Most children with uveal melanoma have no systemic disease and only rarely have predisposing conditions such as dysplastic nevus syndrome or ocular melanocytosis.4 Our patient had neither of these conditions.

Clinicians should be cognizant that uveal melanoma can develop in a patient with MCD, especially in the setting of concurrent immunosuppression.
