Multiple pulmonary fibroleiomyomatous hamartomata in childhood.

A 9-yr-old girl with a history of rhabdomyosarcoma developed multiple pulmonary fibroleiomyomatous hamartomata. This clinical setting illustrates the tendency of these hamartomata to clinically mimic metastatic tumors. Further, this case represents the first description of multiple pulmonary fibroleiomyomatous hamartomata in a pediatric age group, and finally, in this clinical setting, supports the concept that these hamartomata represent a distinct entity apart from benign metastasizing uterine leiomyomata.
