Abstract: INTRODUCTION: Lynch syndrome is a condition of predisposition to colorectal cancer and other tumors, associated with mutations in DNA mismatch repair genes, including MSH2. CASE REPORT:A 44-year-old woman presented with alterations in the distal digestive tract, a family history of colorectal cancer (mother) and ureter cancer, and a stenosing mass identified on colonoscopy. Genetic panel testing revealed a mutation in the MSH2 gene. RESULTS: Individuals with MSH2 mutations have an increased risk of developing endometrial, gastric, and upper urinary tract cancers compared with the general population and individuals of similar profiles. DISCUSSION: The presence of an MSH2 mutation increases susceptibility to several types of cancer and may generate psychological impacts on patients and families, particularly women at risk for gynecological malignancies. CONCLUSION: Genetic testing enables more individualized follow-up for patients and relatives, supporting quality of life and guiding therapeutic decisions.
