Congenital Peribronchial Myofibroblastic Tumor: Case Report of an Asymptomatic Infant with a Rapidly Enlarging Pulmonary Mass and Review of the Literature

摘要

Background. Congenital peribronchial myofibroblastic tumor (CPMT) is a rare, benign lung tumor of infants, with only 19 reported cases worldwide. It is often diagnosed by prenatal imaging or in the immediate postnatal period due to co-morbidities like polyhydramnios, fetal hydrops, respiratory distress, and heart failure. Observation. We report the oldest known infant (8 weeks old) diagnosed with CPMT, and present his clinical course including the relevant radiographic and histopathologic findings. Conclusions. CPMT is a rare tumor that should be considered among other primary lung tumors of infancy (developmental, benign, and malignant) even if not detected prenatally or in the immediate postnatal period.
