[Clinical and pathologic characteristics of malignant lymphoma of the retina]

Two cases of malignant non-Hodgkin lymphoma of the retina and choroid with cerebral involvement are reported. In both cases, early infiltrates appear to have originated in the capillary layer of the choroid. Subsequently, Bruch's membrane was penetrated and tumorous infiltrates were found beneath the retinal pigment epithelium. The resulting reactions created a distinctive ophthalmoscopic picture, for which the term "leopardskin pattern" was coined. It may be helpful in early diagnosis, which with suitable therapy can prolong life.
