Summertime Actinic Lichenoid Eruption, a Distinct Entity, Should Be Termed Actinic Lichen Nitidus

Lichenoid eruptions in children

“…These lesions have been described as summertime actinic lichenoid eruption, actinic LN, or LN actinicus. [65][66][67] Treatment…”

Photosensitive spongiotic/lichenoid eruption of micropapules and plaques: A morphologically distinct entity

“…Some workers found changes resembling lichen nitidus and this has led to their designating the condition actinic lichen nitidus or lichen nitidus actinicus. [3][4][5] In other studies, biopsies were reported to show spongiotic and lichenoid change. [1,[3][4][5][6][7][8][9][10] We found predominantly three patterns: spongiotic (43.7%), lichenoid (22.5%), psoriasiform (18.7%) and we also noted perivascular pattern in 4 (5%) specimens.…”

“…[1,[3][4][5][6][7][8][9] There is general agreement across studies on the distinctive clinical features of the disease: light to skin colored tiny papules, discrete and coalescing, on photo-exposed skin of the neck and upper limbs, usually sparing the face and occurring more commonly in women except in the Singaporean study where the eruption was common on the face and neck, and more common in men. [8] In contrast, the classic form of polymorphous light eruption, commonly affects the face and dorsa of the hands along with the other sun-exposed areas.…”

“…A total of 48 (66.7%) patients presented with their first episode while 24 (33.3%) had recurrent episodes (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12). Itching was mild in 31 (43.1%) patients, moderate in 30 (41.7%), severe in 10 (13.9%) and absent in a patient.…”

“…This entity has been described variously as summer time actinic lichenoid eruption (SALE), [1,2] actinic lichen nitidus, [3] and lichen nitidus actinicus. [4,5] A pinpoint papular variant of polymorphous light eruption in African Americans, in Singaporean patients of Asian origin and a micropapular light eruption in Japanese patients have also been described and appear to represent the same entity.…”
