Lichen planopilaris developed during childhood

Abstract

Lichen planopilaris is a disease that appears with lymphocytic cicatricial alopecia. It is considered a follicular variant of lichen planus. The examination of affected areas shows alopecia with perifollicular erythema and scaling, revealing a predilection for hair follicles. The involvement of children is uncommon, with few reports in this population in the literature. This study presents a clinical case of a male patient of 15 years of age with characteristic lesions of lichen planopilaris.

Diagnostic Accuracy of Trichoscopy in Inflammatory Scalp Diseases: A Systematic Review

“…Fifteen out of 22 studies reported loss of hair follicle units in a total of 296/356 (83.1%) patients [27, 29-42]. Milky red areas were described in 186/356 (52.2%) [31-33, 40], white fibrotic patches in 161/356 (45.2%) [31, 33, 36, 41, 42], and perifollicular erythema in 121/356 (34%) patients [29-31, 33, 35, 42]. Pigmented network, mostly scattered, was another frequent trichoscopic feature observed in 136/356 (38.2%) [29, 31-36] patients, followed by pigmented halo in targetoid pattern in 115/356 (32.3%) [17, 27, 28, 31-33, 43, 44], black dots in 114/356 (32%) [17, 27, 28, 31-33, 43, 44], white dots in 73/356 (20.5%) [4, 17, 27, 28, 32-44], and loss of vellus hair in 77/356 (21.6%) patients [31, 32, 37].…”

“…A total of 22 studies (15 original studies, 7 case reports) reported on trichoscopic features of lichen planopilaris. The analyzed group consisted of 356 patients [4,17,[27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46]. Vessels.…”

“…Scaling. Perifollicular hyperkeratosis was described in 227/356 (63.8%) patients [27,29,31,[34][35][36][37]. The presence of tubular casts was observed in 54/356 (15.2%) patients [17,28,[32][33][34][38][39][40].…”

“…Other. Fifteen out of 22 studies reported loss of hair follicle units in a total of 296/356 (83.1%) patients [27,[29][30][31][32][33][34][35][36][37][38][39][40][41][42]. Milky red areas were described in 186/356 (52.2%) [31][32][33]40], white fibrotic patches in 161/356 (45.2%) [31,33,36,41,42], and perifollicular erythema in 121/356 (34%) patients [29-31, 33, 35, 42].…”

Clinico-dermoscopic features and treatment responsiveness in pediatric alopecia – Experience from a tertiary care pediatric dermatology clinic

“…[ 15 ] Lichen planopilaris (LPP) is rarely reported in the pediatric population although it is not uncommon in adults. [ 16 17 ] In some of the large case series on pediatric LP from our and few other centers, LPP was conspicuous by its absence. In our study, it was observed predominantly in boys; perifollicular scaling and presence of scarring were commonly seen in lichen planopilaris which was similar to the one reported by Christensen et al .…”
