ABSTRACT
Brazil is a country of continental dimensions with a large heterogeneity of climates and massive mixing of the population. Almost the entire national territory is located between the Equator and the Tropic of Capricorn, and the Earth axial tilt to the south certainly makes Brazil one of the countries of the world with greater extent of land in proximity to the sun. The Brazilian coastline, where most of its population lives, is more than 8,500 km long. Due to geographic characteristics and cultural trends, Brazilians are among the peoples with the highest annual exposure to the sun. Epidemiological data show a continuing increase in the incidence of non-melanoma and melanoma skin cancers. Photoprotection can be understood as a set of measures aimed at reducing sun exposure and at preventing the development of acute and chronic actinic damage. Due to the peculiarities of Brazilian territory and culture, it would not be advisable to replicate the concepts of photoprotection from other developed countries, places with completely different climates and populations. Thus the Brazilian Society of Dermatology has developed the Brazilian Consensus on Photoprotection, the first official document on photoprotection developed in Brazil for Brazilians, with recommendations on matters involving photoprotection.

Os neuromas encapsulados em paliçada são tumores neurais solitários da pele caracterizados pela presença de feixes compactos e paralelos de fascículos de células de Schwann. Apresenta-se um caso desse tumor, confirmado por exame anatomopatológico, em paciente do sexo feminino, de 55 anos, que relatou mácula hipocrômica de crescimento que evoluiu para pápula de superfície lisa e em domo, com telangiectasias, simulando carcinoma basocelular. Ter conhecimento dessa entidade é importante para a realização de diagnósticos diferenciais com outras lesões, em especial com o CBC, tumores de apêndice cutâneo, nevos e cistos epidérmicos.
Palisaded encapsulated neuromas are solitary neural skin tumors characterized by the presence of compact and parallel bundles of Schwann cell fascicles. The present article reports a case of this type of tumor, which was confirmed by anatomic pathological examination of a 55-year-old female patient who reported hypochromic macula growth, which had evolved into a smooth domed superficial papule with telangiectasias, simulating a basal cell carcinoma. Having knowledge of this entity is crucial in order to carry out differential diagnoses-comparing it to other lesions-especially basal cell carcinomas, skin appendage tumors, nevi, and epidermal cysts.
ABSTRACT
A aparência resultante da protusão da gordura orbital, agravada com discromia local, é esteticamente desagradável e piora com o envelhecimento. O objetivo deste trabalho érelatar o tratamento do sulco lacrimal de 15 pacientes com preenchimento de ácido hialurônico. O produto foi introduzido profundamente através de retroinjeção. Onze pacientes (73%) demonstraram satisfação após o procedimento. Dois casos (13%) apresentaram edema na região, um (6%) passou a salientar a hipercromia das pálpebras inferiores, e outro (6%) apresentou irregularidade na superfície cutânea preenchida, sendo tratado com hialuronidase. Essa técnica demonstrou bons resultados sem complicação grave.
The protrusion of the orbital fat, aggravated by local dyschromia, causes an unpleasant aesthetic appearance, which worsens with age. This study describes 15 cases of treating the tear trough with hyaluronic acid filling. The substance was deeply injected through retro injection. Eleven patients (73%) were satisfied with the procedure. Two cases (13%) presented edema in the treated area, one case (6%) developed hyperchromia of the lower eyelids, and another (6%) developed an irregularity on the cutaneous surface in the area that was filled, and was treated with hyaluronidase. This technique demonstrated good results, with no serious complications.
