Introduction: Although facial involvement in discoid lupus erythematosus (DLE) is common, eyelid involvement is atypical. Identifying this condition is challenging due to misdiagnosis, and it is essential to avoid potential deformities of the eyelid margin. Case Presentation: We, herein, report the dermoscopic findings in 2 female patients with a confirmed diagnosis of DLE who presented eyelids involvement. Discussion/Conclusion: This study highlights the importance of performing a dermoscopy examination to help physicians obtain an early diagnosis of DLE.
ABSTRACT
Trichotillomania is a compulsive disorder characterized by repetitive hairpulling. It is an important cause of patchy alopecia, especially in children between 9 and 13 years of age. The aim of this paper is to report 2 pediatric cases presenting with trichotillomania without patches. This condition may be extremely distressful, impacting psychosocial development of children. In these case reports, we reinforce the relevance of trichoscopy in hair disorder evaluation, which allowed early recognition to better advise and conduct these unique pediatric cases.
ABSTRACT
Frontal fibrosing alopecia (FFA) is a disease characterized by progressive band-like scarring alopecia involving the frontotemporal hairline and eyebrow hair loss. It affects mainly postmenopausal women. Trichoscopy features of FFA include absence of vellus hair, perifollicular erythema and scaling (peri-pilar casts), and absence of follicular openings. Trichoscopy of eyebrows in FFA patients shows tapered and broken hair, absence of follicular openings, black dots, and hair growing in different directions. We report a case of FFA with numerous pili torti in the eyebrows.
ABSTRACT
BACKGROUND: Frontal fibrosing alopecia (FFA) is a scarring alopecia that mainly affects postmenopausal women characterized by recession of the frontotemporal hairline and eyebrow loss. Current techniques to assess FFA activity are limited and involve noninvasive tools that assess disease progression or an invasive technique such as scalp biopsies. However, since progression of FFA is very slow, it is very important to develop a noninvasive technique to assess disease activity to monitor treatment response. OBJECTIVES: To provide a standardized and objective method to assess FFA activity. METHODS: We evaluated the correlation between trichoscopy and pathological features (degree of lymphocytic infiltration) in 20 dermoscopy-guided biopsies of FFA. At trichoscopy, we divided the severity of peripilar casts into 3 grades according to their thickness. To validate the trichoscopic visual scale, we showed the images to 7 dermatologists with interest in hair diseases. Concordance was assessed using the Kendall Tau-b concordance test. RESULTS: A strong correlation between severity of peripilar casts at trichoscopy and degree of lymphocytic infiltrate was observed by the Kendall Tau-b test. Validation showed very good inter- and intraobserver agreement. CONCLUSION: The trichoscopic visual scale allows noninvasive assessment of scalp inflammation in FFA in different scalp regions and therefore provides optimal guidance for treatment.
ABSTRACT
Nail involvement is a very common finding in patients with alopecia areata (AA). Most commonly evidenced by nail pitting, nail abnormalities can affect up to 66% of AA patients. We present two cases of the unusual association between habit tic nail deformities and AA.
ABSTRACT
Mesotherapy has recently become an advertised method for the treatment of different types of alopecia despite the lack of any data regarding its efficacy and possible side effects. The substances injected into the scalp include "cocktails" of natural plant extracts, homoeopathic agents, vitamins, vasodilators, and drugs that may stimulate hair growth, such as finasteride and minoxidil. We report two cases of patchy alopecia that developed after mesotherapy for the treatment of androgenetic alopecia. In the first patient, alopecia developed after injections of the heparinoid vasodilator mesoglycan; the 3-month follow-up examination revealed a small residual area of cicatricial alopecia. The second patient developed reversible alopecia after multiple scalp injections of homeopathic agents. These cases underline the possible risks of mesotherapy as a therapeutic technique for hair loss.
