QUIROS ALPIZAR, José Luis  and  ALPIZAR MIRANDA, Kattia E. Quimerismo genético un nuevo paradigma para la medicina legal. Med. leg. Costa Rica [online]. 2009, vol.26, n.2, pp.73-78. ISSN 2215-5287.

Genetic chimerism is a not well defined concept among the scientific community; it is still confused with mosaicism. In the following review we intend to define the concept with a legal point of view and exemplify it with a series of cases described in medical texts. The cases lead us to find the clear difference between mosaicism and chimerism. Contained in these series of cases we have separated the ones related with hemaphroditism from the ones that are not related. We also make reference to a new concept that generates controversy in the investigation; microchimerism, which is related with blood transfusions, transplants and genesis of autoimmune diseases..

Keywords : Chimerism; microchimerism; mosaicism; hemaphroditism.
