[INTRODUCTION - The simultaneous presence of gastric mucosa-associated lymphoid tissue lymphoma (MALT) and a gastrointestinal stromal tumor (GIST) is an extremely rare finding that has not been published until now. CASE REPORT - The authors report on a 78- year-old man who was referred to their department with an emergency upper gastrointestinal bleeding. Urgent gastroscopy revealed a bleeding ulcer in the middle third of the stomach. On the follow-up endoscopy 6 weeks later, an umbilicated polypoid lesion was found proximal to the healed ulcer, which was subsequently removed by elective surgery. Histology and immunohistochemical staining of the specimen for c-Kit confirmed the diagnosis of gastrointestinal stromal tumour. A few weeks later the patient was readmitted because of haematemesis. Upon detailed histological examination of the biopsy specimens taken from the multiple superficial ulcers found near the previous lesion, MALT-lymphoma was diagnosed. The absence of Helicobacter pylori was confirmed by repeated histological examinations, serology and urea breath test. CONCLUSION - This is the first report on a patient with simultaneous presence of a gastrointestinal stromal tumour and gastric mucosaassociated lymphoid tissue lymphoma with H. pylori negativity. Several observations suggest that the development of malignant tumours of the stomach is also associated with H. pylori infection. In view of the reported case, the possibility of a common aetiology of these two neoplasms other than H. pylori infection is discussed.]

[Funcitonal Dyspepsia]


[Functional dyspepsia is defined as a group of different epigastric symptoms without definite morphological, biochemical or infectious origin, having overlapping clinical features. The pathogenesis of the syndrome is surely multi factorial, involving the alterations of visceral perception, as well. Gastric acid hypersecretion does not play an essential role in the development of symptoms, however its pharmacological inhibition may result in symptomatic improvement. Several clinical studies have proved recently that Helicobacter pylori infection has secondary importance in the clinical history of functional dyspepsia patients, nevertheless (in the ulcer-like functional dyspepsia subgroup) eradication therapy is generally accepted as a preventive tool. The dysmotility-type subgroup of the functional dyspepsia syndrome is caused primarily by a multifactorial mixture of gastrointestinal motility disorders and altered visceral perception. The need for positiv diagnosis is emphasized by the authors. The correct doctor-patient relationship plays the most important role in the management of functional dyspepsia patients, complete with a well proven series of acid-inhibitory, prokinetics and anti-anxiety drugs.]

[Helicobacter pylori infection and practical questions of therapy]

RÁCZ István

[According to our knowledge, Helicobacter pylori is a major factor in the pathogenesis of peptic ulcer disease. The prevalence of Helicobacter pylori infection is 70-80% in ulcer patients with the bacteria colonising the mucous surface of the antral mucosa. Eradication therapy against the bacteria leads to complete healing of ulcer disease in about 85-90% of cases. Indications for the eradication and recommended treatment modalities are outlined in several consensus reports; however, in everyday practice a case by case decision is necessary. Present paper summarises two different cases. In the first, the patient has suffered from several relapses of ulcer disease and a successful eradication was performed. Despite of the healing of the ulcer, this patient continued to have prolonged dyspeptic symptoms which called for maintenance antisecretory therapy. The second case is an example that even in a Helicobacter pylori infected patient there could be other reasons for the ulcer pathogenesis. Thorough examinations revealed duodenal manifestation of Crohn’s disease as the background. The message of presented cases is that in each patient individual adaptation of diagnostic and therapeutic algorithms is recommended.]

Late simultaneous carcinomatous meningitis, temporal bone infiltrating macro-metastasis and disseminated multi-organ micro-metastases presenting with mono-symptomatic vertigo – a clinico-pathological case reporT

Although vertigo is one of the most common complaints, intracranial malignant tumors rarely cause sudden asymmetry between the tone of the vestibular peripheries masquerading as a peripheral-like disorder. Here we report a case of simultaneous temporal bone infiltrating macro-metastasis and disseminated multi-organ micro-metastases presenting as acute unilateral vestibular syndrome, due to the reawakening of a primary gastric signet ring cell carcinoma. Purpose – Our objective was to identify those pathophysiological steps that may explain the complex process of tumor reawakening, dissemination. The possible causes of vestibular asymmetry were also traced. A 56-year-old male patient’s interdisciplinary medical data had been retrospectively analyzed. Original clinical and pathological results have been collected and thoroughly reevaluated, then new histological staining and immunohistochemistry methods have been added to the diagnostic pool. During the autopsy the cerebrum and cerebellum was edematous. The apex of the left petrous bone was infiltrated and destructed by a tumor mass of 2x2 cm in size. Histological reexamination of the original gastric resection specimen slides revealed focal submucosal tumorous infiltration with a vascular invasion. By immunohistochemistry mainly single infiltrating tumor cells were observed with Cytokeratin 7 and Vimentin positivity and partial loss of E-cadherin staining. The subsequent histological examination of necropsy tissue specimens confirmed the disseminated, multi-organ microscopic tumorous invasion. Discussion – It has been recently reported that the expression of Vimentin and the loss of E-cadherin is significantly associated with advanced stage, lymph node metastasis, vascular and neural invasion and undifferentiated type with p<0.05 significance. As our patient was middle aged and had no immune-deficiency, the promoting factor of the reawakening of the primary GC malignant disease after a 9-year-long period of dormancy remained undiscovered. The organ-specific tropism explained by the “seed and soil” theory was unexpected, due to rare occurrence of gastric cancer to metastasize in the meninges given that only a minority of these cells would be capable of crossing the blood brain barrier. Patients with past malignancies and new onset of neurological symptoms should alert the physician to central nervous system involvement, and the appropriate, targeted diagnostic and therapeutic work-up should be established immediately. Targeted staining with specific antibodies is recommended. Recent studies on cell lines indicate that metformin strongly inhibits epithelial-mesenchymal transition of gastric cancer cells. Therefore, further studies need to be performed on cases positive for epithelial-mesenchymal transition.
