1/5. Dieulafoy's lesion of esophagus.

    Dieulafoy's lesion is a rare arterial malformation that can cause massive gastrointestinal hemorrhage. The lesion occurs most commonly in the proximal stomach. The esophagus is not a common location for this lesion. We present the case of a 25-year-old woman who was admitted to our emergency unit with the findings of hematemesis and melena. Early upper gastrointestinal endoscopic examination revealed a Dieulafoy's lesion, which was located in the distal esophagus. Endoscopic band ligation stopped the bleeding successfully. The patient was discharged 3 days after the band ligation without any complications. Dieulafoy's lesion may cause severe, life-threatening bleeding. Endoscopic diagnosis can be difficult because of the small size and obscure location of the lesion. An abnormally dilated artery that penetrates through the mucosa constitutes the etiology. endoscopy plays an important role in the diagnosis and treatment of this pathology. Despite widespread awareness of this entity, it may present a real challenge for the endoscopist due to the small size and hidden location of the lesion. The endoscopic approach to occult gastrointestinal bleeding for the diagnosis of vascular malformations is accepted as a quick and safe diagnostic method.

3/5. Extramedullary hematopoiesis involving the esophagus in myelofibrosis.

    In this report, we describe a case of myelofibrosis with myeloid metaplasia; a 53-yr-old man was splenectomized for a massively enlarged spleen in which multiple foci of myeloid metaplasia were histologically demonstrated. The patient was referred to us for endoscopic examination, following the repeated occurrence of melena. Upper gastrointestinal endoscopy revealed two active ulcerative lesions in the bulb, and only a moderate erythema in the lower third of the esophagus, which showed no varices. There was no endoscopic evidence of active or recent bleeding. Subsequent histologic examination of biopsies taken from the esophageal lesion surprisingly revealed the presence of hematopoietic tissue.

4/5. Enteric thoracoabdominal duplications in children.

    The clinical and pathological findings of two children with thoracoabdominal enteric duplications are described in detail. In addition, 23 case reports are reviewed. The majority of duplications communicated with the gastrointestinal tract below the diaphragm, but in one case, reported here, the duplication communicated with the cervical esophagus. In infants these duplications most often present with respiratory symptoms, whereas older children more typically have pain and melena. If possible the entire duplication should be removed during one operation.

5/5. Giant pedunculated liposarcomas of the esophagus: literature review and case report.

    Although liposarcoma is the second most common soft-tissue sarcoma in adults, its incidence within the gastrointestinal tract is distinctly low. Esophageal involvement is exceedingly rare and only four cases have been described so far. A fifth case is presented here along with a thorough review of the literature of polypoid lipomatous tumors of the esophagus. Diagnostic and therapeutical strategies of these tumors are discussed in detail.
