The authors describe 9 cases of primitive tumors of the small gut (3 adenocarcinomas, 2 lymphosarcomas, 1 fibroma, 1 angioma, and 2 leiomyosarcomas, one being the cause of active hemorrhage). In all cases the tumors were diagnosed only at operation, which was invariably necessitated by complications. Seven patients underwent emergency surgery for intestinal obstruction; one underwent an exploratory laparotomy for recurrent intestinal bleeding caused by an angioma of the ileum; and the last of this series (exceptional enough to warrant separate reporting elsewhere) was operated upon as an emergency case when the tumor, precisely a leiomyosarcoma, was perforated and actively bleeding.

A rare case of solitary intussuscepting capillary hemangioma in the distal ileum with perforation and peritonitis is presented. The diagnosis was made only at surgery for presumed acute intestinal obstruction.

Retroperitoneal soft-tissue tumors are rare in infancy. In this report, we describe a distinctive hemangioendothelioma occurring in the retroperitoneum of a 10-month-old baby girl. This lesion was complicated by obstructive jaundice, intestinal obstruction, and thrombocytopenia (Kasabach-Merritt syndrome) leading to intracranial hemorrhage. The microscopic features of this tumor, characterized by infiltrative lobules of spindle cells and capillaries, are distinct from those of other well-recognized vasoformative tumors. In some areas, the tumor shows a striking resemblance to Kaposi's sarcoma; criss-crossing fascicles of spindle cells are interspersed with narrow vascular spaces, but PAS-positive hyaline globules are absent. The tumor can also be distinguished from the cellular hemangioma of childhood by its well-formed spindle cell fascicles. Several histologically similar cases have been reported. All of them occurred in the retroperitoneum of infants and were frequently complicated by Kasabach-Merritt syndrome. We therefore propose the designation "Kaposi-like infantile hemangioendothelioma" for this unusual neoplasm.

The Blue Rubber Bleb Nevus syndrome is a rare disease characterized by a distinctive type of hemangioma which involves the skin and the gastrointestinal tract. In the latter location, these lesions are often responsible for chronic blood loss and secondary anemia, and in rare situations may act as a leading point for an intussusception. The diagnosis of intussusception in children older than 3 or 4 yr is frequently difficult and delayed. In a child with typical skin lesions of the Blue Rubber Bleb Nevus syndrome, an acute illness with manifestations of intestinal obstruction should indicate the possibility of an associated intussusception.

The spleen in newborns, infants, and children is rarely involved in a variety of pathological processes. These processes may involve an isolated splenic disease or may be a part of a systemic illness. Renal vein thrombosis in infants of diabetic mothers has been reported. We report a case of a newborn with intestinal obstruction caused by an infarcted splenic hemangioma and renal vein thrombosis. To the best of our knowledge, this is the youngest case with both above-mentioned diagnoses and causes of intestinal obstruction in the English medical literature.

A 20-year-old man presented with acute intestinal obstruction due to multiple hemangiomas of small intestine extending into the adjoining mesentery. The diagnosis was made at laparotomy and subsequently confirmed on histology. Occurrence of hemangioma in the small intestine and its presentation as acute intestinal obstruction are rare.

Colon and rectum hemangioma is a rare disease, and even more so when it presents as cavernous subtype; few of these hemangioma have been confirmed by pathology reports. The main presentation of this disease is observed by transrectal painless bleeding; other manifestations are less frequent. Diagnosis implies high index of suspicion and proper diagnostic workup; this entity has been frequently misdiagnosed as other more common entities. We present the case of a 15-year-old female patient with a cavernous hemangioma of the sigmoid colon; her principal complaint was abdominal pain. Diagnosis was suspected due to the finding of phleboliths in plain abdominal film and diagnostic findings in colonoscopy. The patient was treated by means of segmental resection of the colon and experienced a satisfactory postoperatory recovery. According to the literature, these hemangiomas originate from embryologic sequestrations of mesodermal tissue, while clinically they usually present between the ages of 5 and 25 years, most commonly with painless transrectal bleeding and less frequently with intestinal obstruction, tenesmus, urgency, abdominal pain or mass, and anemia. The majority of these hemangiomas are localized in rectosigmoid region of the colon and may infiltrate surrounding tissues; 26-50% show phleboliths in plain abdominal film. Colonoscopy is considered by many authors the best diagnostic tool; angiography, computed tomography (CT) scan and scintigraphy may be also useful. The only effective treatment of this disease is complete surgical resection, for which there have been many proposals regarding best method and approach.

Colon hemangiomas are rare benign vascular lesions which are usually seen in teenagers. The frequent presentation is repetitive painless rectal bleeding. Colonic hemangiomas are occasionally found in the rectosigmoid area. A 62-year-old male patient was admitted to the hospital with the complaints of mechanical bowel obstruction. The radiological imaging techniques revealed a transverse colon tumor. Consequently, the patient was operated, and transverse colectomy and end-to-end anastomosis were performed. No postoperative complications occurred. The pathologic examination revealed cavernous hemangioma of the transverse colon. This report describes a very rare case of bowel obstruction due to colonic hemangioma.

Pyogenic granuloma (PG), also known as lobular capillary hemangioma, is a benign vascular tumor, most commonly arising on the skin and the oral mucosa. Gastrointestinal localization of PG, except for the oral cavity, is exceptionally rare. We describe a case of ileal PG occurring in a 13-year-old girl, presenting with intestinal obstruction. Histological examination revealed proliferation of capillary-sized vessels, with prominent intravascular component, involving the entire thickness of the intestinal wall. Immunohistochemistry showed positivity for CD31, CD34 and von Willebrand factor, whereas immunostaining for glucose transporter-1 protein (GLUT1) and for human herpes virus 8 (HHV-8) was negative. We suggest that PG should be considered in the differential diagnosis of childhood gastrointestinal polypoid lesions.

We present the extremely rare case of a male newborn with Beckwith-Wiedemann Syndrome (BWS) presenting as delayed abdominal wall closure and neonatal intussusception. Fetal ultrasound had shown omphalocele that resolved spontaneously. When feeding was attempted, he had various episodes of vomiting. An x-ray showed signs of high bowel obstruction. Jejunal intussusception was found on laparotomy. Enterectomy and primary jejuno-jejunal anastomosis was performed. During post-operative period subtle physical findings became prominent: plain hemangioma, posterior helical indentations, and macroglossia. Cardiac ultrasonography showed a patent foramen oval with small left-to-right shunt. Ultrasonography showed renal hyperplasia. Genetic study showed hypomethylation of DMR2 region of 11p15 chromosome.
