RESUMEN
El eritema ab igne es una entidad que fue descrita por primera vez por Buschke como hitze melanosis (melanosis inducida por calor), en piernas de personas que trabajaban frente a fuegos abiertos o estufas de carbón. Se define como lesiones cutáneas eritematosas o hiperpigmentadas en un patrón reticulado característico, secundario a la exposición crónica de bajos niveles de radiación infrarroja. A pesar que la aparición de calefacción centralha significado una dramática disminución en su incidencia, aún se describen casos de causa cultural, médica o laboral. Una de susconsecuencias más graves es la posibilidad de aparición de un carcinoma espinocelular sobre la lesión. A continuación se presenta un caso clínico de etiología laboral y se realizará una revisión de la literatura.
Erythema ab igne is an entity that was first described by Buschke as hitze melanosis (heat-induced melanosis), in the legs of people working in front of open fires or coal stoves. It is defined as erythematous or hyperpigmented skin lesions in a reticulated pattern. The main cause is the chronic exposure tolow levels of infrared radiation. Although the occurrence of central heating has meant a dramatic decrease in incidence, cultural, medical or occupational causes are still described. One of the most serious consequences is the possibility of develoging an squamous cell carcinoma. We present a case of occupational aetiology and a review of the literature.

Existe una gran variedad de lesiones o condiciones que producen un cambio de coloración o discromía en la mucosa oral. Entre éstas se encuentran las pigmentaciones que pueden ser de origen exógeno o endógeno y lesiones tumorales. Los pigmentos endógenos incluyen la melanina, hemoglobina, hemosiderina y caroteno. En cambio, las pigmentaciones exógenas se pueden provocar por tatuajes, intoxicación por metales pesados y tinciones.
There are a variety of injuries or conditions that produce a color change or dyschromia in oral mucosa. These dyschromias include pigmentation, that may be of endogenous or exogenous origin and malignant tumor. Endogenous pigments include melanin, hemoglobin, hemosiderin, and carotene. Instead exogenous pigmentation can result from tattoos, heavy metals and stains.

Background: Orofacial clefts are common and have a great medical and social importance. The Latin American Study of Congenital Malformations (ECLAMC), has maintained an epidemiological surveillance of congenital malformations since 1969, allowing the evaluation of trends in the prevalence of malformations. Aim: To evaluate the evolution curve of prevalence rates of orofacial clefts from 1971 to 2008. Material and Methods: All cases of orofacial clefts, occurring in newborns from the maternity of a university hospital from January 2000 to December 2008, were recorded as part of the ECLAMC. Historical information about the rates of the malformation between 1971 and 1999, was obtained from previous manuscripts of the authors. Results: In the study period, 15,635 children were born and 46 had cleft lip-palate (3). This rate is significantly higher than those observed previously, that fuctuated between 1.5 and 1.7. The prevalence rates of cleft lip remained stable from 1971 to 1999 and suffered a brisk and significant rise in the period 2000-2008 When the period is analyzed year by year, the increase in rates is observed in the last two years. The rates of cleft palate suffered a slight non significant rise until 2000. Conclusions: The increased rates of cleft lip palate observed in the last two years of the observation period may be a random result and should be monitored in the future.
