Intrathoracic neoplasms other than bronchogenic carcinoma.

Intrathoracic neoplasms other than bronchogenic carcinoma comprise a disparate group of tumors that have in common an anatomic location within the thorax. For the purposes of this review, they are divided into three categories: pulmonary metastases from locations other than the thorax, mediastinal neoplasms, and unusual primary lung neoplasms. This article reviews the recent literature; discusses evolving strategies for imaging, diagnosis, and treatment; and presents promising research developments.
