Review of autopsies of 28 children with severe combined immunodeficiency (SCID) or combined immunodeficiency (CID) and three with DiGeorge syndrome showed a high incidence of acute graft-versus-host disease (GVHD) in the pancreas. Acute GVHD (seven cases: four SCID, two CID, and one DiGeorge syndrome) was characterized by lymphocytes around large to medium ducts, damage to ductal epithelium (focal necrosis, reactive nuclear changes, inspissated secretions in duct lumens), and periductal edema. Changes were judged indeterminate but suspicious for GVHD when ductal damage was slight (six cases: three SCID, two CID, and one DiGeorge syndrome). All patients with pancreatic GVHD had received allogeneic bone marrow, fetal liver or thymus transplant, or nonirradiated blood products and had evidence of GVHD in other organs. Immunoperoxidase stain for HLA-DR showed strong-to-moderate staining of duct epithelium in two of four GVHD cases for which blocks were available. This change was nonspecific; weaker staining for HLA-DR was seen in cases with nonspecific abnormalities and in viral pancreatitis. Four cases had histological evidence of viral infection: two had cytomegalovirus pancreatitis, one had patchy parenchymal necrosis caused by adenovirus, and one had giant cell pancreatitis caused by parainfluenza virus. Mild nonspecific changes, such as focal fat necrosis or acinar dilatation, were seen in seven cases. One case had unexplained marked pancreatic atrophy and fibrosis. Acute pancreatic GVHD is not uncommon in autopsies of children with congenital immune deficiencies with GVHD of other organs; however, this finding may not have strong clinical implications in this group of patients. Careful attention to pancreatic ducts is necessary for diagnosis. Unusual viral pancreatitis may also be seen in this group, as well as nonspecific abnormalities.

Duplication 22q11.2 syndrome is the result of a microduplication of the same chromosomal region that is deleted in DiGeorge and Velocardiofacial syndromes. We describe a patient with dysmorphic features who was diagnosed with pre-B acute lymphoblastic leukemia, and developed cystinuria and pancreatitis during treatment. Duplication 22q11.2 has not been previously described in association with hematologic abnormalities. Chromosomal microarray technology was used to diagnose duplication 22q11.2 syndrome. In this era of advanced genomics, this technology has become an important method for helping to determine the molecular basis of diseases, best treatments and ultimately patient outcomes.

In pediatric age, duodenal hematoma is rare and generally occurs following a closed abdominal trauma due to the crushing of the duodenum against the rigid plane of the spine; it rarely follows anticoagulant therapy, pancreatitis, bleeding disorders, vasculitis, tumors or upper digestive endoscopy. Duodenal hematoma is a rare cause of obstruction of the upper gastrointestinal tract and acute pancreatitis, and the diagnosis is sometimes difficult and late. On the other hand, the identification of the pathology in its initial stages allows the young patients to be subjected to a conservative treatment that resolves the issue most of the time, thus avoiding surgery. In this article we describe an unusual case of duodenal hematoma, following esophagus-gastro-duodenoscopy, in a 12-year-old boy with Di George syndrome.
