While the parallel ridge and parallel furrow patterns remain key diagnostic indicators of ALM and benign acral lesions, this systematic review and meta-analysis establishes the additional diagnostic significance of multicomponent and latticelike features. Nearly 20% of ALM lacked the parallel ridge pattern, demonstrating the need for new specific features for melanoma diagnosis. These findings provide evidence-based benchmarks to potentially improve diagnostic accuracy, guide dermoscopy training, and enhance early detection of ALM.
