Serous Microcystic Cystadenocarcinoma of the Pancreas with Synchronous Liver Metastases: Clinical Characteristics and Management.

Serous cystadenocarcinoma of the pancreas is a rare but well-established entity. The origin and evolution of this disorder remain unclear, but even metastatic cases have an excellent prognosis. These tumors are very similar to benign serous cystic neoplasms (SCNs) of the pancreas, except that they tend to be larger, are locally invasive, and present distant metastasis.

Pseudomyxoma Peritonei: Presentation of Two Cases and Challenging Issues in the Literature.

Pseudomyxoma peritonei (PMP) is a rather uncommon syndrome in oncology with a unique biological behavior and an estimated incidence of one to two cases per million per year. Clinically, it usually presents with a variety of unspecific signs and symptoms including abdominal pain and distention, ascites, or even bowel obstruction. Despite its intimidating clinical manifestation, PMP is characterized by satisfactory survival rates when treated with cytoreduction and hyperthermic intraperitoneal chemotherapy (HIPEC).

Low-grade Appendiceal Mucinous Neoplasm Presenting as Adnexal Mass: A Case Report.

An appendiceal mucocele is a dilatation of the appendix and it is the result of benign or malignant diseases, which cause the obstruction of the appendix and the consequent accumulation of mucus secretion. The preoperative diagnosis is difficult due to non-specific clinical manifestations of the disease. We present a case of an 83-year-old female patient with a history of breast cancer that was referred to our hospital for an evaluation of a right adnexal mass discovered during her yearly follow-up.

Inflammatory Pseudotumor of the Liver Presented in a Patient with Cholelithiasis.

An inflammatory pseudotumor of the liver is a rare tumor-like lesion consisting of an inflammatory infiltrate that often can mimic a malignant liver neoplasm. The cause of an inflammatory pseudotumor of the liver is unknown, but it has been reported to be associated with different comorbid conditions most likely inflammatory or infectious in origin. We present an 83-year-old female who presented with a symptomatic gallstones disease and an incidental finding of inflammatory pseudotumor mimicking intrahepatic cholangiocarcinoma in preoperative liver imaging.

Biliary Mucinous Cystic Neoplasm of the Liver with Ovarian Stroma and Elevated Serum and Cystic Fluid Cancer Antigen 19-9 Levels.

Biliary mucinous cystic neoplasms of the liver are rare cystic tumors comprising less than 5% of the liver cystic neoplasms. These tumors demonstrate a female predominance and entail a risk of malignant transformation. We present a 56-year-old female patient with a multiloculated liver cystic lesion measuring 22 cm who underwent a cystectomy with en bloc resection of the liver segments II, III, and cholecystectomy.

Granuloma Mimicking Local Recurrence on PET/CT after Liver Resection of Colorectal Liver Metastasis: A Case Report.

Positron emission tomography-computed tomography (PET/CT) improves the diagnostic interpretation of fluorine-18 fluorodeoxyglucose (18F-FDG ) PET and CT in oncologic patients and has an impact on both diagnostic and therapeutic aspects of patient management. However, false positive findings from the PET/CT imaging should be taken into consideration as they mislead physicians into improper therapeutic actions. We present a 48-year-old female patient with a history of left colectomy for colorectal cancer and subsequent liver metastasectomy.

Clinical Spectrum and Management of Caustic Ingestion: A Case Series Presenting Three Opposing Outcomes.

Background: Ingestion of caustic substances is a medical emergency in both the adult and pediatric population and is associated with high morbidity and mortality. The extent of injuries after ingestion of caustic substances depends on the nature, amount, and concentration of the agent and on the exposure time. Acutely, caustic substances may cause massive hemorrhage and gastrointestinal tract perforation; the most markedly affected cases require urgent surgical treatment.

Eosinophilic Cholangitis--A Challenging Diagnosis of Benign Biliary Stricture: A Case Report.

When confronting a biliary stricture, both benign and malignant etiologies must be carefully considered as a variety of benign biliary strictures can masquerade as hilar cholangiocarcinoma (CCA). Therefore, patients could undergo a major surgery despite the possibility of a benign biliary disease. Approximately 15% to 24% of patients undergoing surgical resection for suspected biliary malignancy will have benign pathology.
