Abstract
The mediastinum is a unique anatomic area containing various structures and pluripotent
cells, which allow for the development of a range of tumors. We report two pediatric
cases of a lipomatous tumor of the posterior mediastinum. Complete surgical excision
of the mass in each was achieved through a lateral thoracotomy. Histopathologic findings
showed a lipoma in one case and a lipoblastoma in the other. A lipomatous tumor in
the posterior mediastinum is extremely rare and preoperative diagnosis is difficult.
When an operative plan is being considered, the presence of a potentially malignant
tumor should be kept in mind.
