Late metastases: a rare cause of diarrhea.

Abstract

We present the case of a 64-year-old female with personal history of breast carcinoma diagnosed in 2011, treated and discharged from the Oncology service after 10 years disease-free who, 21 years after the diagnosis, undergoes a colonoscopy with biopsy sampling due to a 2-year period of diarrhea and weight loss, which histological study show infiltration of the large intestine's by breast carcinoma. Due to the usual lymphatic widespread, metastases of breast cancer in the gastrointestinal tract are extremely rare with nonspecific symptoms, long latency periods and poor prognosis.
