| Popis: | Purpose of review To illustrate retinal pigment epithelium hamartomas (RPEHs) in a patient with known Turcot syndrome and to demonstrate the significance of these lesions in other colonic polyposis syndromes. Recent findings The presence of multiple, bilateral RPEHs is a specific marker for familial adenomatous polyposis (FAP). Recent studies have noted RPEHs in associated syndromes including Gardner and Turcot syndromes. Herein, we illustrate an 18-year-old male patient with known brain medulloblastoma who was documented 7 years later to have asymptomatic RPEHs in both eyes, demonstrating hypo-autofluorescence. Summary This patient with previous medulloblastoma and known Turcot syndrome was later found to have typical RPEHs, a feature that is important in family screening. Confirmation of RPEHs related to Turcot syndrome was made, and genetic evaluation confirmed germline mutation in the adenomatous polyposis coli (APC) gene. Observation was advised. Due to the fairly rapid progression to colorectal cancer if untreated, ophthalmologists should be aware that RPEHs can be the first extracolonic manifestation of FAP, Gardner syndrome, and Turcot syndrome. |
