A number of variants of blue nevi with corresponding histologic changes have been described , including epithelioid blue nevus ( classic description is with the Carney complex , but also is seen without this condition ) , atypical blue nevus , deep penetrating blue nevus , sclerosing blue nevus , and amelanotic blue nevus . The width of the halo is variable but is generally of uniform radial distance from the central nevus ( see Image 1 ) . These include LSN , linear nevus comedonicus ( NC ) , linear epidermal nevus ( LEN ) , and inflammatory linear verrucous epidermal nevus ( ILVEN ) . But the marathoners had more dysplastic nevi ( atypical moles , which can become malignant melanoma ) and more liver spots . A doctor will also look for other physical signs , such as eyes that almost always look down and a lot of white showing above the irises ( " sun-setting of the eyes " ) . The main objective of this in vitro study was to demonstrate the applicability of infrared spectral imaging to separate , on paraffinised biopsies , pigmented nevi ( benign skin lesions ) from melanomas ( malignant skin lesions ) . These filters serve multiplexing purposes ( before or after amplification ) , and consist of a sequence of cylindrical hollow bodies , magnetically coupled by irises ( orthogonal double slits ) . The plural of nevus is nevi ( NEE-vye ) . ICE syndrome is actually a grouping of three closely linked conditions : iris nevus ( or Cogan-Reese ) syndrome ; Chandler 's syndrome ; and essential ( progressive ) iris atrophy ( hence the acronym ICE ) .

Director of the Pigmented Lesion Clinic where patients with numerous nevi ( moles ) , atypical nevi , and family or personal history of cutaneous melanoma are seen . The mean Hamming Distance between genetically identical irises is 0.497 with standard deviation 0.031 , which is statistically indistinguishable from comparisons between 9.1 million pairings of genetically unrelated irises ( histogram provided here ) . Nevus depigmentosus and ILVEN may occur together , as may ILVEN and melanodontia.Linear sebaceous nevus ( Jadassohn nevus phacomatosis ) In 84 % of patients with LSN , skin lesions are on the face , and in approximately 50 % , lesions are on the scalp , the neck , and the forehead .
