Abstract
BACKGROUND
Gastrointestinal metastasis of breast cancer is rare, and clinicians may not have previously encountered this disease in clinical practice.
CASE SUMMARY
We report a patient with invasive lobular carcinoma of the breast who developed gastrointestinal metastasis two years after modified radical surgery. Mild elevation of carbohydrate antigen 15-3 was observed in the patient at an early stage; however, diagnosis and treatment were delayed due to non-specific clinical manifestations and no identifiable metastasis observed on imaging.
CONCLUSION
Clinicians should pay attention to gastrointestinal metastasis of breast cancer, especially invasive lobular carcinoma of the breast.
Core Tip: Gastrointestinal metastasis of breast cancer should be vigilant when tumor markers are elevated or when patients have digestive symptoms such as abdominal distention and defecation difficulties of unknown cause. Early detection, diagnosis, and treatment are needed to prevent disease progression and complications.
