Asians are a group with various skin phototypes, ranging from Fitzpatrick classification type III and IV in Chinese and Japanese populations and type IV and V in Indian and Pakistani populations. Asian skin tends to present post-inflammatory hyperpigmentation, melasma, lentigines and freckles, and nevi of Ota and Hori nevi. The main skin diseases reported include acne, atopic dermatitis and viral infections. Wrinkles and skin thickness are early signs of ageing in Caucasians but are less evident in Asian skin. Nevertheless, pigmentary changes occur earlier. The aim of this study is to show the importance of studying the characteristics of Asian skin in order to achieve better management of skin diseases in this population group that is increasingly common in the clinic. Based on a broad review of the literature, we report the characteristics of Asian skin, as well as some dyschromias and common skin disorders in this ethnic group.
Oleoma is a non-allergic, foreign body type granulomatous reaction. It appears as response to oily exogenous substances injected to the dermis or subcutis for aesthetical purposes. Treatment for localized lesions is surgical. When they are multiple, steroids may show some result.Newer therapeutic possibilities are being introduced and colchicine constitutes an alternative that is financially accessible and safe in moderate doses for certain dermatological illnesses. We present two women with oleoma on the legs treated with oral colchicine. This option was due to the extension of the clinical picture, which would not have a good surgical outcome. There was significant improvement in one patient, while we had to interrupt the medication in the other because of side effects.
A esclerodermia juvenil é uma doença que apresenta características diferentes em comparação com a esclerodermia no adulto. Sua incidência é rara na infância. Pode ser sistêmica ou localizada, sendo esta última a mais comum. Relatamos um caso de esclerodermia juvenil em uma criança de 3 anos de idade do sexo feminino apresentando placa amarelada no tronco simulando uma lesão xantomatosa. O halo lilás ao redor da lesão ajudou na formulação correta da hipótese diagnóstica confirmada pela histopatologia. O diagnóstico precoce no caso em questão, possibilitou a instituição do tratamento em uma fase inicial da doença, contribuindo para um melhor prognóstico do paciente.
