title: Resectable pulmonary nephroblastoma metastases presenting as chest wall lesions on radiography. A report of 2 cases.
abstract: Two children with pulmonary metastases from nephroblastomas showed the radiological features of chest wall tumour involvement. Diagnostic surgical exploration subsequently revealed pedunculated and fully resectable peripheral lung metastases. The mechanism by which these pedunculated lesions mimicked the classic 'D sign' of an extrapulmonary (pleural or chest wall) tumour is explained.
