Você conhece esta síndrome? / Do you know this syndrome?

A síndrome KLICK é uma genodermatose rara, autossômica recessiva, caracterizada pela associação de queratodermia palmo-plantar difusa e transgressiva, com esclerodactilia, placas hiperqueratóticas lineares localizadas preferencialmente em flexuras e ictiose congênita. Não há alterações em fâneros ou mucosas, assim como sintomas sistêmicos associados. O tratamento consiste no uso de queratolíticos tópicos e retinóides orais.

Keratosis linearis with ichthyosis congenita and sclerosing keratoderma (KLICK) syndrome is a rare autosomal recessive skin disorder characterized by the association of diffuse, transgressive palmoplantar keratoderma with sclerodactyly, linear hyperkeratotic plaques generally located in flexures, and congenital ichthyosis. The patient is physically and mentally healthy and has no history of any problems related to teeth, nails, hair or mucous membranes. Treatment is based on the use of topical keratolytics and oral retinoids.

Elastose perfurante serpiginosa em portadora da síndrome de Down / Elastosis perforans serpiginosa in a patient with Down's syndrome

A elastose perfurante serpiginosa é dermatose perfurante primária incomum, frequentemente associada a determinadas doenças genéticas e caracterizada por eliminação transepidérmica de fibras elásticas. Relata-se um caso raro dessa dermatose em paciente feminina de 19 anos, portadora da síndrome de Down, que apresentava pápulas eritematoceratóticas em arranjo arciforme, localizadas no antebraço e joelho direitos, assintomáticas, com cinco anos de evolução. Após confirmação histopatológica, foi iniciado tratamento com crioterapia, ocorrendo remissão parcial das lesões.

Elastosis perforans serpiginosa is a rare, primary perforating dermatosis, frequently associated with certain genetic diseases and characterized by the transepidermal extrusion of elastic fibers. The present case report describes this dermatosis in a 19-year old female patient with Down's syndrome, who presented with asymptomatic erythematous, keratotic papules in an arciform pattern, located on her right forearm and knee, which had been present for five years. Following histopathological confirmation, treatment with cryotherapy was initiated, resulting in partial remission of the lesions.

Síndrome do nevo de Becker: relato de caso / Becker's nevus syndrome: case report

O nevo de Becker se manifesta como uma mácula hipercrômica, localizada predominantemente no tronco anterior ou região escapular, e frequentemente associada à hipertricose. A coexistência do nevo de Becker e anormalidades cutâneas, músculo-esqueléticas ou maxilo-faciais corresponde à síndrome do nevo de Becker. Relata-se o caso de uma paciente de 16 anos, portadora desde os sete anos de mácula hipercrômica, localizada no tronco ântero-lateral direito, estendendo-se até a face medial da coxa direita, acompanhada de hipoplasia mamária ipsilateral. O exame anatomopatológico confirmou a hipótese clínica de nevo de Becker.

Becker's nevus is a hyperpigmented macula that is predominantly located on the anterior trunk or on the scapular region, frequently associated with hypertrichosis. The association of Becker's nevus with other cutaneous, musculoskeletal or maxillofacial anomalies has been called Becker's nevus syndrome. We report a case of a 16-year-old girl with a hyperpigmented macula which spread from her right anterolateral trunk to the inner part of her right thigh accompanied by ipsilateral mammary hypoplasia. The skin lesion started when the patient was seven years old when it was also noticed ipsilateral mammary hypoplasia. The histological exam confirmed the clinical hypothesis of Becker's nevus.

Clinical versus ultrasound examination in the evaluation of hepatosplenic schistosomiasis mansoni in endemic areas

The best way to appraise the size of abdominal organs remains undefined. Herein we compare the size of liver and spleen in hepatosplenic schistosomiasis using clinical and ultrasound (US) examination, and the size of the organs measured by US with their visualization below the costal margin ("palpable by US"). For this study, 411 individuals from an endemic area for schistosomiasis mansoni in Brazil have been selected. We found that palpable spleens and left liver lobes are larger than non palpable ones. Also, 23 percent of normal spleens measured by US were palpable on clinical examination, and 22 percent of spleens increased in size on US were non palpable. A total of 21 percent of normal spleens were "palpable by US". We also found 54 percent of normal sized right liver lobes palpable on clinical examination, whilst 54 percent of the increased livers, measured by US, were non palpable. About 76 percent of normal right liver lobes were "palpable by US". We conclude that the association of clinical, ultrasound and magnetic resonance imaging (MRI) examinations, in the near future, should give the investigators the necessary tools to perform a more accurate clinical diagnosis of hepatosplenic schistosomiasis mansoni.
