Gastric metastases from invasive lobular carcinoma of the breast: case report and literature review

This case highlights the diagnostic challenge of gastric metastases from ILC, which may present many years after the initial diagnosis. Definitive diagnosis requires immunohistochemistry to distinguish metastatic breast carcinoma from primary gastric carcinoma. Systemic therapy remains the mainstay of treatment, while surgical intervention should be reserved for selected palliative indications. Increased awareness of this rare manifestation is crucial to avoid misdiagnosis and optimize multidisciplinary management.
