A Rare Synchronous Tumor Association in a Geriatric Patient: Lung Adenocarcinoma and Colon Carcinoma

The incidence of synchronous colorectal and lung cancer is very low and rare. We present the case of a geriatric patient with tumors in the transverse colon and right pulmonary hilum. This case report aims to draw attention to the rare synchronous colon and lung cancer. Treatment of synchronous tumors is different from the treatment of other primary cancers. If possible, radical resection of both tumors should be performed when synchrony is detected. Since our patient was metastatic, a chemotherapy protocol that is effective on both tumors was started. Chemotherapy regimens are also quite different in these patients. Therefore, effectively differentiating synchronous cancers from colorectal cancer with pulmonary metastases has important therapeutic implications for these patients.
