Wide skin markings pattern - melanoma descriptor or patient-related factor?

Abstract

We are intrigued by the findings reported in the letter titled "Uncovering the diagnostic dermoscopic features of flat melanomas located on the lower limbs"(1). Bassoli et al investigated the association of the "wider skin marking pattern" with cutaneous melanoma. They state that this feature corresponds to "…linear intercepting furrows, lighter than the lesion's overall pigmentation and wider compared to the surrounding skin. The authors conclude that "recognition of wider skin markings may…prompt the clinician to obtain a biopsy specimen." We respectfully ask the authors to clarify several aspects of their study methodology.
