1 Incidental Fuchs adenoma and iris pigment epithelial cyst, co-existing.

2. Collar-stud.

3. This case had a trans-vitreal FNA of the choroidal malenoma prior to enucleation.
Figure 3 is the pars plana. The discontinuation of the epithelium (both layers) and the fresh vitreous haemorrhage indicate that this is the site of the FNA. The FNA has induced the collar-stud melanoma growth pattern. There was no seeding of melanoma into the FNA site.
