Although the precise cause of the condition is unknown, as it is thought to be a variation of lichen planus, cell-mediated immunity—a type of immune system—may be a crucial factor in the development of the disease's clinical manifestation. [3]
Lichen planus What it looks like : Purplish lesions on the inner arms, legs, wrists, or ankles can signify lichen planus, a skin rash triggered by an overreaction of the immune system.
Lichen planus Pterygium unguis (or dorsal pterygium [ 1 ] : 660 ) forms as a result of scarring between the proximal nailfold and matrix, with the classic example being lichen planus , though it has been reported to occur as a result of sarcoidosis and Hansen's disease .

Examples include lichen planus, lichen sclerosus and lichen nitidus. It can also be associated with abrasion or drug use. [2] It has been observed in conjunction with the use of proton pump inhibitors, and might be a sign and/or symptom of lupus such as subacute cutaneous lupus erythematous, according to the case reports and reviews.
