TitleA left eye, showing a malignant melanoma
DescriptionA left eye, showing a malignant melanoma.
From an adult female.
The eye has been divided just lateral to its vertical equator and from the smaller half the vitreous has been removed, exposing a grey, lobulated neoplasm growing from the chorioid. The anterior chamber is shallow, the lens is cataractous, the pupil dilated and the iris atrophic. The tumour had caused a marked increase of intra-ocular pressure. Microscopic examination showed the structure of a malignant melanoma in which melanophores were more numerous than melanoblasts.
