Metastatic pancreas tumors from breast cancer are comparatively uncommon and patients with this tumor usually remain asymptomatic during their life. A 55-year-old woman presented with obstructive jaundice following mastectomy for invasive ductal carcinoma. We diagnosed obstructive jaundice due to a pancreatic tumor demonstrated on computed tomography and performed percutaneous transhepatic cholangio-drainage. Although the patient recovered from the jaundice, she had exacerbation of pneumonia from which she died. At autopsy, invasive ductal carcinoma was found in the pancreas tumor. Immunohistochemical staining was performed to confirm whether the pancreatic tumor was primary or secondary. Human milk fat globules 1 and 2 and gross cystic disease fluid protein-15, which characteristically exist in normal breast tissue or breast carcinoma, were expressed both in the primary breast tumor and the pancreatic tumor. In contrast, both the anti-estrogen receptor and anti-progesterone receptor antibodies stained positively in the primary breast cancer; however, neither of them was positive in the metastatic pancreatic tumor. We report a rare case of a patient who presented with obstructive jaundice from a pancreatic tumor metastasizing from breast cancer and in whom immunohistochemical staining using the antibodies unique to the mammary gland was effective for the diagnosis of this secondary tumor.

Background. Biliobronchial fistula (BBF) is a rare complication in the natural history of liver hydatid disease by Echinococcus granulosus. We present a case of BBF after resection of a giant liver hydatid cyst in a 72-year-old woman. Case Report. A total cystpericystectomy was done, leaving the left lateral section of the liver that was fixed to the diaphragm. Postoperatively, the patient developed obstructive jaundice. An ERCP showed an obstruction at the junction of the left biliary duct and the main biliary duct and contrast leak. At reoperation, the main duct was ischemic, likely due to torsion along its longitudinal axis. A hepatotomy was done at the hilar plate, and the biliary duct was dissected and anastomosed to a Roux-en-Y jejunal loop. She was discharged without complications. Five months later, the patient developed cholangitis and was successfully treated with antibiotics. However, she suffered repeated respiratory infections, and four months later she was admitted to the hospital with fever, cough, bilioptysis, and right lower lobe pneumonia. The diagnosis of BBF was confirmed with (99m)Tc Mebrofenin scintigraphy. At transhepatic cholangiography, bile duct dilation was seen, with a biliothoracic leak. She underwent dilatation of cholangiojejunostomy stricture with placement of an external-internal catheter. The catheter was removed 3.5 months later, and two years later the patient remains in very good condition. Conclusion. An indirect treatment of the BBF by percutaneous transhepatic dilation of the biliary stenosis avoided a more invasive treatment, with satisfactory outcome.

Xanthogranulomatous cholecystitis is a rare variant of chronic cholecystitis characterized by severe proliferative fibrosis and accumulation of lipid-laden macrophages in regions of destructive inflammation. Xanthogranulomatous cholecystitis clinically and radiologically mimics early-stage gallbladder cancer, with wall thickening on computed tomography. The study included 14 xanthogranulomatous cholecystitis patients that were identified following retrospective analysis of the records of 1248 patients that underwent cholecystectomy between 2005 and 2011. Mean age of the 5 male and 9 female patients was 56.7 years. All 14 patients had gallbladder stones; 10 had a history of acute cholecystitis, 1 had cholangitis, and 2 presented with obstructive jaundice. A right-upper quadrant mass was palpable in 2 patients. All patients underwent cholecystectomy. Open surgery was planned and performed in 6 of the 14 patients, and laparoscopic cholecystectomy was planned in 8 patients, but was converted to open surgery in 1 case. In total, 1 patient developed wound infection, 1 patient had postoperative pneumonia, and 1 patient developed intraabdominal hematoma. None of the patients in the series died. Xanthogranulomatous cholecystitis is difficult to diagnose, both preoperatively and intraoperatively, and definitive diagnosis depends exclusively on pathological examination. Xanthogranulomatous cholecystitis should be a consideration in all difficult cholecystectomy cases.

Biliary-pleural fistula (BPF), an abnormal communication between the biliary tract and pleural space, is a rare but potentially life-threatening complication following percutaneous biliary intervention. We report a case of BPF following portal vein embolization (PVE) in a 79-year-old woman with obstructive jaundice secondary to perihilar cholangiocarcinoma. The patient successfully underwent right-sided PVE; however, the patient developed a symptomatic right-sided bilious pleural effusion the following day. Despite aggressive drainage of the pleural effusion with a large-bore chest tube and maximal medical management, the patient died from respiratory failure and pneumonia. Although rare, knowledge of this complication is important when performing PVE in patients with biliary obstruction because it can be life-threatening. Early recognition and management of this complication are crucial to avoid a poor outcome.

Background: Ampullary adenocarcinomas are a rare subset of periampullary tumors with an overall poor prognosis. Treatment decisions are generally extrapolated from pancreatic chemotherapy protocols and consist mainly of traditional chemotherapy drugs. There are no known targets for therapeutic intervention in ampullary adenocarcinoma at this time. Next generation sequencing and other novel molecular profiling of tumors, including circulating tumor DNA (ctDNA), have recently made it possible to better understand tumor biology and elucidate driver mutations which are amenable to targeted therapy. This case describes the use of novel DNA sequencing technology to provide a targeted treatment option, HER-2 inhibition, in a patient with HER-2 overexpressing ampullary adenocarcinoma. This is the first time this has been described in the literature. Case presentation: The patient is a 63-year-old Caucasian man who initially presented with symptoms of obstructive jaundice and was found to have a periampullary tumor. He underwent resection of his tumor and pathology confirmed a stage IIB ampullary adenocarcinoma. He unfortunately developed a recurrence in the liver and lung two years later. Next generation sequencing of his tumor at the time of resection as well as ctDNA analysis demonstrated a HER-2 overexpressing tumor. Following first line therapy with FOLFOX he had progression and was treated with trastuzumab and pertuzumab with stabilization of his disease prior to his ultimate demise from multifocal pneumonia. Conclusion: The use of next generation sequencing as well as ctDNA technology generated a novel therapeutic intervention in our patient. As these techniques become more widespread, it is likely more targeted therapies will be used in these difficult to treat diseases.

BACKGROUND Rupture of a pyogenic liver abscess is rare but serious complication. In patients after pancreatoduodenectomy, there are some conditions causing the development of liver abscesses (e.g., chronic reflux-cholangitis, efferent jejunal loop stasis, stenosis of the biliary anastomosis, and pancreatogenic diabetes). However, the number of published cases of liver abscess after pancreatoduodenectomy is small. CASE REPORT A 42-year-old male was admitted with severe abdominal pain, fever, and jaundice. Nineteen years previously, he had undergone pancreatoduodenectomy and cholecystectomy for chronic pancreatitis with obstructive jaundice. Two years later, diabetes mellitus was diagnosed, with subsequent insulin treatment. At admission, symptoms of peritonitis were present. Plain abdominal radiography showed free gas under the right hemidiaphragm and heterogeneous liver shade with small gas-fluid levels. The rupture of a liver abscess was suspected. Laparotomy with adhesiolysis, debridement of the liver abscess cavity, and abdominal drainage were performed. The postoperative period was complicated by sepsis, right lower lobe pneumonia, and two-sided pleural effusions, on the background of insulin-dependent diabetes and malnutrition. The patient was discharged on the 40th day and the subdiaphragmatic drains were removed on the 114th day. Sixteen months after surgery, the patient's condition was satisfactory. Magnetic resonance imaging and echography showed the absence of biliary hypertension. The liver tissue had healed completely. CONCLUSIONS A unique case of ruptured liver abscess after pancreatoduodenectomy is presented. To the best of our knowledge, this is the first published case with such a long time interval (19 years) between pancreatoduodenectomy and the formation of a pyogenic liver abscess.

Eosinophilic cholecystitis is a rare post-cholecystectomy inflammatory histopathological condition characterized by more than 90% eosinophilic infiltrate in the gallbladder. We present a case of 27-year female presented with abdominal pain, fever, jaundice, altered mental status, shock, leucocytosis, deranged liver function test, and peripheral blood eosinophilia. The patient underwent cholecystectomy and common bile duct exploration. She developed adult respiratory distress syndrome and hospital-acquired pneumonia. From this, we want to emphasize that eosinophilic cholecystitis and cholangiopathy should be a differential diagnosis in patients presenting with allergy, peripheral eosinophilia, obstructive jaundice that are planned to undergo cholecystectomy that will have early critical care intervention.
