Introduction:
We report the clinical, imaging, histopathological, and genetic features of a choroidal metastasis originating from a cutaneous melanoma.
Case Presentation:
A 92-year-old woman presented with an asymptomatic pigmented lesion in her right eye. She had a history of prior cutaneous melanoma. Workup revealed widespread metastases to the liver, lungs, and brain. Histopathology (post-mortem eye) showed melanoma cells of the epithelioid cell type. Genetic analysis was positive for the BRAF V600K variant, confirming the cutaneous origin of the choroidal tumour.
Conclusion:
Choroidal metastasis of a cutaneous melanoma is a rare manifestation that can be mistaken for a primary choroidal melanoma. A comprehensive clinical history, histopathology, and genetic analysis are useful in distinguishing between the two entities.
