Summary
Gastrointestinal metastases from lobular breast cancer are rare but can cause chronic diarrhea. This case highlights the importance of considering breast cancer recurrence in patients with persistent gastrointestinal symptoms.
Area of Science:
- Oncology
- Gastroenterology
- Pathology
Background:
- Lobular breast carcinoma is a common malignancy.
- Gastrointestinal metastases from breast cancer are infrequent.
- Persistent gastrointestinal symptoms warrant thorough investigation.
Purpose of the Study:
- To report a rare case of lobular breast carcinoma metastasizing to the colon.
- To emphasize the diagnostic challenges and importance of considering metastatic disease in patients with a history of breast cancer.
Main Methods:
- Case report of a 70-year-old woman with a history of lobular breast cancer.
- Clinical examination and laboratory tests were performed.
- Colonoscopy with biopsies of the ascending, transverse, and descending colon was conducted.
Main Results:
- The patient presented with 3 years of chronic diarrhea.
- Colonoscopy revealed diffuse mild erythema and a decreased vascular pattern.
- Biopsies confirmed metastases of lobular breast carcinoma in the colon.
Conclusions:
- Gastrointestinal metastases from lobular breast cancer, though rare, should be considered in patients with a history of breast cancer and unexplained gastrointestinal symptoms.
- Further diagnostic efforts are crucial for timely diagnosis and management.

Diarrhea, a condition marked by frequent loose or watery bowel movements, can be triggered by multiple factors such as viral or bacterial infections, food intolerances, anxiety, medications, and digestive disorders. Symptoms may include abdominal pain, bloating, nausea, and cramping. Severe or prolonged diarrhea can lead to complications like electrolyte imbalances, malnutrition, and dehydration if left untreated.
