Colonic metastasis of invasive lobular breast carcinoma 14 years after the initial diagnosis

Abstract

A 57-year-old woman with a history of lobular carcinoma of the left breast (stage I, T1b-N0-M0, HER2/neu-negative; estrogen and progesterone receptor-positive) diagnosed 14 years ago, treated with modified radical mastectomy and tamoxifen, followed by surveillance for 5 years. She recently returned due to dysphagia, chest pain, hyporexia, nausea, vomiting, unintentional weight loss, and at 3 months later changes in bowel habits increased frequency and decreased consistency (Bristol-6), alternating with constipation (Bristol-1) ascites and pleural effusion.
