Melanoma of uvea – http://id.who.int/icd/entity/136616595

A melanoma derived from melanocytes of the uveal tract. It is the most common primary intraocular tumour in the United States and Western Europe. Similar to melanoma of the skin, it is rare in Africa and Asia. Diagnostic procedures include ophthalmoscopic exam, fluorescein angiography and ultrasound. Classification of uveal melanomas recognizes four cell types within these tumours: epithelioid, intermediate, mixed cell, and spindle cell types. The spindle cell type uveal melanomas are further sub-classified as spindle cell type A and spindle cell type B.
