Características Clínicas da Alopecia Frontal Fibrosante no Brasil: Série de 59 Pacientes

Introduction: Clinical characteristics of frontal fibrosing alopecia (FFA) have been studied since its description in 1994 in Europe, North America and Australia, and the present study is the largest on FFA features in Latin America. Methods: This study, through questionnaire and medical records, describes characteristics of a Brazilian population of 59 patients with FFA, concerning clinical forms, individual features and use of cosmetic products. Results: Mean patients’ age was 58.4 years (range 35-84y). Duration of disease varied from six months to 20y (median 5y). Most women were postmenopausal (83.1%) and non-smokers (83.1%). Five percent had at least one associated autoimmune disease, most commonly hypothyroidism (13.6%). Six of 40 patients (15%) had lichen planus pigmentosus and ten had facial papules (25%). Eyebrow alopecia occurred in 50 (84.7%), and body hair loss in 47 (79.7%). Facial papules were more prevalent in premenopausal women. Conclusion: Studying FFA epide- miology may help understanding the pathophysiology of this epidemic disease and this study highlights similarities and differences to previously published studies in FFA, such as greater frequency in postmenopausal women, association with hypothyroidism and facial irritation with cosmetic products.Introdução: A alopecia frontal fibrosante (AFF) foi inicialmente descrita em 1994 na Austrália, Europa e América do Norte, e este é o maior estudo sobre as características da AFF na América Latina. Métodos: Através de questionários e revisão dos processos clínicos, descrevemos as características de 59 pacientes com AFF, quanto à forma clínica, características indivi- duais e uso de produtos cosméticos. Resultados: A idade média dos pacientes foi de 58,4 anos (35-84 anos). A duração da doença variou de seis meses a 20 anos (mediana 5 anos). A maioria das mulheres encontrava-se na menopausa e (83,1%) e era não fumadora (83,1%). Cinco por cento tinham pelo menos uma doença autoimune associada, principalmente hipotireoidis- mo (13,6%). Seis pacientes (15%) apresentavam líquen plano pigmentoso e dez pápulas faciais (25%). Alopecia dos supracílios ocorreu em 50 (84,7%) e no corpo em 47 (79,7%). Pápulas faciais foram mais prevalentes em mulheres na pré-menopausa. Conclusão: Estudar a epidemiologia da AFF pode ajudar a entender a fisiopatologia dessa doença epidémica e este artigo traz algumas semelhanças e diferenças com estudos publicados anteriormente sobre a AFF, como maior frequência em mulheres na pós-menopausa, associação com hipotireoidismo e irritação facial com o uso de produtos cosméticos

Amiloidose nodular com lesão corimbiforme

Amyloidosis is part of a group of deposition diseases. Nodular amyloidosis is a rare form of primary cutaneous amyloidosis. It affects men and women, usually over the age of 60 years. Presenting manifestation of the disease are yellowish-erythematous or brownish nodules or plaques in single or multiple infiltrates. Systemic evaluation should be performed to rule out involvement of other organs. Follow-up of the patient is important because the condition may progress to systemic amyloidosis. We report a case of nodular amyloidosis in which the lesion had a corymbiform aspect without systemic involvement and no recurrence after two years of follow-up

Síndrome de Graham-Little-Piccardi-Lassueur: variante disseminada de líquen plano folicular

Graham-Little-Piccardi-Lassueur syndrome is a rare lichenoid dermatosis. It is characterized by the triad of scarring alopecia of the scalp, alopecia of the axilla and or groin, and keratotic follicular papules of the body. The present paper reports on two cases affecting young women. Histopathological findings suggest the disorder represents a generalized form of lichen planus follicularis
