Biopsy of the lesion revealed melanoma in situ; the lesion was excised with a 0.5cm border.
The lifetime risk of developing melanoma is 1 in 38 for non-Hispanic whites and 1 in 173 for Hispanics.1 However, the incidence of melanoma in Hispanics is increasing; from 1992 to 2008, cases of melanoma in this population in the United States rose by 19%.2 Hispanic individuals are 2.4 times more likely to present with advanced disease.1 Skin type in this population ranges from very light type I skin to very dark type VI skin.3 Factors that may contribute to delay in diagnosis include misconceptions about melanoma risk and lack of access to specialized care.1,4 Behaviors such as not wearing sunscreen, spending time in the sun, and tanning bed use increase the risk for melanoma.2
