Core Tip

Core tip: Pseudomembranous colitis is mostly related to antibiotics, and it presents symptoms of diarrhea, abdominal pain, fever, hypoalbuminemia and hypovolemia. Diarrhea is the most common manifestation, but in geriatric patients, symptoms of pseudomembranous colitis can be different from those of usual cases, and the disease course can be more aggressive. For these reasons, it can be misdiagnosed. Therefore, physicians must consider pseudomembranous colitis in older patients with acute abdominal pain who have been treated with antibiotics. We report a case of an older patient with pseudomembranous colitis that was misdiagnosed as acute appendicitis.
