Description
Pigmented fundus lesions associated with familial adenomatous polyposis (FAP) are multiple bilateral lesions, with poorly defined borders, sometimes depigmented, and a random, non-sectoral distribution. These lesions must be differentiated from solitary and grouped HCEPR in bear tracks. FAP is an autosomal dominant disorder that is associated with colon cancer in almost 100% of patients.
Comments
Pigmented lesions associated with FAP can be difficult to identify. Wide-field multimodal imaging techniques are very useful.
Indication
A 42-year-old male with FAP who, on wide-field fundus examination, presented multiple bilateral irregular pigmented lesions of different shapes and sizes, more easily appreciated when using the red filter and fundus autofluorescence.
