| Popis: | Background and Objectives: Immune check inhibitor (ICI) colitis is one of most common and adverse side effects of ICI. However, there was no case report of ulcerative colitis (UC)-mimicking colitis after atezolizumab use in hepatocellular carcinoma (HCC) to our knowledge. Materials and Methods: We would like to introduce the case of a patient with Stage IV HCC who complained of abdominal pain, diarrhea and rectal bleeding after two cycles of atezolizumab/bevacizumab chemotherapy and was then diagnosed with UC-mimicking colitis. Results: Endoscopy revealed typical findings of UC, suggesting diagnosis of UC-mimicking colitis. The patient was treated with systemic steroids and oral mesalamine, which significantly improved his symptoms, which were also supported by endoscopic findings. The patient resumed chemotherapy with atezolizumab and bevacizumab without any interruption to the chemotherapy schedule. Conclusions: Early endoscopic evaluation is pivotal to diagnosing UC-mimicking colitis. If diagnosed, UC-based treatments such as steroids and mesalamine should be strongly considered. Given previous reports of inflammatory bowel disease (IBD) flare-ups after immunotherapy, routine lower endoscopy, performed together with upper endoscopy before atezolizumab/bevacizumab therapy, is promising to patients. |
