Percutaneous drain was inserted under tomodensitometric control and stayed in place until the follow-up at three weeks. Bacteriologic culture on the fluid sample demonstrated the presence of Escherichia coli and Streptococcus constellatus. The abscess completely regressed after 6 weeks of treatment and the biologic abnormalities resolved at the same time.Epstein-Barr virus [EBV] is a virus that infects almost all humans worldwide. After the acute phase of the infection, it stays in a latent form in B lymphocytes. EBV reactivation tends to occur in immunosuppressed patients. EBV reactivation may involve the gastrointestinal tract ; it has been associated mainly with colitis, but hemorrhagic enteritis has been poorly reported. Treatment usually includes antivirals. However, our patient did not respond to conventional treatment, so interferon alpha-2a was given as a salvage treatment. To our knowledge, this is the first reported case of hemorrhagic enteritis associated to EBV reactivation treated successfully with interferon alpha-2a.We report a case of colorectal involvement by a mantle cell lymphoma (MCL) that had been considered before as inflammatory bowel disease. Diagnosis of low-grade MCL can be difficult, and here we highlight the importance of thorough histopathological examination in case of supposed inflammatory bowel disease that does not react to therapy.Cobalamin or vitamin B12 (vitB12) is involved in DNA synthesis, haematopoiesis and myelinisation. Consequently, vitB12 deficiency causes various symptoms, such as megaloblastic anaemia, neurologic signs or pancytopenia. Despite possible severe symptoms, vitB
