Lichen Striatus

Lichen Striatus: Clinical and Laboratory Features of 115 Children

“…The most frequently involved sites in our study were the limbs, with no substantial difference between upper and lower limb involvement (legs in 39, arms in 34), as previously reported (18,20). Our study therefore confirms that lichen striatus of the trunk is frequent, and in fact affected about one-third of our patients (5), and moreover, that facial involvement is not as rare as previously believed (1,2,5,18,20). In the present series, facial involvement accounts for 13% of cases, slightly more than in the Kennedy and Rogers series (11%) (10).…”

“…The occasional axial distribution of lichen striatus may thus be due to an illusory phenomenon when the trigger factor prefers this route. It is interesting to note that the recently described "drug line" (36) also supports this hypothesis, and this may help to explain the preferential location of lichen striatus on the limbs, particularly on the anteromedial surfaces of the arms and the posteromedial surface of the legs (43), a distribution that is quite evident in our series, as well as in those of other patients described in detail in the literature (1,2,5,13).…”

“…When reviewing the clinical photographs of some patients in the literature reported to be affected by lichen striatus, such a disposition appears quite evident [see case 1 of Muller et al (20)]. In 1941 Senear and Caro (1) reviewed 10 cases of lichen striatus and concluded that a single theory was not sufficient to explain the distribution of the lesions. They advanced doubts about the distribution of lichen striatus lesions always following Blaschko lines, since in some of their patients the pattern of distribution appeared to be along Voigt lines (PDLs); the photograms of cases 2 and 9 of these authors would, in fact, seem to confirm this opinion.…”

Lichen striatus: clinical and epidemiological review of 23 cases

“…LS is a relatively frequent dermatosis among children but there are only a few case series in the literature [1][2][3][4][5][6][7][8][9][10][11]. A comparison between our findings and those from the most relevant reviews of the literature is depicted in Table 1.…”

Nail Lichen Striatus and Its Differential Diagnoses

“…Nail involvement in LS has been first mentioned in 1941 [13]. Our review of the literature showed 37 LS cases (28 patients <18 years old; 9 patients ≥18 years old) with nail involvement.…”
