Choroidal melanoma with synchronous Fuchs\u2019 adenoma and novel ATRX mutation

Abstract

BackgroundTo report a case of Fuchs’ adenoma occurring in an eye with a large choroidal melanoma. We have reviewed the literature to describe the clinical presentation, ultrasound characteristics and pathological features of these entities.Case presentationA 69-year-old Caucasian man presented with vision loss from a large choroidal melanoma. Enucleation showed an incidental Fuchs’ adenoma in the same eye. Whole-exome sequence analysis was also performed on the patient’s blood and melanoma, which showed a rarely-reported ATRX mutation.ConclusionsFuchs’ adenoma is an under-diagnosed benign age-related hyperplasia of the non-pigmented ciliary epithelium (NPCE). Given its location and characteristics, it can be mistaken for choroidal melanoma and clinicians are reminded how to differentiate between these pathologies and that they may co-exist.
