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.
Large and giant congenital melanocytic nevi often have both biological and cosmetic implications. Large congenital nevi have a low but real risk for secondary malignant transformation and the development of melanoma. Some data suggest that melanoma can develop within a giant congenital melanocytic nevus in up to 5% of cases.
