This article reports a case involving a synchronous silent metastatic rectal adenocarcinoma and metastatic large cell neuroendocrine tumor of the cecum and ascending colon. The patient presented with left sided abdominal pain and hematochezia with a noncontributory family, social, and medical history. This case presents a rare pathology not only due to the low incidence of synchronous gastrointestinal malignancies, but due to the unusual silent patient presentation.
