Translation into Portuguese language (Brazil), transcultural adaptation and validation of the quality of life questionnaire in female pattern hair loss (WAA-QoL-BP)

Abstract: Background: Female pattern hair loss (FPHL) is a common complaint in adult women and inflicts major impact in quality of life, however, there is no specific questionnaire available in Portuguese for such evaluation. Objectives: Translation into Brazilian Portuguese, cultural adaptation and validation of the WAA-QoL (Women's Androgenetic Alopecia Quality of Life Questionnaire). Methods: Methodological study. After authorization by the author, cultural (linguistic) translation and adaptation to Portuguese of the WAA-QoL questionnaire were carried out. The translated version (WAA-QoL-BP) and DLQI (Dermatology Life Quality index) were submitted to patients with FPHL for concurrent validation. Twenty patients were reevaluated to assess temporal stability. Results: A total of 116 patients with APF were evaluated, the mean age (SD) was 47 (14) years, and 89 (76%) patients were classified as grades II and III (Sinclair). There was high internal consistency: Cronbach´s alpha was 0.97 for the WAA-QoL-BP and 0.87 for the DLQI. The correlation between WAA-QoL and DLQI resulted in (rho) 0.81 (p <0.01). The intraclass correlation coefficient for complete agreement of WAA-QoL-BP was 0.95 (p <0.01) in the test-retest comparison. Study Limitations: Sampling of patients only from the State of São Paulo. Conclusions: A Brazilian version for WAA-QoL was translated and adapted, which proved to be valid and consistent.

Case for diagnosis. Linear Darier's disease

Abstract: We present a different and rare manifestation of Darier's disease, namely linear Darier's disease. Only a few cases have been described in the literature. The case report is a male patient, 60 years old, presenting brown to red papules and plaques with hyperkeratosis distributed on the abdomen, following Blaschko's lines, with 6 years' evolution.

Ictiose lamelar com apresentação na vida adulta: relato de caso / Ichthyosis lamellar with presentation in adult life: case report

Contexto: A ictiose lamelar é uma genodermatose rara, de herança autossômica recessiva. Pode ser causada por diferentes genes, principalmente mutação no gene TGM1 (transglutaminase 1) no cromossomo 14, e tem incidência de 1 caso em cada 200 mil nascidos vivos. A ictiose lamelar é causa de importante impacto na qualidade de vida. Relato da comunicação: Paciente do sexo feminino, 44 anos, procura atendimento médico para investigação de sintomas psiquiátricos, os quais foram avaliados. Foi afastado qualquer quadro psiquiátrico. Encaminhada à dermatologia, devido a evidente descamação lamelar disseminada, queratodermia palmoplantar, onicodistrofias e ectrópio bipalpebral. O exame clínico dermatológico e a avaliação histopatológica, evidenciaram características de ictiose lamelar, nunca tratada. Discussão: A ictiose lamelar é, na maioria das vezes, diagnosticada ao nascimento, com apresentação clínica muitas vezes sob a forma de bebê colódio. Este caso apresentou-se na vida adulta, com história desde o nascimento e, portanto, descartou-se a ictiose adquirida, relacionada a afecções nutricionais, metabólicas ou até paraneoplásicas. Conclusões: Este caso ilustra as manifestações da ictiose lamelar em paciente adulta em sua evolução natural, sem a interferência de tratamento.

Patch-type granuloma annulare: a case report

Granuloma annulare (GA) is a benign, self-limited condition which the etiology remains unknown. It is clinically characterized as annularly, erythematous papules on the extremities. Histologically, it shows as palisading granulomas with central degenerated collagen and mucin deposits. The patient in this case report had a rare GA variant named patch-type GA. It appeared as asymptomatic erythematous macules with central clarification on the upper portion of thighs. Histopathology was compatible with interstitialtype GA. We highlight that a high index of suspicion is necessary to make the diagnosis of patch-type GA and confirmation can only be achieved through histopathology study. (AU)

O granuloma anular (GA) é uma condição benigna, autolimitada e de etiologia desconhecida. Clinicamente é caracterizado por pápulas eritematosas anulares nas extremidades. Do ponto de vista histológico, observa-se a formação de granulomas com colágeno degenerado em sua porção central e depósito de mucina. O paciente deste caso clínico foi diagnosticado com uma variante rara de granuloma anular, na sua forma macular. A lesão se apresentava como máculas eritematosas assintomáticas na porção superior das coxas. Nos cortes histológicos, o quadro era compatível com GA do tipo intersticial. Neste trabalho enfatiza-se a necessidade de um elevado índice de suspeição clínica para o diagnóstico de GA macular e a confirmação só poderá ser alcançada através do estudo histopatológico. (AU)

Kissing nevus of the penis: a case report and dermatoscopic findings

Abstract Divided nevus, also known as kissing nevus, is a rare variant of congenital melanocytic nevi in which there are two adjacent nevi in areas of the body that undergo embryonic cleavage. The original description of this type of lesion was on the eyelid. The location on the penis is even rarer, with only 17 case reports in the literature so far, and only one of them described the dermoscopic findings. We report the case of a patient with divided nevus of the penis and its clinical, dermoscopic and histopathological features.
