There are two basic kinds of medical test results: 1  Tests that give yes or no answers (usually used for diagnostic purposes) 2  Tests that give relative results, as in measuring something to be higher or lower, bigger or smaller than before, or inside or outside a normal range.
[edit on Wikidata] A melanocytic nevus (also known as nevocytic nevus) is a type of lesion that contains nevus cells (a type of melanocyte). Some sources equate the term mole with melanocytic nevus. Other sources reserve the term mole for other purposes.
A choroidal melanoma is a malignant tumor of the retina. It may spread (metastasize) to other parts of the body and can be fatal. It may be difficult for your eye doctor to differentiate a choroidal nevus from an ocular melanoma. As a retinal specialist, I am often asked to examine patients to make that differentiation.
