Rebound Thymic Hyperplasia after Chemotherapy in Children with Lymphoma.

Background: Development of mediastinal masses after completion of chemotherapy in pediatric patients with malignant lymphoma is worrisome and challenging to clinicians.

Methods: We performed a retrospective review of 67 patients with lymphoma treated at our hospital from January 1, 2001 to June 1, 2013. Patients who received at least two chest computed tomography (CT) examinations after complete remission (CR) was achieved were further analyzed.

Dislodgement of port-A catheters in pediatric oncology patients: 11 years of experience.

Background: Port-A catheters are frequently used in pediatric cancer patients. Their dislodgement is potentially seriously risky although the incidence is not high. We analyzed our 11 years of data to address this important problem.

Pediatric malignant ovarian tumors: 15 years of experience at a single institution.

Background: Malignant ovarian tumors in children are relatively rare. We reviewed our 15-year experience to understand their clinical presentations, managements, and prognoses.

Methods: There were 15 children who were diagnosed to have malignant ovarian tumors from January 1994 to June 2009 in our hospital.
