We report a case of a 62-year-old man known to have lung adenocarcinoma poorly differentiated presented with melena 1 month after diagnosis. Upper endoscopy revealed an ulcerated tumor in the prepyloric antrum. The diagnosis of gastric metastasis from pulmonary cancer was confirmed by the immunohistochemical staining for the thyroid transcriptional factor-1 and the pattern cytokeratine CK7+/CK20-. In conclusion, gastric metastasis from primary lung cancer is a rare phenomenon that every clinician must keep in mind.

However, diagnosis must be considered early in cirrhotic patients with hematic ascites as a delayed diagnosis with hemodynamic instability is associated with a poor prognosis. Case report: We present the case of a 54-year-old cirrhotic patient who presented a spontaneous hemoperitoneum due to the rupture of the intra-abdominal vein that was diagnosed during exploratory laparoscopy. Conclusion: Early diagnosis and management of spontaneous hemoperitoneum due to the rupture of intra-abdominal vein helps improve its prognosis.

Thus far, no particular risk factors have been identified. We present a case of synchronous multiple primary cancers of the stomach and kidney in a 67-year-old female presenting with a 3-month history of vomiting and abdominal pain. The diagnosis of gastric adenocarcinoma with signet ring cells was confirmed through upper endoscopy with biopsies, while CT-guided biopsies of the renal tumor confirmed the diagnosis of primary kidney neoplasm.

Clinical, radiological and endoscopic features are nonspecific. The diagnosis must be considered in front of chronic abdominal pain, vesperal fever and weight loss with on colonoscopy the presence of nodules or ulcers. The diagnosis is made on pathological findings. Case report: We report a case of an 82-year-old female patient with the diagnosis of colonic tuberculosis. The diagnosis were suspected on clinical presentation: chronic abdominal pain, fever and weight loss. The colonoscopy showed a nodular aspect of the left and sigmoid colonic mucosa and the pathology examination of the multiple biopsy specimens showed an epithelioid and gigantocellular granulomas with caseous necrosis. Conclusion: In front of a nonspecific clinical and endoscopic aspects, multiples colonic biopsies are mandatory to rule out differential diagnosis and confirm colonic tuberculosis.

Its manifestations are numerous and they mainly include skeletal and dental deformities, cranial nerve entrapment and infections. Over time, osteoclastic expansion invades bone marrow leaving little space for hematopoietic cells. As a result, extramedullary hematopoiesis takes place in the reticular system mainly in the spleen and liver. In these patients, portal hypertension can occur as a result of extramedullary hematopoiesis associated splenomegaly. We are reporting in this article a rare case of spontaneous bacterial peritonitis associated with portal hypertension in a patient with osteopetrosis.

Gastric metastasis from colonic cancer is exceptional. We hereby report a case of a 54-year-old male patient who underwent a right hemicolectomy for right-sided colon cancer. The pathology exam revealed well differentiated adenocarcinoma, it was classified stage IIb. Regular controls performed including colonoscopy were normal. Four years after colectomy, the patient was admitted for hematemesis with epigastric pain with detoriation of general condition . Gastroscopy revealed a large ulceroproliferative mass in the antropyloric region. Histology showed that this tumor was an adenocarcinoma similar to the primary right colon cancer, which led to the diagnosis of metastatic gastric cancer originating from colon cancer.

LSII is an extracolonic cancer syndrome characterized by a tumor spectrum including gastric cancer (GC). In the current work, our main aim was to identify the mutational spectrum underlying the genetic predisposition to diffuse gastric tumors occurring in a Tunisian family suspected of both HDGC and LS II syndromes. We selected the index case “JI-021”, which was a woman diagnosed with a Diffuse Gastric Carcinoma and fulfilling the international guidelines for both HDGC and LSII syndromes. For DNA repair, a custom panel targeting 87 candidate genes recovering the four DNA repair pathways was used. Structural bioinformatics analysis was conducted to predict the effect of the revealed variants on the functional properties of the proteins. DNA repair genes panel screening identified two variants: a rare MSH2 c.728G&g...

The majority of leech attachments are external and short-lasting. Internal surfaces can be involved. Yet, esophageal attachment is very rare. We report a case of a 59-year-old female who presented with hematemesis, melena and chest pain. Upper gastrointestinal endoscopy revealed a round black foreign body in the mid-third of the esophagus identified as a leech. We carefully extracted the worm with a forceps applied to the middle of its body. The diagnosis of leech infestation should be kept in mind when exploring gastrointestinal bleeding in patients living in rural areas and those with poor living conditions.

The EncephalApp Stroop test is validated for its screening. The aim of the study was to define Tunisian norms for the test based on healthy controls norms and to estimate the prevalence of CHE in cirrhotic Tunisian patients. Methods: A prospective, multicenter, cross‐sectional study was conducted. Ambulatory or hospitalized cirrhotic patients aged 40 years and over were recruited at 11 centers. Healthy subjects aged 40 years and over were recruited at 8 centers. We used a translated Arabic version of the streamlined EncephalApp Stroop test. The task has two components: “Off” and “On” state depending on the discordance or concordance of the stimuli. Results: 142 patients were included. The mean age was 57.26 years [40–86]. 40 (28.17%) of cirrhotic patients who were included were diagnosed as having a minimal hepatic encephalopathy or CHE. Among the ineligible patients, 22 had overt hepatic e...
