Primary pulmonary cancer colliding with metastatic choriocarcinoma

Zheng Wang, Jingwen Si, Jingwei Liu

Abstract

Collision tumors are rare in nature. Although lung is one of the main organs where metastatic tumors may occur, collision neoplasms consisting of a primary lung cancer and metastatic choriocarcinoma have never been reported so far. Here we describe a case of primary squamous-cell lung carcinoma (SCC) colliding with metastatic choriocarcinoma in a 55-year-old woman.
