Linear lichen planus pigmentosus and coincidental ipsilateral facial nerve palsy: An unusual observation

Lichen planus pigmentosus and association with autoimmune diseases: A case–control study

“…Our study is a pilot study and the first study from Tunisia seeking for LPP associated diseases. Our results were in agreement with previous studies from Japan, India and Kuwait regarding the clinico-epidemiologic aspects of LPP [3][4][5][6]. Nevertheless, we report a significant association between LPP and ADs (more than the quarter of our patients had associated ADs).…”

“…Lichen planus pigmentosus (LPP) is an uncommon variant of lichen planus (LP), characterized by the insidious onset of dark brown macules in sunexposed areas and flexural folds with or without slight pruritus [1,2]. It was originally reported from India, but it tends to occur also in other racial and ethnic groups such as Latin Americans, Middle Eastern population, Japanese and Koreans [3][4][5].…”

Dermosccopic features of progressive cribriform and zosteriform hyperpigmentation

“…This distinctive pigmentary dermatosis has five diagnostic criteria: (a) uniformly tan cribriform macular pigmentation in a zosteriform distribution, (b) histology showing an increase in basal layer melanin along with complete absence of nevus cells, (c) absence of history of rash, injury, or inflammation to suggest post-inflammatory hyperpigmentation, (d) onset well after birth with gradual extension, and (e) lack of other associated cutaneous or internal abnormalities [1,4].…”

Lichen striatus – case reports

“…It is a self-limiting eruption characterized by pink, tan or hypopigmented small papules distributed in a linear configuration. The diagnosis is based on clinical picture [1][2][3]. In this report we present 4 cases of Lichen striatus with typical lesions, described in 3 adults and one child, with good evolution and clue for etiology.…”
