Abstract
INTRODUCTION: While colorectal carcinoma is one of the most commonly diagnosed malignancies, its synchronous occurrence with other primary malignancies is rare.
PRESENTATION OF CASE: In this case, we describe the diagnosis and surgical intervention of a 55-year-old male patient who was found to have colonic adenocarcinoma at the hepatic flexure, right renal urothelial carcinoma, and malignant mesothelioma.
DISCUSSION: None of the previous studies reported these three distinct types of cancer, even in those patients with Lynch Syndrome. To the best of our knowledge, this is the first report of such case. The etiology and pathogenesis of multiple primary malignancies are complex. Common genetic and environmental risk factors that were found in different cancers might increase the risk of multiple primary malignancies.
CONCLUSION: The use of genetic testing and preoperative imaging studies should be considered to be invaluable tools for detecting synchronous malignancies. Practicing physicians should pay more attention to the risk of simultaneous separate primary malignancies.
