Ethnic-type pigmentation is also often a polydactylic condition and family history helps in its diagnosisis the identification of the nature and cause of a certain phenomenon. Diagnosis is used in many different disciplines with variations in the use of logic, analytics, and experience to determine "cause and effect". In systems engineering and computer science, it is typically used to determine the causes of symptoms, mitigations, and solutions. As it predominates on the right hand in right-handed patients (and the opposite in left-handed) and occurs in darkskinned persons, it is likely that it could also correspond to some kind of repetitive trauma-induced pigmentation. Nevertheless, the dermoscopic aspect is similar, involving a grayish subtle dermoscopic pigmentation.
