{Abstract}: Malakoplakia is a rare granulomatous disease. Its aetiology is unclear but possible theories include infection with microorganisms (especially Escherichia coli), immunosuppression and impaired lysosomal function. It has been commonly documented to affect the genitourinary tract but can affect any organ, with the gastrointestinal system being the next most affected. We present a woman in her 70s, with a 2-week history of right-sided abdominal pain, 13 years following her renal transplant. She was admitted for treatment of an E. coli bacteraemia. CT scan had shown a caecal pole mass, highly suspicious for malignancy. It was surgically resected, and histology revealed findings of malakoplakia within the colon. Surgical intervention was combined with a prolonged course of antibiotics for successful treatment. We highlight the ability of malakoplakia to mimic malignancy and should be considered in the differentials in the context of an immunosuppressed patient with radiological findings of a colonic mass.
