A rare case of lung cancer associated with renal cell cancer and benign histiocytoma of bone

Abstract

Lung cancer often metastasizes to organs outside the thorax, and consequently radiological evaluation of distant metastasis has become standard procedure prior to surgery. Although positive radiological findings generally suggest distant metastasis, the possibility of the co-existence of a benign tumor and primary malignancies must be considered. Herein we report a case of surgical resection of histologically confirmed lung cancer associated with renal cell cancer and benign histiocytoma of the humerus.
