Colitis or carcinoma?? a clinical dilemma a rare case of amoebic colitis masquerading as carcinoma caecum

Intestinal amoebiasis is caused by Entamoeba histolytica and is the second leading cause of death from parasitic infection worldwide1. It is mostly asymptomatic but rarely, it can develop into amoebic colitis and ameboma formation closely resembling colorectal carcinoma. Here we present a case of a 65year old male presenting to the emergency ward with complaints of pain in abdomen for past 6 days and inability to pass stools for past 2 days. Provisionally it was diagnosed to be a case of Subacute Intestinal Obstruction (SAIO) and patient was operated in the emergency for the same. The caecum was resected and sent to histopathology lab of Department of Pathology, JNMC, AMU. Gross examination and CT scan findings were suggestive of Subacute Intestinal Obstruction with carcinoma caecum but histopathological findings were consistent with Amoebic colitis.
