Pinpoint papular polymorphous light eruption in Asian skin: a variant in darker‐skinned individuals

Abstract

Our data suggest that pinpoint papular PMLE is not uncommon in darker-skinned individuals in our cohort.

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

“…[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. The common denominator appeared to be the filling and expansion of the papillae in the dermis with inflammatory infiltrate and edema.…”

“…[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. [12,13] Furthermore, the clinical morphology is so distinct in our patients that we may lose its value if an umbrella term of polymorphous light eruption (PMLE) is used for this subsets of patients.…”

“…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.…”

“…[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. [6][7][8][9][10] These reports have included small numbers of patients and biopsies, ranging from 1 to 25. We describe the clinicopathological features of the condition in 72 Indian patients seen in our hospital.…”

Photodermatoses in skin of colour

“…This variant was initially described in Indian and Japanese literature, characterized by 1–2 mm vesicles to erythematous papules on photoexposed body surfaces in skin phototypes IV–VI (Fig. b) . Areas of involvement predominantly include the upper extremities, head and neck and less commonly the face due to natural hardening .…”
