Lichen simplex chronicus (LSC) is thick leathery skin with exaggerated skin markings caused by sudden itching and excessive rubbing and scratching. [1] It generally results in small bumps, patches, scratch marks and scale. [1] It typically affects the neck, scalp, upper eyelids, ears, palms, soles, ankles, wrists, genital areas and bottom. [1]
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.

Tinea cruris is not life-threatening and treatment is effective, particularly if the symptoms have not been present for long. [5] However, recurrence may occur. The intense itch may lead to lichenification and secondary bacterial infection. Irritant and allergic contact dermatitis may be caused by applied medications.
Lichen sclerosus (LS) is a chronic, inflammatory skin disease, of unknown cause, which can affect any body part of any person, but has a strong preference for the genitals (penis, vulva), and is also known as balanitis xerotica obliterans when it affects the penis.
Morphea–lichen sclerosus et atrophicus overlap is characterized by both lesions of morphea and lichen sclerosus et atrophicus, most commonly seen in women. [ 3 ] : 171 Generalized morphea is characterized by widespread indurated plaques and pigmentary changes, sometimes associated with muscle atrophy, but without visceral involvement.
Lichen spinulosus is a rare skin disorder characterized by follicular keratotic papules that are grouped into large patches. [2] It is a variant of keratosis pilaris named for its resemblance to a patch of lichen .
Toxicodendron dermatitis lesions are often linear from brushing up against the plant. Causes of the Koebner phenomenon that are secondary to scratching rather than an infective or chemical cause include vitiligo, psoriasis, lichen planus, lichen nitidus, pityriasis rubra pilaris, and keratosis follicularis (Darier disease).
