A 2 and a half year-old boy with neurofibromatosis developed unilateral proptosis, decreased visual acuity, and optic disk edema. After the discovery and removal of an optic nerve glioma, the patient had ten years of excellent health until he began having headaches, nausea, and
vomiting
. He had papilledema in his remaining eye. At exploration, a cerebellar astrocytoma and a neuroglial
hamartoma
were removed. The occurrence of a glioma of right anterior visual pathway associated with other primary intracranial lesions in patients with neurofibromatosis was not previously reported.

As a causative factor in spontaneous subarachnoid hemorrhage, vascular anomalies, especially aneurysm or arteriovenous malformation, have been generally recognized. On the other hand, subarachnoid hemorrhage from brain tumor and cryptic vascular malformation are rare. We experienced two cases showing subarachnoid hemorrhage from angioblastic meningioma and vascular
hamartoma
as an initial symptom. Case 1: A 48-year-old woman, who complained of severe headache and
vomiting
on Feb. 10th, 1972, gradually became lethargic. Lumbar puncture revealed moderately hemorrhagic C.S.F.. On the fifth day after the onset, she was admitted to our hospital. On admission she showed disorientation and disturbance of resent memory. Aphasia and agnosia were slightly observed. On ophthalmologic examination right homonymous lower quadrant hemianopsia was observed. The carotid angiogram showed slight square shift of the anterior cerebral artery to the right side, elevation of the middle serebral artery and a homogeneous tumor stain in the occipital region in capillary phase. A walnut sized tumor invading the middle portion of the left lateral sinus and showing firm adhesion to the tentrium was found. There was an intracerebral hematoma behined the tumor. The tumor, the tentrium and the lateral sinus were extirpated en bloc and the intracerebral hematoma was aspirated. Histologically, the tumor was angioblastic meningioma. Case 2: A 7-year-old boy, who complained of severe abrupt headache, nuchal pain and
vomiting
on Sept. 17th, 1972, became gradually lethargic. Lumbar puncture revealed hemorrhagic C.S.F., On the tenth day after the onset, he was admitted to our hospital. He showed confusion and agitation. The carotid angiogram showed an unrolling of the pericallosal artery, but no findings of space taking lesions. An air study indicated a globular filling defect protruding into the anterior horn of the right lateral ventricle. The tumor located in the laterobasal wall of the anterior horn was removed picemiel by transventricular approach. Histologically, the tumor was vascular
hamartoma
. Furthermore, we discussed various brain tumors showing subarachnoid hemorrhage as an initial symptom, its frequency and bleeding mechanism on the literature.

Reported in this paper is the case of a female newborn with mesenchymal
hamartoma
of the liver. High-accuracy ultrasonography diagnostics were applied to the mother admitted for examination for suspicion of fetal hydronephrosis in the 31st week of pregnancy. A 7 x 4 cm compartmental process was delineable in the abdominal region of the foetus and was variably viewed in ultrasonography in cystic or solid form. A girl, 2,650 g in body weight and 47 cm in body length, was delivered by caesarean section in the 35th week of pregnancy. Postnatal nutritional disorders were accompanied with recurrent
vomiting
. Sonography, computed tomography and scintigraphy were performed, and the prenatally diagnosed process was identified as a cystic growth in the right liver lobe with enclosure of the V. cava inferior. A typical hepatolobectomy was performed on the newborn on her 15th day of age, with the V. cava enclosing part being left unextirpated. Mesenchymal hamartoma of the liver was the histological diagnosis. Only one prenatally diagnosed case of this kind had been known from literature before.

Among 100 childhood brain tumors treated at Kobe Children's Hospital from May 1970 to June 1985, 18 of the children presented with symptoms during the first year of life. This paper analyzes these 18 cases. Supratentorial tumors (78%) were more common than infratentorial ones, and 67% of all the tumors were located in the central neural axis. Initial symptoms were cranial enlargement (56%),
vomiting
(17%), cranial deformity (11%), blepharoptosis, respiratory distress, and ataxia. Histological diagnosis of the tumors was as follows: teratoma (3 cases), medulloblastoma (3), glioblastoma (2), astrocytoma (2), ependymoma (2), craniopharyngioma (1), choroid plexus papilloma (1),
hamartoma
(1), lipoma (1), melanotic progonoma (1), and an undetermined type, probably medulloblastoma (1). Seventeen of the patients underwent craniotomy for tumor resection (4 total, 4 subtotal and 7 partial removal, and 2 biopsies). Additional therapeutic methods used separately and in various combinations included ventriculoperitoneal shunt, subduralperitoneal shunt, ventricular drainage, radiotherapy and chemotherapy. Nine patients died (average 98 days) after surgery. Of the 9 survivors, 6 are still alive after more than 5 years. Five of the 6 are mentally retarded and 4 are physically handicapped to some degree.

The literature concerning gastric tumors in children is mainly limited to case studies. The authors reviewed 1,403 histological reports of pediatric gastric pathology (covering 10 years) at their institution. There were three gastric tumors of benign histology and no malignant tumors. The first patient was a 9 1/2-year-old boy who presented with several months of symptomatic, pH-probe-confirmed gastroesophageal reflux. He underwent placement of a Toupet antireflux valve. During laparotomy, a submucosal mass was discovered incidentally, on the greater curvature of the stomach. The mass was excised. Pathological examination showed heterotopic pancreas. The second patient, a 15-month-old girl, presented with a short period of
vomiting
. Results of an upper gastrointestinal series showed gastric outlet obstruction. She underwent laparotomy and was found to have an intussusception of a gastric polyp into the proximal jejunum, and an associated malrotation. Ladd's procedure, gastroduoduodenostomy with reduction of the intussuscepted polyp, and excision of the polyp were performed. Histological examination of the tumor showed
hamartoma
with hyperplastic elements. The tumor was benign but was regarded as difficult to classify. The third patient, a 6-year-old boy, presented with microcytic anemia. Endoscopy showed multiple friable bleeding gastric masses. He underwent laparotomy, with partial gastrectomy and pyloroplasty. Histological examination showed the tumor to be plasma cell granuloma. The tumor recurred, and the patient required subsequent operative procedures. The authors confirm that gastric tumors in children are rare. Although the tumor histology may be benign, excision of the tumor may require major operative resection.

A rare case of myoepithelial
hamartoma
of the duodenal wall is presented, and previous case reports found in the literature are reviewed. Myoepithelial hamartomas are thought to arise from displaced pancreatic anlage present along the gastrointestinal tract during embryogenesis, which can differentiate into various pancreatic elements; the most highly differentiated form is heterotopic pancreas. An alternative theory is pancreatic metaplasia of endodermal tissues. We describe a 41-year-old man who presented with abdominal pain and
vomiting
. CT scanning revealed a mass at the head of the pancreas. A pancreaticoduodenectomy was performed for presumed cystadenoma. Histology of the mass revealed a disorderly arrangement of smooth muscle, dilated and nondilated ducts, pancreatic acinar tissue and mucus glands. The relationship of myoepithelial hamartomas involving the small bowel to similar lesions in the stomach, bile ducts and gallbladder is discussed.

Gastrointestinal haemangiomas make up 0.05% of all intestinal neoplasms. They are sometimes multiple and usually present with pain, bleeding, and obstruction. An associated haemangiomatous change in regional lymph nodes has not been reported previously. A woman of 21 years presented with abdominal pain and
vomiting
. Abdominal ultrasound and computed tomography scan showed a lower abdominal mass. Laparotomy revealed a small bowel tumour causing an intussusception together with enlarged mesenteric lymph nodes. Pathological examination revealed a small bowel haemangioma with mesenteric node involvement. The pathogenesis of haemangiomatous involvement of lymph nodes is discussed.
Hamartomatous
change is the likely cause in this patient.

We present the case of a 50-year old patient, operated on for three adjoining annular strictures in the jejunum with proximal dilatation. He presented with a one-year history of recurrent cramping in the upper abdomen and
vomiting
, with two episodes of intestinal obstruction. Microscopic examination of the stricture revealed, in the submucosa, disorganised fascicles of smooth muscle derived from the muscularis mucosae, bundles of non-myelinated nerve fibres with scattered abnormal ganglion cells and haemangiomatous vessels. The pathological findings observed were similar to those described as neuromuscular and vascular
hamartoma
, a rare stricturing condition of the small intestine. Many authors have questioned the hamartomatous nature of this disorder, since identical features may be seen in Crohn's disease, in ischaemic enteritis, in radiation enteritis and in non-steroidal antiinflammatory drug-induced small intestinal strictures. On the basis of a review of the 5 previously described cases and of our own experience, we believe that neuro muscular and vascular
hamartoma
of the small bowel should be considered as a distinct entity if histological hallmarks of Crohn's disease are absent, in patients with no history of gastrointestinal disease, or of chronic ingestion of non-steroidal antiinflammatory drugs.

Heterotopic pancreas, usually a silent gastrointestinal malformation, may become clinically evident when complicated by chronic inflammation. We report a case of pancreatitis and extensive pseudocyst formation in the gastric antrum, which caused gastric outlet obstruction. The diagnosis was obscured by a history of
emesis
during pregnancy and a previously resected gastric polyp. The nature of the obstructive lesion was not diagnosed preoperatively in spite of endosonographic evaluation. Intraoperatively, a cystic tumor of the stomach wall was found, the lesion was excised, and a pyloroplasty was performed to close the excision site. Histology revealed heterotopic pancreatic tissue with chronic inflammation, fibrosis and pseudocyst formation and adjacent to this lesion a myoglandular
hamartoma
. The patient is symptom-free two years after surgery and no recurrence was found. The nature of heterotopic pancreatic tissue, its diagnosis and management are discussed.

A 12-year-old boy visited our hospital with complaints of severe upper abdominal pain and
vomiting
. Marked tenderness was present in the upper abdomen, and a movable hard tumor the size of a fist was felt there. Because abdominal computed tomography scans revealed invagination, an emergency laparotomy was performed. The small intestine was invaginated over an area measuring 30 cm in length. After the invaginated intestine was restored, a mass was felt in the small intestine, which was resected over an area measuring approximately 10 cm in length. The extracted mass was histopathologically found to be a
hamartoma
. The patient was diagnosed to have Peutz-Jeghers syndrome (PJS) based on the presence of pigmented spots detected on the oral cavity, lips, and toes of both feet. PJS is an autosomal dominant genetic disease associated with melanin pigment spots on the oral mucosa, lips, nasal alae, palm, and soles, as well as hamartomatous polyposis in the alimentary canal. Polyps are often a cause of invagination and ileus in affected patients. Gastrointestinal cancer, uterine cancer, and breast cancer are also seen in patients with PJS. A long-term follow-up is required to prevent invagination and ileus in children and cancer in adults.
