Ectopic nephrogenic rests in children: the clinicosurgical implications.

Introduction/background: Ectopic nephrogenic rests (ENR) are rare. The incidental discovery of these lesions in children has particular clinicosurgical implications, especially given the association between ENR and the development of extrarenal Wilms' tumors (ERWT).

Methodology: We reviewed the hospital records of patients with ERWT and ENR treated at our hospital over a 10-year period to identify those patients with histopathologically confirmed ENR and/or ERWT.

Thoracoscopy in Chest Wall Ewing's Sarcoma.

Minimally invasive surgery has a role in planning the resection of malignant chest wall tumors in the pediatric population. We studied the role of thoracoscopy in both the diagnosis and definitive surgery of chest wall Ewing's sarcoma tumors.
