The United States of America (USA or U.S.A.), commonly called the United States (US or U.S.) or America, is a federal republic consisting of fifty states and a federal district [1]. At 3.79 million square miles (9.83 million km2) and with around 315 million people, the United States is the third- or fourth-largest country by total area and the third-largest by both land area and population [1]. The U.S. is a global leader in medical innovation. America solely developed or contributed significantly to 9 of the top 10 most important medical innovations since 1975 as ranked by a 2001 poll of physicians,. Since 1966 Americans have received more Nobel Prizes in Medicine than the rest of the world combined [1]. Large numbers of the eponyms we use currently, in dermatology are originated from USA, and many new conditions in dermatology are being named after scientists from USA...

Latin America refers to territories in America where the Spanish or Portuguese languages prevail: Mexico, most of Central and South America, and in the Caribbean, Cuba, the Dominican Republic, and Puerto Rico – in summary, Hispanic America and Brazil [1]. By this definition, Latin America is coterminous with Ibero-america („Iberian America”) [1].

Many medical conditions derive their names from either Greek or Latin. In this manuscript, we are reviewing, some selected examples of eponyms, in dermatology literature, linked to the Latin America (Tabl. I) [2-14]. We want also to point out that many scientists in other parts of the world and particularly in USA, for whom medical diseases were eponymously named, were originated from latin America. Just an example is, Bannayan–Riley–Ruvalcaba syndrome (BRRS), which is a dominant autosomal disorder characterized by cutaneous lipomas, macrocephaly, intestinal polyps, and developmental delay [15]. It is named after American physicians. One of them, Rogelio H. Ruvalcaba (born in 1934) received his MD degree from the Universidad de Guadalajara, in Mexico and immigrated to USA...

Russia, also officially known as the Russian Federation. At 17,075,400 square kilometres, Russia is the largest country in the world, covering more than one-eighth of the Earth’s inhabited land area. Russia is also the world’s ninth most populous nation with 143 million people as of 2012 [1]. The Russian economy is one of the world’s fastest growing. Its extensive mineral and energy resources, the largest reserves in the world, have made it one of the largest producer of oil and natural gas globally. It is a great power and a permanent member of the United Nations Security Council [1]....
