LETTER TO THE EDITOR: A patient with extended pneumonectomy for colorectal lung metastasis

Colorectal cancers take the second rank in deaths due to cancer. approximately 35% of patients have already had metastasis during diagnosis and 30% have one organ metastasis especially in liver or lungs. in this letter we aimed to report a 29 year old female patient with colon cancer metastasis in left lung who underwent pneumonectomy due to serious haemoptysis. she was diagnosed as colon cancer 4 years earlier and had undergone colon resection followed by chemotherapy. liver and lung metastasis were detected a little later for which she refused further chemotherapy.
