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 congenital nevus is a proliferation of benign melanocytes that is either present at birth or develops shortly afterwards. Congenital nevi are usually classified by size: small (less than 1.5 cm in diameter), medium (larger than 1.5 cm and up to 20 cm) or giant (measuring 20 cm in diameter or larger). This patient has a nevus spilus, a common benign melanocytic nevus with a speckled appearance. A nevus spilus can be macular or papular, exhibiting multiple smaller pigmented macules surrounding the central pigmentation. This lesion may be congenital or acquired and carries a small risk of malignant changes.
