Polycystic liver disease: An uncommon genetic condition.

Key Clinical Message: Timely recognition, accurate diagnosis, and proper management are vital for preventing complications and improving outcomes in polycystic liver disease. Abstract: Polycystic liver disease is an uncommon genetic condition characterized by the presence of over 20 liver cysts. It is symptomatic in only 5% of cases. Surgical intervention remains the primary treatment approach for managing symptoms in affected patients. Herein, we report a case of PLD revealed by severe abdominal pain.

A rare pancreatic neoplasm in a 40-year-old male patient.

Key Clinical Message: The differential diagnoses of solid pseudopapillary neoplasm of the pancreas include cystic pancreatic neuroendocrine tumor, acinar cell carcinoma, and pancreatoblastoma. Abstract: Solid pseudopapillary neoplasm (SPN) is a low-grade malignant pancreatic tumor which accounts for 0.9%-2.7% of all exocrine pancreatic neoplasms. It predominantly affects young females (90%) and less frequently occurs in male patients. Its prognosis after surgical resection remains excellent. Herein, we report a case of SPN in a male patient.

Submucosal micropapillary adenocarcinoma of the sigmoid colon: A distinct and aggressive subtype of adenocarcinoma.

Colorectal invasive micropapillary carcinoma (MPC) is a rare and distinct variant of adenocarcinoma with high incidence of lymph node metastasis. The differential diagnoses of MPC include extensive lymphovascular invasion, metastatic MPC, and retraction artifacts.

A new One Health Framework in Qatar for future emerging and re-emerging zoonotic diseases preparedness and response.

One Health is increasingly recognized as an optimal approach to address the global risk of health threats originating at the human, animal, and ecosystem interface, and their impact. Qatar has successfully practiced One Health approach for investigation and surveillance of zoonotic diseases such as MERS-CoV, and other health threats. However, the current gaps at institution and policy level hinder the sustainment of One Health. In this paper, we have assessed the potential for implementation of One Health Framework to reinforce and sustain One Health capacities in Qatar for 2022-2027. To implement One Health Framework in the country, Qatar Joint External Evaluation (JEE) report, lessons learnt during One Health experiences on zoonotic, vector-borne, and food borne diseases were used to present an outline for multisectoral coordination. In addition, technical capacities of One Health and factors that are required to operationalize it in the country were also assessed in series of meetings and workshops held at Ministry of Public Health on March 2022. Present health care infrastructure and resources were found to be conducive for effective management and response to shared health threats as evident during MERS-CoV, despite being more event based. Regardless, the need for more sustainable capacity development was unanimously emphasized. The consensus between all relevant stakeholders and partners was that there is a need for better communication channels, policies and protocols for data sharing, and the need to invest more resources for better sustainability. The proposed framework is expected to strengthen and facilitate multilateral coordination, enhanced laboratory capacity and network, improve active surveillance and response, risk communication, community engagement, maximize applied research, and build One Health technical work force. This would enable advancement and sustainment of One Health activities to prevent and control health threats shared between humans-animals-ecosystem interface.

Goblet cell adenocarcinoma of the ascending colon: An underrecognized diagnostic pitfall.

Goblet cell adenocarcinomas (GCA) are infrequent neoplasms of the digestive system that exhibit both mucinous and neuroendocrine differentiation. They predominate in the appendix and rarely involve the colon. Herein, the authors report a case of GCA involving the ascending colon in a 60-year-old woman who presented with severe anemia.

Tuberculous abdominal cocoon: A rare variant of peritonitis.

Cocoon abdomen is an uncommon condition characterized by bowel entrapment in a cocoon-like membrane. Its clinical presentation is usually non-specific. Rarely, it may present with perforation peritonitis. The therapeutic approach depends on the stage of the disease. Surgery is essentially reserved for those with acute surgical complications.

Adenosquamous carcinoma of the pancreas: A rare and aggressive variant of pancreatic cancer.

Adenosquamous carcinoma of the pancreas is a rare and aggressive histological subtype of pancreatic adenocarcinoma, which accounts for 1% to 4% of the exocrine pancreatic malignancies. Its diagnosis relies on histological examination revealing the coexistence of ductal adenocarcinoma and squamous carcinoma with the latter representing ≥30% of the tumor.

Huge mesenteric desmoid-type fibromatosis with unusual presentation: A case report.

Introduction: Desmoid-type fibromatosis, also known as desmoid tumors, are rare fibroblastic neoplasms that account for less than 3% of all soft tissue tumors. Although they are benign neoplasms without metastatic potential, they are known to be locally aggressive and may invade adjacent structures leading to fatal complications. Case presentation: We describe the case of a 26-year-old woman who presenting with the clinical picture of acute peritonitis. Emergency surgery was performed and a large poorly-circumscribed heterogeneous tumor was found, occupying the jejunum mesentery and infiltrating the jejunal wall causing its perforation into the abdominal cavity. En bloc resection of the tumor and the involved jejunum was performed. Histology and immunohistochemistry confirmed it to be mesenteric desmoid-type fibromatosis. The postoperative course was uneventful and the patient had no evidence of recurrence 18 months after tumor resection. Conclusions: Mesenteric desmoid-type fibromatosis is a rare condition with insidious growth and locally aggressive behavior. Serious complications such as bowel perforation are rare but possible, as shown in our presentation. Complete surgical resection is the first-line treatment bur high recurrence rates remain problematic.

Bifocal intracholecystic tubulopapillary neoplasm: A rare and distinct tumor of the gallbladder.

Intracholecystic papillary-tubular neoplasms are rare precancerous and polypoid lesions of the gallbladder, found in nearly 0.4% of cholecystectomy specimens. They follow the adenoma-carcinoma sequence. About half the cases are associated with invasive carcinoma. Their diagnosis relies on histopathological examination with extensive sampling of the surgical specimen.

Puzzling hepatic tumor: Epithelioid angiomyolipoma.

Hepatic epithelioid angiomyolipomas are uncommon mesenchymal neoplasms. They are difficult to diagnose by imaging, especially when the fatty component is scant or absent. The gold standard for the diagnosis is histologic examination coupled with an immunohistochemical study. Positive HMB45 immunostaining of the myoid cells is a major diagnostic feature.

Peculiar thousand leaves soft-tissue mass: Elastofibroma dorsi.

Elastofibroma dorsi is an uncommon benign soft-tissue tumor with uncertain pathogenesis (Medicina (Kaunas), 2021; 57, 370). Surgical excision is the therapeutic option for symptomatic patients. A pathological study confirms the diagnosis after surgery. The prognosis is excellent with extremely rare recurrence cases (Anticancer Res, 2021, 41, 2211).

Actinomycosis mimicking a pancreatic head neoplasm: A case report.

INTRODUCTION: Actinomycosis is a chronic suppurative disease caused by a filamentous, Gram-positive, facultative anaerobic bacterium Actinomyces. Abdominal actinomycosis accounts for 10 to 20% of reported Actinomyces infections and pancreatic involvement is extremely rare. PRESENTATION OF CASE: We report the case of a 64-year-old man who presented with a 3-week history of abdominal pain, nausea, weight loss, and icterus. Abdominal CT scan revealed a 3.5 cm heterogeneously enhanced mass of the pancreatic head, associated with mild dilation of the main bile duct and the Wirsung duct. The diagnosis of pancreatic head malignancy was highly suspected and surgical management was decided. Intraoperatively, a 3 cm indurated mass of the pancreatic head was found. Whipple's procedure was performed. Histopathological examination revealed pancreatic actinomycosis. DISCUSSION: Pancreatic actinomycosis is extremely rare. To our knowledge, only 18 cases have been reported in the English literature to date. It commonly presents as a slow-growing mass with bile and pancreatic ducts obstruction, which can mimic malignancy. Therefore, it has often been misdiagnosed and over-treated with futile surgery, when medical treatment based on antibiotherapy is the only required treatment. CONCLUSION: We reported a rare observation of surgical management of actinomycosis mimicking a pancreatic head neoplasm. As clinical and radiological findings are nonspecific, the accurate diagnosis can only be made by histology. Through our case, we aim to highlight the importance of preoperative suspicion of pancreatic actinomycosis, given the still relevant morbidity of pancreatic resections.

Ambulatory hernia repair: a study of 1294 patients in a single institution.

Introduction: ambulatory surgery is continuously expanding in global reach because of its several advantages. This study aimed to describe the experience of our department in outpatient hernia surgery, evaluate its feasibility and safety, and determine the predictive factors for failure of this surgery. Methods: we conducted a monocentric retrospective cohort study on patients who had ambulatory groin hernia repair (GHR) and ventral hernia repair (VHR) in the general surgery department of the Habib Thameur Hospital in Tunis between January 1st, 2008 and December 31st, 2016. Clinicodemographic characteristics and outcomes were compared between the successful discharge and discharge failure groups. A p-value of ≤ 0.05 was considered significant. Results: we collected data from the record of 1294 patients. One thousand and twenty patients had groin hernia repair (GHR). The failure rate of ambulatory management of GHR was 3.7%: 31 patients (3.0%) had unplanned admission (UA) and 7 patients (0.7%) had unplanned rehospitalization (UR). The morbidity rate was 2.4% while the mortality rate was 0%. On multivariate analysis, we did not identify any independent predictor of discharge failure in the GHR group. Two hundred and seventy-four patients underwent ventral hernia repair (VHR). The failure rate of ambulatory management of VHR was 5.5%: 11 patients (4.0%) had UA and 4 patients (1.5%) had UR. The morbidity rate was 3.6% and the mortality rate was zero. On multivariate analysis, we did not identify any variable predicting discharge failure. Conclusion: our study data suggest that ambulatory hernia surgery is feasible and safe in well-selected patients. The development of this practice would allow for better management of eligible patients and would offer many economic and organizational advantages to healthcare structures.
