Pediatric Melanoma in the Hispanic Population Presents at an Earlier Age and Is More Advanced

Pediatric melanoma in Hispanics presents at a younger age, has predominance in the lower limb, are Spitzoid melanomas, and are thicker tumors compared with non-Hispanic Whites (NHWs).

“We sought to document key clinicopathologic features of melanoma in Hispanic pediatric patients and to compare these parameters to pediatric NHWs under the a priori hypothesis that Spitzoid melanomas occur in greater proportions in Hispanics,” wrote the study authors.

Researchers performed a single-institution cross-sectional study of pediatric melanoma cases in Hispanics less than age 20 years.

Compared with NHWs, pediatric melanoma in Hispanic patients presented significantly younger (11.7 years; 95% CI, 2.77-8.00 years; P=.001), with lower limb predominance (46%; P<.05), mostly Spitzoid melanomas (82%; P<.05), and thicker tumors (2.34 mm; CI, 0.26-2.19 mm; P<.05).

“Pediatric melanomas may present differently in Hispanics, and heightened awareness/lower threshold to biopsy high‐risk Spitzoid tumors on the lower limb may be warranted,” concluded the study authors. –Lisa Kuhns
