672 Possible Causes for Hematemesis, Rarely Malignant

  • Leiomyosarcoma

    In conclusion, primary pancreatic leiomyosarcoma is a rare and highly malignant tumor associated with poor prognosis.[] The tumors may cause bleeding in the gastrointestinal tract and cause black, tarry, foul-smelling stools (melena), or vomiting of blood (hematemesis) or abdominal discomforts[] Leiomyosarcomas (LMS) are rare sinonasal malignant tumours with 20 cases of nasal LMS previously reported in the literature.[]

  • Esophagitis

    Because cancer only rarely occurs in the pediatric age group (10), that issue is discussed elsewhere (7,11).[] A 52-yr-old man was admitted to the hospital with severe hematemesis and syncope.[] Patients often present with retrosternal pain, odynophagia, and dysphagia, with abdominal pain and hematemesis being uncommon symptoms.[]

  • Liposarcoma

    Mediastinal liposarcoma is an extremely rare malignancy with a poor prognosis. We report the case of a 73-year-old man who presented with severe respiratory distress.[] She had sometimes noticed tarry stools since her first episode of hematemesis 1 year earlier.[] Liposarcoma is a rare malignant mesenchymal tumour. Very few cases of retropharyngeal liposarcoma have been reported in the literature.[]

  • Duodenal Ulcer

    Abstract Malignant degeneration of a chronic peptic duodenal ulcer is rarely observed, as compared with malignant changes in a peptic ulcer of the stomach.[] The authors present the case of a 5-y-old boy having hematemesis, gastric outlet obstruction and multiple duodenal ulcers.[] The malignant degeneration of gastric ulcers appears to be rare. 2,8,31,32 Tumors that are chemically induced in rodents tend to develop in or near ulcers, but the presence[]

  • Gastric Ulcer

    Persistence of symptoms post-PPI therapy should lead the clinician to suspect failure of H. pylori eradication, malignancy, or rare causes such as Zollinger-Ellison Syndrome[] We report the case of a 67 year old male who presented with a nine year history of a gastric ulcer with symptoms of hematemesis and melena.[] Could my duodenal ulcer possibly be a malignancy? No. Duodenal cancer is very rare and does not resemble duodenal cancer at all.[]

  • Gastrointestinal Hemorrhage

    Interestingly, although strongyloidiasis is common among AIDS patients in endemic areas, the hyperinfection syndrome is rarely noted.[] […] without hematemesis or coffee ground emesis could be separated out).[] Heterotopic pancreas is a rare congenital anomaly and usually discovered incidentally.[]

  • Upper Gastrointestinal Bleeding

    Mallory-Weiss tear Vascular malformation Rare causes include: Dieulafoy's lesion (a vascular malformation of the proximal stomach).[] In patients with gastrointestinal (GI) tract bleeding, the bleeding source is uncertain in the absence of hematemesis.[] All of the emergency department visits by children ages 0 to 18 years who presented with hematemesis between 2000 and 2007 were reviewed.[]

  • Thrombocytopenia

    Rituximab-induced acute thrombocytopenia is a rare side effect that has previously been reported in a small number of patients with malignant lymphoma; its mechanism is still[] Surgical excision is the main treatment of this highly malignant disease.[] RATIONALE: Primary splenic angiosarcoma (PSA) is a rare, fatal neoplasm originating from sinusoidal vascular endothelial cells, and usually metastasizes and almost always[]

  • Gastric Leiomyosarcoma

    The difficulties in the preoperative diagnosis of this rare malignancy are discussed.[] We present here a rare case of gastric leiomyosarcoma revealed by a massive hematemesis in a young woman.[] Leiomyosarcomas (LMS) are extremely rare malignant neoplasms that originate from smooth muscle cells and may be considered the malignant counterpart of a leiomyoma.[]

  • Liver Cirrhosis

    (10%), heart failure (3%), tuberculosis (2%), pancreatitis (1%), and other rare causes. 6 The true prevalence and incidence of cirrhosis of the liver and its complications[] The child presented with complaints of malena, hematemesis and variceal bleed.[] We are of the opinion that airway protection at emergency endoscopy is extremely important in patients with suspected variceal bleeding, who present with hematemesis, and[]
