Though most cysts are diagnosed incidentally, some present directly with complications. We report on the case of an 11-month-old girl admitted for abdominal pain, fever and vomiting. Ultrasonography revealed intraabdominal fluid and the absence of a choledochal cyst diagnosed 2 months earlier. Laparotomy for suspected rupture of a choledochal cyst was planned and a choledochojejunostomy with Roux-en-Y was performed. Spontaneous rupture of a choledochal cyst is rare and occurs most frequently in children under the age of 4. The exact cause is yet unknown and several factors have been implicated. The most probable cause is the combination of pancreatic reflux and epithelial irritation of a weakened cyst wall. Choledochal cysts should preferably be treated as soon as the child is 6 months old. Complete excision of the cyst is mandatory because of the risk of malignant transformation.展开更多
Glomus tumors are rare distinctive benign neoplasms, which arise from modified smooth muscle cells of the normal glomus body and are most commonly located in the subungual region of the finger.

Intraabdominal locations are relatively rare. We report a case of glomus tumor of the mesocolon in a 10- yearold girl. Surgical exploration showed a lesion in the transverse mesocolon, which was excised. Histopathology showed it to be a glomus tumor of the mesocolon.展开更多

Their etiology is uncertain, and they are generally considered benign although some have a potential for rec urrence and dissemination. Recent studies have suggested, however, that some of these tumors are in fact neoplastic processes that harbor chromosomal aberration s similar to those seen in certain lymphomas. The authors report a case of infla mmatory pseudotumor of the ureter in a child and discuss recent reports.展开更多
