RESUMEN
Acute iodide sialadenitis is a rare adverse reaction to iodinated contrast that causes self-limited salivary gland swell-ing. Its pathogenesis is still unclear, although kidney failure may be a risk factor. The diagnosis is initially clinical but angioedema, infections and lithiasis should be included in the differential diagnosis. No treatment or prophylaxis was proven to be beneficial. Although its prognosis is benign, associated complications have been reported. We report a case of 68-year-old man with swelling of the submandibular salivary glands after the administration of iodine-based contrast media during an abdominal computed tomography examination. Because of the widespread use of iodinated contrast enhanced imaging and interventional techniques, clinicians should be aware of this issue.

The organism whose cells come from different individuals is called chimera. It is frequently observed in nature: pregnancy, organ transplantation or transfusion are considered chimeric cell sources. It has been involved in autoimmune diseases development such as scleroderma, because of similarities between it and graft versus host disease, long term persistence of fetal cells in women and the finding of greater number of chimeric cells in affected women than healthy ones. It is not strictly a disease but might be considered helpful in non-invasive prenatal diagnosis and damaged organs regeneration.

We report the case of a male adolescent affected by Burkitt Lymphoma which presented as acute abdominal pain and rapid growth mass. It was characterized by computed tomography and diagnose was confirmed by bone marrow study. Two different chemotherapic regimens were used because of unfavourable evolution, but they were not successful. We consider some other causes of abdominal bulky in childhood, especially primary tumours and non tumoural diseases.
