Pancreatic Metastasis of High-Grade Papillary Serous Ovarian Carcinoma Mimicking Primary Pancreas Cancer: A Case Report

Introduction. Reports of epithelial ovarian carcinomas metastatic to the pancreas are very rare. We herein present a metastasis of high grade papillary serous ovarian cancer to mid portion of pancreas. Case. A 42-year-old patient was admitted with a non-specified malignant cystic lesion in midportion of pancreas. She had a history of surgical treatment for papillary serous ovarian adenocarcinoma. A cystic lesion was revealed by an abdominal computerized tomography (CT) performed in her follow up . It was considered as primary mid portion of pancreatic cancer and a distal pancreatectomy was performed. The final pathology showed high-grade papillary serous adenocarcinoma morphologically similar to the previously diagnosed ovarian cancer. Discussion. Metastatic pancreatic cancers should be considered in patients who present with a solitary pancreatic mass and had a previous non-pancreatic malignancy. Differential diagnosis of primary pancreatic neoplasm from metastatic malignancy may be very difficult. A biopsy for tissue confirmation is required to differentiate primary and secondary pancreatic tumors. Although, the value of surgical resection is poorly documented, resection may be considered in selected patients. Conclusion. Pancreatic metastasis of ovarian papillary serous adenocarcinoma has to be kept in mind when a patient with pancreatic mass has a history of ovarian malignancy

Jejunal torsion around the right ureter presenting as postoperative bowel obstruction: a case report

INTRODUCTION: Since abdominal radical hysterectomy was first described by Clark and Reis in 1895, it has been commonly used in the primary surgical treatment of carcinoma of the cervix. We report the case of a 45-year-old woman who was diagnosed with a small bowel obstruction due to jejunal torsion to her right ureter mimicking postoperative adhesion ileus. CASE PRESENTATION: A 45-year-old Turkish woman was admitted to our emergency department with complaints of abdominal pain, constipation, nausea and vomiting. She had undergone an abdominal radical hysterectomy for cervical carcinoma three years earlier. Computed tomography scans revealed intestinal dilatation, a large amount of free fluid in the abdominal cavity and an area suspicious for jejunal perforation. Because of these radiological findings suggestive of obstruction and bowel ischemia, our patient underwent emergency surgery. Operative findings that showed a jejunal segment was turned around her right ureter so that it was mimicking a fibrous band. CONCLUSIONS: In this current case, we present the first determined complication of radical hysterectomy. According to our case report, surgical oncologists should be aware of this complication and review the surgical technique. It is considered that readaptation of the dorsolateral peritoneal layer after extended pelvic lymph node dissection resulted in fewer complications

Cutaneous Necrosis as a Result of Isosulphane Blue Injection in Mammarian Sentinel Lymph Node Mapping: Report of Two Cases

Skin-sparing mastectomy with sentinel lymph node biopsy (SLNB) and synchronous breast reconstruction are widely used in breast cancer surgery nowadays. Difficulties in feeling confident in this technique and postoperative surgical complications are the major obstacles against the widespread usage of this technique. Compared with the other surgical techniques, the complications are hard to treat. Cutaneous necrosis because of methylene blue used for sentinel lymph node mapping in patients who underwent skin-sparing mastectomy and SLNB is already reported in the literature. We present here two cases with cutaneous necrosis because of isosulphane blue injection after skin-sparing mastectomy and SLNB as a rare complication of dye injection

Laparoscopic Treatment of Gallstone Ileus

Gallstone ileus is a rare complication of cholelithiasis that has high morbidity and mortality. An intestinal obstruction can be caused by migration of a large gallstone through a biliary enteric fistula or by impaction within the intestinal tract. In this study, we present the case of an 81-year-old woman with a mechanical bowel obstruction by a gallstone that was treated by laparoscopy
