The Stomach: An Uncommon Site for Metastatic Breast Cancer

Abstract

Invasive Lobular Carcinoma (ILC) is distinct from Invasive Ductal Carcinoma (IDC) in morphology and biology, with more advanced disease at presentation and a different pattern of metastatic spread. We present a case of metastatic ILC that presented with symptomatic anemia secondary to gastric metastasis. Metastasis of breast cancer to the gastrointestinal tract is uncommon but can present as distant recurrence years after the primary breast lesion is treated. A high index of suspicion should be present when a patient with invasive lobular breast cancer presents with unexplained anemia as this will guide subsequent investigations and treatment.
