Intrathoracic lipoblastoma in a 15-month-old infant

Abstract

Lipoblastoma is a rare tumor of infancy. It originates from the white fetal fat in soft tissue. The most common location of this rare tumor is extremity and to best of our knowledge less than 10 cases of intrathoracic and mediastinal lipoblastoma has been reported in the English literature. Herein we present our experience with a 15-month-old boy infant who presented with severe dyspnea. Imaging studies showed a mass in the thoracic cavity and mediastinum which was diagnosed as lipoblastoma after pathologic examination of the resected mass. Lipoblastoma has been considered as a tumor of soft tissue, but it should also be considered as a rare cause of intrathoracic masses of young children.
