Otherwise, weight loss, fatigue and weakness do not suggest colorectal carcinoma. Carbohydrate antigen (CA) 19-9 level is higher in several malignancies, especially gastrointestinal malignancies, and some benign conditions. Herein, we present a patient who is referred to our clinic with the complaint of fatigue and significant CA 19-9 elevation, diagnosed as metastatic colorectal carcinoma. Presenting case highlights that CA 19-9 elevation might be the only finding of colorectal carcinoma in even patients with nonspecific complaintseninfo:eu-repo/semantics/openAccessArticle53914918227661
