Cytomegalovirus colitis in a child with leukemia: a case report.

A 17-month-old boy with a known case of T-cell acute lymphoblastic leukemia was admitted to the authors' hospital because of blood-streaked diarrhea a week after his last chemotherapy session. Initially, he was treated with supportive care and an empiric regimen for opportunistic causes of diarrhea; however, this was not effective. Eventually, evaluation of his stool with PCR showed positivity for cytomegalovirus. Consequently, he responded dramatically to treatment with ganciclovir. Although cytomegalovirus colitis is rare, a few case reports suggest cytomegalovirus as a possible cause of colitis in children with leukemia, which can be fatal and should be considered as a differential diagnosis.

Multifocal tuberculosis of long bones in an immunocompetent child.

Although tuberculosis (TB) is prevalent in many parts of the world, multifocal TB involvement of bones is rare. It is believed that less than 5% of skeletal TB is multifocal. We report a case of multifocal TB of long bones in an immunocompetent child. We describe the radiological and diagnostic features of TB osteomyelitis and outline its therapy and prognosis. To the best of the authors' knowledge, such a case with multiple long bone involvement without articular sequel and visceral involvement/constitutional symptoms has not been reported previously in the literature.
