2013
A mucosa gastrica heterotopica (MGH) e uma entidade rara, com malignizacao incomum, descrita em todo o trato gastrointestinal e fora dele. O relato e de uma mulher de 37 anos, com queixa de dor epigastrica associada a vomitos pos-prandiais com tres meses de evolucao, causado por MGH localizada na quarta porcao duodenal. Submetida a resseccao do seguimento acometido, encontra-se em acompanhamento sem queixas ou sinais de recidiva. A MGH deve ser lembrada como um diagnostico diferencial nos sangramentos e obstrucoes duodenais; a resseccao endoscopica ou cirurgica, se factivel, deve ser realizada com o intuito terapeutico.(AU) The heterotopic gastric mucosa (HGM) is a rare event, with uncommon malignant, described throughout the gastrointestinal tract and beyond. The report is about a 37 years-old female, with epigastric pain associated with postprandial vomiting with three months of evolution, caused by HGM located in the fourth portion of the duodenum. The patient underwent resection of the affected segment and since then there has been no complaints or signs of recurrence. The HGM should be remembered as a differential diagnosis in bleeding and duodenal obstruction. The endoscopic or surgical resection, if feasible, should be performed with therapeutic purposes.(AU)
