The authors report on an infant who had multifocal mesenchymal hamarto
ma of the right posterior chest wall. The tumors were found incidental
ly, on a chest radiograph, during routine evaluation for upper respira
tory tract infection. Resection of both lesions with chest wall recons
truction was performed, with a good result. Only 46 cases of this unus
ual tumor have been reported previously, and only two of them were mul
tifocal. (C) 1996 by W.B. Saunders Company
