ABSTRACT
A 69-year-old woman was admitted to our hospital because of cough and dyspnea. Chest CT scan revealed lymphangiosis carcinomatosa, but no masses considered as primary lung cancer was seen. Both results of transbronchial lung biopsy (TBLB) and colon biopsy showed adenocarcinoma, and immunohistochemistry results diagnosed primary colon cancer with lung lymphangiosis carcinomatosa. Lymphangiosis carcinomatosa is mostly associated with primary lung, breast, and gastric cancer, but pulmonary lymphangiosis carcinomatosa caused by colon cancer is rare. When pulmonary lymphangiosis carcinomatosa is detected, we should consider the possibility of colon cancer, and TBLB should be performed.
