ABSTRACT
Abstract: Skin disease occur worldwide, affecting people of all nationalities and all skin types. These diseases may have a genetic component and may manifest differently in specific population groups; however, there has been little study on this aspect. If population-based differences exist, it is reasonable to assume that understanding these differences may optimize treatment. While there is a relative paucity of information about similarities and differences in skin diseases around the world, the knowledge-base is expanding. One challenge in understanding population-based variations is posed by terminology used in the literature: including ethnic skin, Hispanic skin, Asian skin, and skin of color. As will be discussed in this article, we recommend that the first three descriptors are no longer used in dermatology because they refer to nonspecific groups of people. In contrast, "skin of color" may be used - perhaps with further refinements in the future - as a term that relates to skin biology and provides relevant information to dermatologists.

La Isla Rapa Nui se encuentra ubicada en el Océano Pacífico, presentando un clima subtropical oceánico. No existen registros sobre la patología cutánea de la isla. El objetivo del trabajo es establecer la prevalencia y distribución de las patologías cutáneas presentes en la población Rapa Nui. Se realizó un estudio descriptivo transversal con un muestreo por conveniencia, en el hospital Hanga Roa en agosto 2009. La muestra consistió en 131 isleños, 66 por ciento mujeres y 34 por ciento hombres. Los tumores pigmentarios y la patología infecciosa (micosis) fueron las patologías más prevalentes. Cuatro pacientes presentaron queratosis actínicas y otros cuatro carcinomas basocelulares (CBC).
The Easter Island is located in the south pacific, and has a subtropical weather. There are no records about skin diseases in the island. The purpose of this study is to describe the distribution and prevalence of skin diseases in the islanders. A cross sectional study was designed with a convenience sampling at Hanga Roa's Hospital in August 2009. The sampling was 131 islanders, 66 percent women and 34 percent men. Pigmentary tumors and infectious diseases (mycosis) where the most prevalent diseases. Four patients presented actinic keratosis and four basal cell carcinoma (BCC).

Eighty percent of the world`s population consists of individuals with pigmented skin. Darker skin differs from Caucasian skin in its reactivity and disease presentation. The purpose of the study was to see the prevalence of disorders of pigmentation in black Africans of eastern province of Sierra Leone and to compare the differences with other ethnic populations. The study was carried out in eastern province [Kenema] of Sierra Leone from Nov, 2004 to Oct, 2005. It was an observational/descriptive study. Local black patients of all age groups presenting in dermatology out patient department of Pak Field Hospital [established as a part of UN peacekeeping mission in Sierra Leone] were included. After clinical history and physical examination, laboratory investigations were carried out when indicated. Skin diseases were broadly classified into two major categories i.e. pigmentary and non pigmentary. Non-black settlers in the area and UN troops were not included in the study. Data was recorded and analyzed by Microsoft Excel. A total of 3011 patients belonging to different local tribes having a variety of skin disorders were seen during the study period. Patients were of all ages and both sexes ranging from I month to 73 years of age. Sex ratio was almost equal. The pigmentary skin disorders were seen in 228 [7.6%] patients and most prevalent disorders were post inflammatory hyper and hypopigmentation, followed by melasma, vitiligo and albinism. Pigmentary disorders in blacks are not infrequent and can be of significant concern
