Introduction

According to the website of the American Cancer Society, an estimated 76,100 new cases of cutaneous melanoma will be recognized in 2014, and about 9700 annual deaths are expected from that tumor type. Yearly incidence rates for melanoma have risen steadily over the past 30 years, but the reasons for that observation are not fully understood. Malignant melanoma and histologically similar pigmented skin lesions are common diagnostic challenges, and pathologic interpretations thereof are often disputed among experts.
