Case Presentation                                                       Teaching Point
An otherwise healthy 37-year-old woman presented to                     Actinic lichen planus, also known as lichen planus subtropicus,
our clinic complaining of a rash on her lower eyelids that              is a rare photosensitive variant of lichen planus that typically af-
had been persistent for approximately one year. She de-                 fects young adults with dark complexion. ­Differing from classic
nied use of any cosmetic products on her face. On der-                  lichen planus, Koebner phenomenon, pruritus, mucosal or nail
matologic e­ xamination, the patient had well-circumscribed             involvement are commonly absent in actinic lichen planus [1].
erythematous, scaly, slightly hyperpigmented thin plaques                   Data on dermoscopic findings of actinic lichen planus
on lateral sides of both lower eyelids (Figure 1, A and B).             is scarce. A dermoscopic study on lichen planus variants re-
Lesions were asymptomatic and had increased in size                     ported presence of diffuse peppering on brown background in
during summer. Dermatoscopic examination revealed the                   all 10 lesions of 2 actinic lichen planus cases with the absence
presence of scales and perifollicular pigmentation on an                of Wickham striae and vascular patterns [2]. Similarly, diffuse
erythematous base (Figure 1C). Histopathology revealed                  peppering along with some hair follicles with central black dots
parakeratosis, basal vacuolar degeneration, necrotic kera-              was reported in dermoscopy of a case actinic lichen planus [1].
tinocytes, dermal lichenoid infiltration and melanophages                   We presented this case of actinic lichen planus, which is
(Figure 1, D and E). The patient was diagnosed with actinic             a less-known subtype of lichen planus with its different der-
lichen planus.                                                          moscopic findings.
