Colorectal carcinoma developing during pregnancy is uncommon, estimated to affect <0.002% of pregnant women. Most patients present late in pregnancy, and more than 80% have rectal tumors (1). The presenting signs/symptoms, such as rectal bleeding, nausea, vomiting, and constipation, are often attributed both by the patient and physician to the pregnancy itself. We wish to call attention to the case of a 26-year-old woman (paral) who presented in the first trimester of gestation, at the emergency department with abdominal pain, vomiting, and fatigue, which was attributed to the pregnancy. These symptoms persisted throughout her pregnancy, but she gave birth to a healthy baby, delivered by cesarean section.
