Gastric metastasis and peritoneal carcinosis revealing primary breast cancer: an unusual presentation.

Breast cancer is the most frequent cancer among women. Gastrointestinal tract metastases are uncommon and might be misidentified as primary carcinoma.A noteworthy case-study involved 53-year-old-woman complaining from epigastric pain, ascites and overall health decline. Initial investigations were inconclusive, prompting laparoscopic peritoneal biopsies which revealed independent cell proliferation. Subsequently, a second look upper digestive endoscopy showed multiple gastric ulcerations suggestive of gastric carcinoma. Histologic examination confirmed independent cell proliferation with estrogen receptors expression, a characteristic feature of breast carcinoma. Further investigations led to bilateral invasive lobular breast carcinoma diagnosis. Epirubicin cycophosphamide was prescribed after progression under letrozole ribocilib therapy.This case aims to raise awareness among clinicians about the importance of ruling out breast cancer in patients with peritoneal carcinosis and paying attention to digestive symptoms in breast cancer patients with careful gastric endoscopic examination to avoid misdiagnosis.

Guillain-Barré syndrome in ulcerative colitis and SARS-CoV-2 infection: a case report and literature review.

Aim: Guillain-Barré syndrome (GBS) occurrence is rare during inflammatory bowel disease (IBD) and SARS-CoV-2 infection. Its association with thrombotic vascular events, which are common during these two entities, is extremely rare. Case report: We report an exceptional association of GBS and cerebral venous thrombosis in a 28-year-old woman with active ulcerative colitis and no previous history of SARS-CoV-2 vaccination. Mildly symptomatic SARS-CoV-2 infection was diagnosed during etiological investigations of cerebral venous thrombosis. GBS symptoms began 10 days later with clinical and electrical abnormalities consistent with axonal GBS. Other GBS causes were excluded. Favorable outcomes were noted after intravenous immunoglobulin perfusion with full recovery 12 months later. Conclusion: Greater attention should be focused on IBD patients with SARS-CoV-2 infection regardless of its severity.

Guillain Barré Syndrome (GBS) is a rare disorder in which the immune system attacks one's own nerves. This is responsible for progressive muscle weakness and in severe cases paralysis until death. The association of vascular issues with GBS is rare, occurring in specific situations such as inflammatory bowel diseases or SARS-CoV-2 infections. Herein, we report an exceptional association of cerebral thrombosis and GBS, in a young female patient with ulcerative colitis and a mildly symptomatic SARS-CoV-2 infection, that was responsible for a gait disorder. Significant improvement was noted following immunoglobulin infusion and physical rehabilitation, with full recovery 12 months after treatment. Greater attention should be directed toward patients with SARS-CoV-2 infection regardless of its severity.

Rare but concerning: young ulcerative colitis patient developed Guillain Barré Syndrome & venous thrombosis post mild SARS-CoV-2 infection. Even benign COVID-19 cases can be deadly in some. #COVID19 #HealthComplications #IBD #LifeThreatening.

Gastrosplenic fistula due to splenic lymphoma: two case reports and review of the literature.

BACKGROUND: Gastrosplenic fistula is a rare and potentially fatal complication of various conditions. Lymphoma is the most common cause. It can occur spontaneously or after chemotherapy. Gastrosplenic fistula diagnosis can be confused with a splenic abscess because of the presence of air into the mass. The computed tomography identification of the fistulous tract is the key to a right diagnosis. Treatment modalities include surgical resection, chemotherapy, or a combination of both. CASE PRESENTATION: Here we report two patients with gastrosplenic fistula due to diffuse large B cell lymphoma. The first patient was a 54-year-old Caucasian woman with an enormous primary splenic diffuse large B cell lymphoma leading to the development of a spontaneous fistula in the stomach. The second patient was a 48-year-old Caucasian male patient with an enormous splenic diffuse large B cell lymphoma complicated by fistula after chemotherapy. Both patients died of septic shock several days after surgery. CONCLUSION: Gastrosplenic fistula is a rare complication with a poor-prognosis, for which surgery is currently the preferred treatment.

Mesenteric Arterial Thrombosis Revealing Relapse of Nephrotic Syndrome in Young Women.

Background: Nephrotic syndrome (NS) is associated with a hypercoagulable state and may be complicated by thrombotic events. Venous thrombosis is well-acknowledged, while arterial thrombosis is rather unusual. Case Presentation: We present the case of a 20-year-old woman with a 12-year history of idiopathic NS revealed by extensive cerebral venous thrombosis with pulmonary embolism treated with anticoagulation therapy and oral corticosteroid therapy followed by mycophenolate mofetil (MMF). The thrombophilia assessment did not show any abnormalities. The evolution was marked by the occurrence of several NS relapses controlled by oral corticosteroid therapy until 2017. Subsequently, the patient had not presented a relapse of her disease. The anticoagulant treatment and the MMF were therefore stopped. One year later, the patient presented with severe diffuse acute abdominal pain associated with postprandial vomiting and bilateral lower limb edema. Laboratory results confirmed a NS relapse. An abdominal CT scan revealed acute thrombosis of the superior mesenteric artery with acute mesenteric ischemia. Intraoperative exploration showed mesenteric ischemia with extensive necrosis of the small intestine making their resections incompatible with life. The patient died after 48 hours. Conclusion: Mesenteric arterial thrombosis, which is a rare but life-threatening NS complication, should always be considered, especially in the case of acute non-specific digestive symptoms.

Pseudoachalasia as the first manifestation of signet-ring cell duodenal carcinoma.

INTRODUCTION: Pseudoachalasia is a rare clinical condition, often caused by malignancy. Rarely, this entity can reveal the underlying neoplasia. To the best of our knowledge, we report the first case of pseudoachalasia revealing a metastatic signet-ring cell carcinoma of the non-ampullary duodenum. CASE REPORT: A previously healthy 67-year-old patient presented with a 3-month history of rapidly progressive intermittent dysphagia with 20kg weight loss. An upper endoscopy showed multiple duodenal ulcerations on congestive mucosa. Duodenal biopsies revealed tumor proliferation formed by independent cells with atypical nuclei. In immunohistochemistry, tumor cells expressed pan-cytokeratin. Esophageal manometry revealed an aspect in favor of achalasia type II. The CT scan showed ascites and pleural effusion. Their punctures confirmed the presence of neoplastic cells. The diagnosis of metastatic signet-ring cell duodenal carcinoma revealed by pseudoachalasia was retained. CONCLUSION: In the presence of rapidly progressive symptoms with significant weight loss, especially in the elderly patients, malignancyassociated pseudoachalasia should be suspected.

Pathologic complete response to neoadjuvant imatinib of a gastric stromal tumor with concomitant mutations in KIT: A case report and literature review.

Key clinical message: We report the first case of pathologic complete response (pCR) to neoadjuvant imatinib in a gastric stromal tumor harboring KIT mutations in both exons 11 and 9. The significance of this co-occurrence is unknown and might increase the responsiveness of gastrointestinal stromal tumors (GISTs) to imatinib. Abstract: pCR of GIST to neoadjuvant imatinib is rare. We report a case of pCR to neoadjuvant imatinib in a gastric stromal tumor that harbored co-occurrence of multiple KIT mutations in exons 11 and 9. This co-occurrence in exons 9 and 11 is the first to be reported in the English literature.

Imputability of Azathioprine in the Occurrence of Chronic Myeloid Leukemia in Crohn's Disease: An Exceptional Case Report.

BACKGROUND: Patients with Cohn's disease (CD) treated with thiopurines are at an increased risk of developing cancer. Leukemias are less frequent than other hematopoietic tumors and the development of Chronic myeloid leukemia (CML) after immunosuppression has not been proven. CASE REPORT: We describe the case of a 61-year-old female who developed a CML after 8 years of treatment with azathioprine (AZA) for ileal Crohn's disease associated with a duodenal localization. We reviewed the current evidence on the interactions between CD, CML and AZA as well as the potential underlying mechanisms of leukemia in AZA-treated patients. CONCLUSION: We concluded that the pathogenesis of CML is multifactorial in CD. The nature of the association between AZA and CML in CD patients warrants further investigation.

Prevalence and risk factors for vitamin D deficiency in Crohn disease patients: A Tunisian study.

INTRODUCTION: Vitamin D plays a role in regulating the immune response through an immunomodulatory effect, and is probably involved in the pathophysiology of Crohn's disease (CD). AIM: to assess vitamin D status in patients with CD as well as in healthy controls and to determine associated factors of vitamin D deficiency in patients with CD. METHODS: We conducted a prospective study over 18 months, including CD patients with age and sex matched with healthy controls. Suboptimal vitamin D status was defined by vitamin D serum level < 30 ng/ml, vitamin insufficiency by vitamin D serum level between 10 and 30 ng/ml and vitamin deficiency serum level < 10 ng/ml. RESULTS: We included 77 subjects (52 patients with CD and 25 controls) with mean age of 38 years± 11. Most patients and controls had suboptimal levels of vitamin D (98% and 96% respectively) including vitamin D deficiency in 75% and 67%, respectively and vitamin D insufficiency in 25% and 33%, respectively. In univariate analysis, vitamin D deficiency was associated with disease flare-up (p=0.001), anemia (p=0.002), hypo-albuminemia (p=0.002), elevated C-reactive protein (CRP) (p=0.003), Crohn's Disease Activity Index (CDAI) (p<0.001), ileal location (p=0.04) and immunosuppressive therapy (p=0.01). In multivariate analysis, only CDAI was significantly associated with vitamin D deficiency (p=0.003, OR=9.33). CONCLUSION: Vitamin D deficiency is common in Tunisian CD patients as well as in controls and is associated with disease activity.

Prevalence and prognosis of Computed-Tomography defined sarcopenia in Tunisian cirrhotic patients.

INTRODUCTION: Sarcopenia is an underdiagnosed and understudied complication of cirrhosis, especially in patients not undergoing liver transplantation. AIM: To evaluate the prevalence and prognostic impact of radiological sarcopenia in non-transplanted cirrhotic patients. METHODS: Longitudinal retrospective study including cirrhotic patients explored by an abdominal CT scan, over a period of 6 years, in a single gastroenterology department in Tunisia. Sarcopenia was defined according to transversal psoas muscle thickness normalized to height (TPMT/h) in the sagittal CT slice. Two groups were defined: Group 1 with sarcopenia (TPMT/h <16.8mm/m); and Group 2 without sarcopenia (TPMT/h ≥16.8mm/m). RESULTS: Seventy patients were included (mean age=62 years). The mean MELD score was 12.81 and the mean TPMT/h of 13.56 mm/m. Forty-four patients were sarcopenic (63%). When included, the 2 groups' baseline characteristics were comparable except for women predominance and refractory ascites in group 1. After an average of 21-month follow-up, sarcopenia was associated with a higher number of complications per patient (p=0.013) and a longer average hospital stay duration per patient (p=0.001). Overall survival was significantly decreased in sarcopenic patients (p=0.035). Survival rates at 6 months, 1 year, and 2 years were respectively 42%, 30%, and 24% in Group 1 versus 67%, 40%, and 27% in Group 2. Sarcopenia was an independent factor of mortality in multivariate analysis (OR=2.5; 95% IC [1.02-6.16]; p=0.045). CONCLUSION: Sarcopenia is frequent and an independent poor prognostic factor in cirrhosis. TPMT/h is an easy and often available method for sarcopenia diagnosis.

Unexpected isolated hepatic tuberculosis discovered during laparoscopic cholecystectomy: A case report.

Isolated hepatic tuberculosis is a rare form of extrapulmonary tuberculosis. We report an exceptional case of a 51-year-old female patient complaining from right upper abdominal quadrant pain, who underwent laparoscopic surgery for millimetric gallbladder polyps. Preoperative ultrasound hepatic morphology and biochemical hepatic tests revealed no abnormalities. There were no clinical patterns for an active tuberculosis. During surgery time, scattered sub-centimeter whitish nodular lesions were discovered on the upper surface of the liver. Although gallbladder pathological examination did not reveal any significant abnormalities, per surgery hepatic biopsy indicated the presence of a giant cell granuloma with caseous necrosis highly suggestive of hepatic tuberculosis. Treatment by anti-bacillary drugs according to local standard protocol was conducted with favorable outcomes. Therefore, diagnosis of hepatic tuberculosis may be considered in endemic countries in totally asymptomatic patients or complaining from unexplained and isolated abdominal pain, in absence of any morphologic or biochemical hepatic abnormalities.

Omphalolith: An underdiagnosed entity.

Omphalolith is a rare and underdiagnosed entity due to the accumulation of sebum and keratin in the umbilicus. It usually occurs in the elderly with deep and narrow umbilicus. Early recognition of omphalolith is important to prevent complications, unnecessary investigations, and anxiety. We report herein two new cases of omphalolith.

Primary hepatic large B-cell lymphoma following direct-acting antiviral treatment for hepatitis C.

Hepatitis C virus (HCV) infection is a major public health concern worldwide, raising important medical and economic issues. HCV-related end-stage liver disease is one of the most common indications for hepatic transplantation. Chronic hepatitis C is also assimilated to a systemic disease because of multiple extrahepatic manifestations, including lymphoproliferative disorders. The revolution of HCV treatment with the advent of direct-acting antivirals has significantly improved the management with high antiviral efficacy and good safety profile compared with old regimens, thus allowing good outcomes on hepatic and extrahepatic symptoms. However, with the widespread use of these new agents, controversial concerns about unexpected increasing cases of hepatocellular carcinoma were reported. We now report the case of a patient presenting with HCV-related cirrhosis, treated with direct-antiviral therapy and diagnosed with primary hepatic lymphoma shortly after the end of the treatment.

An Acute Jejunojejunal Intussusception Revealing a Metastatic Combined Lung Cancer.

Intussusception is a relatively common disease in pediatric age but it is uncommon in adults. We report a case of a 49-year-old male who presented with an acute jejunojejunal intussusception revealed by abdominal pain and vomiting. He underwent an en bloc resection, and pathological findings concluded to a metastasis of a pulmonary combined small cell carcinoma and adenocarcinoma. A subsequent CT scan revealed the primitive mass of the right lung with no evidence of secondary localization. The biopsy was difficult to perform. The patient underwent a pneumonectomy with lymph node dissection confirming the same diagnosis. He made a good recovery from the surgery, and a postoperative chemotherapy was administrated, and he is in remission until this date.

Anemia-induced liver injury: A rare case revealing glucose-6-phosphate dehydrogenase deficiency.

Hypoxic hepatitis may occur due to hemodynamic mechanisms of hypoxia secondary to anemia without any context of reduced blood flow, respiratory failure, or shock state. Etiology of anemia should be investigated in order to avoid recurrence.

Pseudo-Meigs' Syndrome in Tunisian H Syndrome Female Patient: First Case Reported.

H syndrome is an extremely rare autosomal recessive affection caused by biallelic mutations in the SLC29A3 gene encoding the human equilibrative nucleoside transporter hENT3. The hallmark signs are cutaneous consisting of hyperpigmentation and hypertrichosis patches. Besides, associated systemic manifestations are highly various reflecting phenotypic pleiotropism. Herein, we report a first case of pseudo-Meigs' syndrome occurring in a young Tunisian H syndrome diagnosed patient with a novel homozygous frameshift mutation in exon 2 of the SLC29A3 gene: p.S15Pfs*86 inducing a premature stop codon. The patient developed ascites associated with left ovarian mass and she underwent surgery. After tumor resection, ascites disappeared rapidly. Histological examination showed serous cystadenoma of the ovary orienting the diagnosis towards pseudo-Meigs' syndrome.

Evaluation of two nutritional scores' association with systemic treatment toxicity and survival in metastatic colorectal cancer: an AGEO prospective multicentre study.

INTRODUCTION: The Patient-Generated Subjective Global Assessment (PG-SGA) is currently the standard nutritional assessment tool for patients with cancer. In a retrospective assessment of a prospective cohort, we showed that the Nutritional Risk Index (NRI) seemed to be associated with treatment toxicity and survival in patients with metastatic colorectal cancer (mCRC). OBJECTIVE: The objective of this study was to compare these two nutritional tools (PG-SGA and NRI) on their correlation with chemotherapy-related toxicity and survival in non-pre-treated patients with mCRC. METHODS: This prospective multicentre observational study enrolled non-pre-treated patients with mCRC. PG-SGA and NRI were performed at the onset of first-line chemotherapy. Treatment-related toxicities were registered according to National Cancer Institute Common Toxicity Criteria Adverse Event version 4.0. Progression-free survival (PFS) and overall survival (OS) were calculated from the start of treatment. RESULTS: A total of 168 patients were included from eight French centres. Patients were considered malnourished in 41% of cases according to PG-SGA and 56% of cases according to the NRI. In multivariate analysis, malnutrition according to PG-SGA was significantly associated with chemotherapy-related grade ≥2 clinical toxicities (odds ratio: 3.7; 95% confidence interval [CI]: 1.7-8.4; p = 0.001) and OS (hazard ratio [HR]: 2.6; 95% CI: 1.3-5.3; p = 0.006), but not with PFS (HR: 1.5; 95% CI: 0.8-2.6; p = 0.2). Conversely, malnutrition according to the NRI was not significantly associated with these tolerance and efficacy parameters. CONCLUSION: Although more complex to perform in daily oncology practice, the PG-SGA score appears to be the best nutritional assessment tool because of its strong association with clinically relevant oncological outcomes such as OS and treatment-related toxicities in patients with mCRC.

5-FU or mitomycin C hepatic arterial infusion after failure of arterial oxaliplatin in patients with colorectal cancer unresectable liver metastases.

INTRODUCTION: Hepatic arterial infusion (HAI) chemotherapy with oxaliplatin is an accepted option in the management of colorectal cancer (CRC) with dominant liver metastases (LM). However, despite prolonged control, some patients experience disease progression. On the other hand, oxaliplatin leads to dose-limiting toxicity. In these cases, the use of a second-line HAI with an alternative drug has never been reported to date. We evaluated treatment outcomes in patients receiving second-line HAI with 5-FU or mitomycin C, after first-line HAI of oxaliplatin in heavily pretreated patients. MATERIAL AND METHODS: Between March 2010 and June 2016, this observational study included 24 patients with unresectable CRC LM and treated with HAI of 5-FU (17 patients) or mitomycin C (7 patients), after HAI of oxaliplatin. RESULTS: Mean age was 61.7 years. Forty-two percent of patients (10/24) had extra-hepatic metastases and 75% (18/24) at least 8 liver metastases. Including HAI of oxaliplatin, all patients had previously received at least 2 lines of chemotherapy±targeted agents (100%) and 96% (23/24) received concomitant systemic therapies together with HAI of 5-FU or mitomycin C. The overall objective response rate and disease control rate were, respectively, 42% (10/24) and 71% (17/24). Median progression-free survival and overall survival (OS) were, respectively, 5.6 and 25.8 months; hepatic progression-free survival was 8.5months. Thirteen percent (3/24) of the patients received further curative intent treatment after HAI 5-FU and mitomycin C. No toxic death occurred and the toxicity profile was acceptable. CONCLUSIONS: HAI of 5-FU or mitomycin C is an alternative option in patients with predominant CRC LM, when they experience disease progression or do not tolerate HAI of oxaliplatin.

Predictive scores of early mortality from variceal gastrointestinal bleeding in cirrhotic patients.

INTRODUCTION: The variceal bleeding, main complication of portal hypertension during cirrhosis, is associated with high early mortality riskestimated between 15 and 20%. This highlights the necessity of predictive models that allow identifying high-risk patients raising the issue of amore aggressive therapeutic care. OBJECTIVE: To assess the performance of four scores for the prediction of cirrhotic patients' high early mortality risk due to digestive hemorrhageand to compare them to the Child-Pugh reference score. METHODS: We collected 87 cirrhotic patients admitted to the Gastroenterology Department of Charles Nicolle Hospital for a high digestivehemorrhage by rupture of gastric or esophageal varicose veins. RESULTS: 56 men and 31 women were included in this study. The average value of Rockall, Glasgow Blatchford, MELD and MELD-Na scores,was respectively equal to 6.19, 10.91, and 17.6 and at 20. Early mortality was 30%. The average value of all the scores was significantly higherwith the prematurely deceased patients (p<0.001). The MELD-Na score had higher sensitivity and specificity for the prediction of prematuremortality compared to the other scores but without statistical significantly difference (Area under the ROC curve: MELD-Na=0.867, p<0.001;Child-Pugh=0.809, p<0.001; Rockall=0.777, p=0.001; Glasgow-Blatchford=0.761, p<0.001; MELD=0.838, p<0.001). The predictive value of thecut-off MELD-Na score was equal to 19 with a sensitivity of 70% and a specificity of 82%. CONCLUSION: The studied four scores had a good predictive value of early mortality risk by varicose digestive hemorrhage with cirrhotic patients.
