Reason dictates that rapidly growing melanomas carry a worse prognosis than those that are quiescent. Indeed, much focus has been given to calculating the growth index of melanomas as defined by their mitotic rate1,2—a process that requires counting the number of mitoses in several high-power fields. As expected, mitotic rate has been found to correlate with and predict morbidity and mortality for melanoma2 and therefore has become a routine part of the histologic examination of these tumors.3
