Small Malignant Melanoma of the Choroid With Extraocular Extension

Archives of Ophthalmology, 1981
A disciform macular lesion in the hyperpigmented eye of a patient with melanosis oculi demonstrated slowly progressive increase in size during eight years. Clinical observation and serial fundus photography indicated increase in anteroposterior thickness of the lesion to 2.0 mm and in greatest diameter from 3.5 to 6.0 mm. Subsequent echography revealed

Clinically Stationary Choroidal Melanoma With Extraocular Extension

Archives of Ophthalmology, 1978
A malignant melanoma of the choroid was observed for three years because of an erroneous diagnosis of disciform macular degeneration. No lateral or vertical growth was noted during the observation period, but significant extrascieral extension was discovered at the time of radioactive phosphorus uptake test and enucleation.

Melanosis Oculi, Small Choroidal Melanoma, and Extraocular Extension

2015
In a white patient with melanosis oculi, a small choroidal melanoma in the hyperpigmented eye was observed for 8 years before enucleation. An important factor in the decision to enucleate was echographic evidence of extraocular tumor extension. Histopathologic examination confirmed the presence of a small choroidal melanoma (with an intraocular tumor ...

Extraocular extension of malignant melanoma of the uvea.

Canadian journal of ophthalmology. Journal canadien d'ophtalmologie, 1983
Two patients, each with a large malignant melanoma of the choroid, underwent enucleation of the affected eye. Gross examination of each globe in the pathology laboratory disclosed a substantial area of extrascleral extension of the intraocular neoplasm, although this had not been noted at the time of enucleation.
