Peripapillary choroidal melanomas. Extension along the optic nerve and its sheaths. 1978

H F Shammas, and F C Blodi

We reviewed 26 cases of peripapillary melanoma, 21 (80.8%) of which extended into the optic nerve or its meningeal sheaths. Most melanomas that extended into the optic nerve were necrotic and of the mixed or epithelioid cell type; all invaded the overlying retina and occurred in blind eyes with secondary glaucoma. The extension of melanoma cells into the subarachnoidal space was only influenced by the presence of the melanoma around the optic nerve head (peripapillary). The prognosis of these patients was highly dependent on the presence of orbital extension. A long piece of optic nerve should be excised when eyes with peripapillary melanomas are enucleated.

UI	MeSH Term	Description	Entries
D008545	Melanoma	A malignant neoplasm derived from cells that are capable of forming melanin, which may occur in the skin of any part of the body, in the eye, or, rarely, in the mucous membranes of the genitalia, anus, oral cavity, or other sites. It occurs mostly in adults and may originate de novo or from a pigmented nevus or malignant lentigo. Melanomas frequently metastasize widely, and the regional lymph nodes, liver, lungs, and brain are likely to be involved. The incidence of malignant skin melanomas is rising rapidly in all parts of the world.

D009900	Optic Nerve	The 2nd cranial nerve which conveys visual information from the RETINA to the brain. The nerve carries the axons of the RETINAL GANGLION CELLS which sort at the OPTIC CHIASM and continue via the OPTIC TRACTS to the brain. The largest projection is to the lateral geniculate nuclei; other targets include the SUPERIOR COLLICULI and the SUPRACHIASMATIC NUCLEI. Though known as the second cranial nerve, it is considered part of the CENTRAL NERVOUS SYSTEM.

D002830	Choroid Neoplasms	Tumors of the choroid; most common intraocular tumors are malignant melanomas of the choroid. These usually occur after puberty and increase in incidence with advancing age. Most malignant melanomas of the uveal tract develop from benign melanomas (nevi).
