Perifollicular erythema as a trichoscopy sign of progression in frontal fibrosing alopecia. Int J Trichology. 2013 ; 5(3):151-30974-7753http://hdl.handle.net/10668/1970Journal Article;INTRODUCTION Frontal fibrosing alopecia (FFA) in an entity characterized by the recession of the frontotemporal hairline (FTHL) with alopecic scarring change. In recent years there are numerous articles discussing the usefulness of dermoscopy for the clinical diagnosis of different types of scarring alopecia. MATERIALS AND METHODS We value 79 patients diagnosed with FFA, evaluating some trichoscopical findings described as typical for FFA: Absence of follicular opening, follicular hyperkeratosis, follicular plugs and erythema. RESULTS In a population of 79 women, 100% showed no follicular opening, 72.1% follicular hyperkeratosis, 66.3% perifollicular erythema and 44.8% follicular plugs. Thus, 100% of patients had at least one of the dermoscopic elements described as suggestive of FFA, 53% two of them, 45% three and 27%, all those elements. Perifollicular erythema was present in 95% of cases in which the disease was active. CONCLUSIONS We consider that the presence of perifollicular erythema will be a direct marker of FFA activity.enDermoscopydiagnosisfrontal fibrosing alopeciapatternExanthemaFemaleAlopeciaDermoscopíaEritemaEnfermedades del CabelloMedical Subject Headings::Diseases::Skin and Connective Tissue Diseases::Skin Diseases::Hair Diseases::Hypotrichosis::AlopeciaMedical Subject Headings::Anatomy::Tissues::Connective Tissue::Granulation Tissue::CicatrixMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Diagnosis::Diagnostic Techniques and Procedures::Diagnostic Imaging::Microscopy::DermoscopyMedical Subject Headings::Diseases::Skin and Connective Tissue Diseases::Skin Diseases::ErythemaMedical Subject Headings::Diseases::Skin and Connective Tissue Diseases::Skin Diseases::Hair DiseasesMedical Subject Headings::Organisms::Eukaryota::Animals::Chordata::Vertebrates::Mammals::Primates::Haplorhini::Catarrhini::Hominidae::Humansresearch article24574696open access10.4103/0974-7753.1256160974-9241PMC3927175
