The recipient lived in the United Kingdom,a non-endemic region for Histoplasmosis. However,she had previously lived in rural southern Africa prior to her OLT. The patient presented with iron deficiency anaemia,diarrhoea,abdominal pain and progressive weight loss. She reported no previous foreign travel,however,it later became known that following her OLT she had been on holiday to rural southern Africa. On investigation,a mild granulomatous colitis primarily affecting the right colon was identified,that initially improved with mesalazine. Her symptoms worsened after 18 mo with progressive ulceration of her distal small bowel and right colon. Mycobacterial,Yersinia,cytomegalovirus and human immunodeficiency virus infections were excluded and the patient was treated with prednisolone for a working diagnosis of Crohn's disease. Despite some early symptom improvement following steroids,there was subsequent deterioration with the patient developing gram-negative sepsis and multi-organ failure,leading to her death. Post-mortem examination revealed that her ileo-colonic inflammation was caused by Histoplasmosis.展开更多
