Infections in transplant recipients are associated with high morbidity and mortality, making their early recognition and treatment particularly important. Abdominal actinomycosis is a rare clinical entity and difficult to diagnose because of its various and nonspecific features. We describe a 57-year-old patient who presented with abdominal actinomycosis simulating colon cancer 6 similar to years after liver transplantation. The main symptom was abdominal pain. Abdominal computed tomography and colonoscopy revealed an intraluminal 4.5 similar to cm mass in the right colon, raising suspicions of a colonic malignancy and leading to surgical intervention. The postoperative pathologic study showed sulfur granules in the resected specimen compatible with abdominal actinomycosis. No signs of recurrence were seen throughout the 6-month follow-up. The literature on actinomycosis infections in immune-compromised hosts is reviewed. This presentation of actinomycosis in a liver transplant recipient has not been described previously, to our knowledge.
