Lymphangiomyoma of the thoracic duct with previously undescribed epithelial tubules.
A case of mediastinal lymphangiomyoma with tubules covered with epithelium is reported. The epithelium of these tubules is morphologically identical to that of the bronchi. It is the first time that epithelial, presumably pulmonary, elements have been described in an extrapulmonary lymphangiomyoma. It is concluded that the present case of mediastinal lymphangiomyoma suggests a hamartomatous malformation. Whether this applies in general to lymphangiomyomatosis still remains a matter of discussion.
