Histologic Findings

Pigmented lesions: Melanoma consists of varying proportions of spindle cells and epithelioid cells, with the latter cell types associated with higher malignant potential. Reports indicate a 17% incidence of glaucoma in ciliary body melanoma, 7% in iris melanoma, and 2% in choroidal melanoma. The predominant mechanism also varies with tumor location.
