. We report our experience with a review of the literature.
