Polyps in the colon along with extracolonic tumors are characteristics of?

1. Gardner's syndrome

2. Lynch syndrome

3. Peutz-Jeghers syndrome

4. Familial adenomatous polyposis

The correct answer is: Gardner's syndrome

Polyps in the colon along with extracolonic tumors are characteristic features of Gardner's syndrome. Gardner's syndrome is a subtype of familial adenomatous polyposis (FAP), an autosomal dominant inherited disorder. Individuals with Gardner's syndrome typically develop numerous colorectal polyps, along with extracolonic manifestations such as osteomas (benign bone tumors), epidermoid cysts, desmoid tumors, and other soft tissue tumors. This distinguishes Gardner's syndrome from the other syndromes listed: Lynch syndrome, Peutz-Jeghers syndrome, and familial adenomatous polyposis (FAP) without extracolonic tumors.
