Introduction: Phyllodes tumor of the breast is a rare cause of breast cancer, accounting for less than 0.5% of breast cancers. These tumors are classified as benign, borderline, or malignant, with malignant tumors compromising nearly 25% of cases. Metastases occur in 20% of malignant tumors, lungs, bones, liver and brain being the frequent sites of metastases.

Presentation of case: We present a case of a metastatic phyllodes tumor to the small bowel causing jejunal intussusception, symptomatic anemia, and small bowel obstruction.

Discussion: Patients with phyllodes tumor of the breast can develop disease recurrence even years after initial treatment. Phyllodes tumor metastasizing to the small bowel is extremely rare, with only three known previously described case reports in the literature.

Conclusion: High risk patients, with a past medical history of phyllodes breast cancer, should be monitored closely. Even years after breast cancer treatment, these patients may present with gastrointestinal complaints such as obstruction or bleeding, and therefore metastatic disease to the small bowel should be considered on the differential with subsequent abdominal imaging obtained.
