Caecal amoebiasis mimicking colon neoplasm with secondary hepatic involvement

A 29-year-old female started to be investigated for multiple liver lesions suspected of metastases. The only one finding in colonoscopy was an ulcer in the caecum. Initial macroscopic diagnosis made at endoscopy was incorrect, taking into consideration possible colonic malignancy. Histology surprisingly revealed Entamoeba histolytica infection. Liver biopsy did not prove either amoebic abscess or metastasis but oral-con- traceptive-related focal nodular hyperplasia of liver. Treatment of amoebiasis with metronidazole was successful.
