Dento-osseous anomalies associated to familial adenomatous polyposis mimicking florid cemento-osseous dysplasia

Abstract

Familial adenomatous polyposis (FAP) is a colorectal cancer syndrome characterized by the development of multiple polyps of the colon and rectum with high risk of malignant transformation. The extraintestinal manifestations such as dento-osseous changes are associated with FAP. This is a case report of a 36-year-old female patient who was referred for dental treatment with the initial diagnosis of florid cemento-osseous dysplasia (FCOD). However, the association of the imaging dento-osseous findings with the medical history confirmed the diagnosis of FAP. The paper illustrates the clinical characteristics and imaging findings associated with FAP, and also discusses misdiagnosis based exclusively on imaging features.
