Linear cutaneous lupus erythematosus

Linear Cutaneous Lupus Erythematosus with Calcinosis Cutis and Milia

“…In most cases the age of onset is younger than 15 years. Lesions appear as linear unilateral erythematous plaques and are observed most frequently on the face, although the neck, trunk, and extremities may also be affected . Neither photosensitivity nor disease progression to systemic lupus erythematosus is observed .…”

Linear cutaneous lupus erythematosus/discoid lupus erythematosus in an adult

“…It occurs mainly in children and young adults. Lesions appear as linear unilateral erythematous plaques following the Blaschko lines and are observed most frequently on the face, although the neck, trunk and extremities may also be affected [2]. Neither photosensitivity nor progression to systemic LE is observed [3].…”

“…The LCLE occurs mainly in children and young adults, with a similar incidence in both sexes, without ethnic preference. Lesions appear as linear unilateral erythematous plaques and are observed most frequently on the face, although the neck, trunk and extremities may also be affected [2]. Most commonly, anti-nuclear antibodies are negative or slightly positive.…”

“…These findings are compatible with DLE [3]. Differential diagnosis must be established with other conditions with Blaschko linear distribution such as linear lichen planus, lichen striatus, linear granuloma annulare, linear psoriasis, morphea or inflammatory linear verrucous epidermal nevus [2]. The treatment of linear cutaneous LE includes potent topical corticosteroids or calcineurin inhibitors.…”

“…To our knowledge, there have been only nine previous confirmed cases of LCLE/DLE in adults, which all followed Blaschko lines [2, 5–11] (Table 1). The incidence in both sexes seemed similar.…”
