Owing to the pigmentation, MAs may mimic the clinical appearance of malignant melanomas (MMs). However, the dermoscopic patterns of MAs and MA-like MMs have rarely been compared.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objective<\/jats:title>\n                    <jats:p>To elucidate the clinical and dermoscopic differences between MAs and MA-like MMs.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This study included 77 MA and 33 MA-like MM patients.

Crypts, comedo-like opening, milia-like cysts, fissures, and hairpin vessels appeared more frequently in MAs ( P &lt; .05). However, atypical pigment networks, blue-white veils, pseudopods and streaks, and atypical vessels were more common in MMs ( P &lt; .05). MAs often showed melanoma-specific dermoscopic findings, especially blue-white veils (22.1%). Furthermore, fissures (42.4%), crypts (21.2%), and comedo-like openings (15.2%) were observed in MMs, although they are typically benign patterns.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Differences in dermoscopic patterns might provide important clues for the differential diagnosis of MA-like lesions. However, MAs such as MMs and true-benign MAs may overlap clinically in appearance and on dermoscopy. Several benign patterns were frequently observed in MMs (fissures, globular pattern, crypts, comedo-like openings, cerebriform appearance, and milia-like cysts), and several malignant patterns were observed in MAs (blue-white veil, pseudopod, and atypical pigment network). Importantly, if any of the melanoma-associated features or atypical vessels are present, the lesion should be biopsied to establish a diagnosis.<\/jats:p>\n
