Metastatic Breast Lobular Carcinoma to Unusual Sites: A Report of Three Cases and Review of Literature

Hossameldin Abdallah, Amira Elwy, Aya Alsayed, Ahmed Rabea, Nesreen Magdy


Invasive lobular carcinoma of the breast is the second most common type of invasive breast carcinoma. Invasive lobular carcinoma has an unusual pattern of metastases, which poses a diagnostic challenge for both clinicians and pathologists. We herein present three cases of breast invasive lobular carcinoma presented with metastasis to unusual sites, namely, uterus, colon and stomach. We recommend a higher index of suspicion in any case with breast cancer developing gastrointestinal tract or genital tract symptoms.
