ABSTRACT
ABSTRACT The gastrointestinal stromal tumors (GIST) are rare and consist in mesenchymal neoplasms of the gastrointestinal tract, which may affect any part of the gastrointestinal tract, and is more frequent in stomach. We report a case of a 65-years-old male patient who presented a mass in the proximal ileum found by exploratory laparotomy. The patient underwent a segmental enterectomy with total resection of the tumor and free surgical margins with the pathological diagnosis of GIST, confirmed by immunohistochemistry (CD117).
RESUMEN Los tumores del estroma gastrointestinal (GIST) son raros, consisten en neoplasias de origen mesodérmico del tracto gastrointestinal y pueden acometer cualquier parte del tracto gastrointestinal, siendo más frecuentes en el estómago. Reportamos el caso de un paciente varón, de 65 años de edad, con una masa en el íleon proximal, descubierta mediante laparotomía exploratoria. Se ha realizado una enterectomía segmentaria, con la resección total del tumor y márgenes quirúrgicos libres. El diagnóstico anatomopatológico de GIST fue confirmado por inmunohistoquímica (CD117).
RESUMO Os tumores estromais gastrointestinais (GISTs) são raros, consistem em neoplasias mesenquimais do trato gastrointestinal e podem acometer qualquer parte do trato gastrointestinal, sendo mais frequentes no estômago. Relatamos o caso de um paciente do sexo masculino, 65 anos de idade, com uma massa em íleo proximal, descoberta em uma laparotomia exploradora. Foi realizada enterectomia segmentar com ressecção total do tumor e margens cirúrgicas livres, com o diagnóstico anatomopatológico de GIST confirmado por imuno-histoquímica (CD117).
ABSTRACT
Objective To summarize the clinical characteristics and diagnosis and treatment of hemangioma of small intestine in children.Methods Location,pathology,clinical manifestation,diagnosis and treatment of 3 cases from our hospital and 44 cases reported in our courtry with hemangioma of the small bowel were analyzed from 1994 to 2004.Results These tumors locating in jejunum,ileum,duodenum as well as parts small intestine were 31.9%,42.6%,4.2% and 21.3%,respectively.Solitary and multiple tumors were 29.8% and 70.2% separately.The histopatholical report of 10 cases revealed that capillary,cavernous,mixed type hemangioma and hematolymphangioma were 2,6,1 and 1 cases,respectively.Thirty nine children presented with recurrent black stool.Five patients manifest in the form of intussusception.One child passed a bloody stool so massive as to cause shock.Small-bowel obstruction occurred in 5 cases.The hemoglobin of 38 patients were lower than 90 g/L.The incidence of preoperative diagnosis was only 10.6%.All of patients were performed operation.Conclusions The frequent locations of hemangioma of small intestine are in ileum and jejunum,and multiple tumors are common.The diseases are characterized as recurrent hematochezia with painlessness.Preoperative diagnosis of a small bowel hemangioma can be very difficult.The segments of small bowel with hemangioma resection are the most method of the treatment.
