  • Title: Solitary tubercular caecal ulcer causing massive lower gastrointestinal bleed: a formidable diagnostic challenge.
    Author: Ram D, Karthikeyan VS, Sistla SC, Ali SM.
    Journal: BMJ Case Rep; 2014 Mar 06; 2014():. PubMed ID: 24604794.
    Abstract:
    Gastrointestinal (GI) haemorrhage is a common surgical emergency accounting for approximately 1% of acute hospital admissions. Lower GI bleed is less common and less severe than upper GI bleed and is usually caused by diverticulosis, neoplasms, angiodysplasia and inflammatory bowel disease. A 51-year-old man presented with massive lower GI bleed. He had no history of tuberculosis. He underwent colonoscopy and an isolated caecal ulcer was noted. Segmental ileocaecal resection was performed and no specific cause was identifiable on histopathology. PCR was performed on this specimen and it was positive for Mycobacterium tuberculosis. This case reports the unusual presentation of tuberculosis as solitary caecal ulcer with massive lower GI bleed and highlights the role of PCR as an adjuvant diagnostic tool for its diagnosis when characteristic histopathological findings are absent.
