Los albinos tienen predisposición al padecimiento de determinados tipos de cáncer cutáneo, pero el melanoma no es común. Entre los pocos artículos que documentan su aparición en estos pacientes, la afección gastrointestinal por melanoma aparece con relativa frecuencia, ya sea en forma de tumor primario o metástasis. Se presenta el caso de una paciente mujer de 70 años con una lesión gástrica y otra intestinal, detectadas mediante tomografía computada.

Albinos are predisposed to suffer certain types of skin cancer, but not usually melanoma, with just a few reports documenting it .Gastrointestinal tract is a relatively frequent site of melanoma occurrence, weather as a primary tumour or metastasis. We report a case of a 70 year-old female patient who underwent a computed tomography where a gastric and a bowel tumor were found. The pathology study was compatible with the diagnosis of an amelanotic melanoma. Despite that the diagnosis of melanoma in albine patients is a rare finding, it must be considered. It is also important to search through the digestive system even if there is no primary melanoma known.(AU)
ABSTRACT
OBJECTIVE: Coffee is a beverage used worldwide. It includes a wide array of components that can have potential implication on health. We have reviewed publications on the impact of coffee on a series of health outcomes. METHODS: Articles published between January 1990 and December 2012 were selected after crossing coffee or caffeine with a list of keywords representative of the most relevant health areas potentially affected by coffee intake. RESULTS: Caffeine, chlorogenic acids and diterpenes are important components of coffee. Tolerance often acts as a modulator of the biological actions of coffee. There is a significant impact of coffee on the cardiovascular system, and on the metabolism of carbohydrates and lipids. Contrary to previous beliefs, the various forms of arterial cardiovascular disease, arrhythmia or heart insufficiency seem unaffected by coffee intake. Coffee is associated with a reduction in the incidence of diabetes and liver disease. Protection seems to exist also for Parkinson's disease among the neurological disorders, while its potential as an osteoporosis risk factor is under debate. Its effect on cancer risk depends on the tissue concerned, although it appears to favor risk reduction. Coffee consumption seems to reduce mortality. CONCLUSION: The information gathered in recent years has generated a new concept of coffee, one which does not match the common belief that coffee is mostly harmful. This view is further supported by the discovery of a series of phyto-components with a beneficial profile. Reasonable optimism needs to be tempered, however, by the insufficiency of the clinical data, which in most cases stem from observational studies.
