Trichoscopy – a useful tool in the preliminary differential diagnosis of autoimmune bullous diseases

Abstract

Autoimmune bullous diseases present characteristic trichoscopic patterns. Trichoscopy can be regarded as a rapid in-office preliminary diagnostic method in the differential diagnosis of these diseases.

The Significance of Scalp Involvement in Pemphigus: A Literature Review

“…In 2017, our group described trichoscopic features of 26 patients with pemphigus vulgaris and 17 patients with pemphigus foliaceus [ 52 ]. We concluded that the presence of extravasations (20/26, 76.9%), yellow haemorrhagic crusts (19/26, 73.1%), dotted vessels with whitish halo (6/26, 23.1%), circular vessels (6/26, 23.1%), or polymorphic vessels (6/26, 23.1%) can suggest a diagnosis of pemphigus vulgaris [ 52 ].…”

The presence of dotted vessels, dotted vessels with whitish halo, clustered dotted vessels, dotted vessels forming “string of pearls,” and lace-like vessels correlated positively with PDAI scalp activity score [ 52 ].…”

Trichoscopy of scalp lesions in patient with erythroderma

“…Scalp is a common location of autoimmune bullous diseases [1]. We report a case of 52-year old woman presented with erythroderma associated with pruriginous erythema in the scalp.…”

“…Trichoscopy in a noninvasive tool for assessing scalp dermatosis [1]. They are only few reports on the interest of trichoscopy in pemphigus [1][2][3].…”

“…Trichoscopy in a noninvasive tool for assessing scalp dermatosis [1]. They are only few reports on the interest of trichoscopy in pemphigus [1][2][3]. Trichoscopy of scalp in foliaceus pemphigus found white diffuse scaling which can occurs also in psoriasis, allergic dermatitis and xerosis [1].…”
