Development of Port-Site Metastases Following Thoracoscopic Resection of a Neuroblastoma.

We report a 26-month-old female who developed port-site metastases of a neuroblastoma following minimally invasive thoracoscopic interventions. After diagnosis of an intrathoracic low-risk neuroblastoma and 6 months of observation, she developed respiratory problems. She subsequently underwent total resection of a locally progressive tumor via thoracoscopy. Six months later, she developed local relapse and subcutaneous metastases within the thoracic wall. These port-site metastases were most likely iatrogenic. After excision of metastases, the residual tumor responded well to salvage chemotherapy. The patient has remained in remission for over 4 years.
