Metastatic Common Bile Duct Cancer from Pulmonary Adenocarcinoma Presenting as Obstructive Jaundice / 대한소화기학회지

We report an extremely rare case of metastatic common bile duct cancer from pulmonary adenocarcinoma presenting as obstructive jaundice. The patient was a 76-year-old male, who presented with generalized weakness and right upper quadrant pain. Plain chest X-ray noted multiple small nodules in both lung fields. Abdominal computed tomography scan showed a stricture of the mid common bile duct along with ductal wall enhancement. Endoscopic retrograde cholangiography revealed a concentric, abrupt narrowing of the mid-common bile duct suggestive of primary bile duct cancer. However, pathology comfirmed metastatic common bile duct cancer arising from pulmonary adenocarcinoma with immunohistochemical study with thyroid transcriptional factor-1 (TTF-1).

Ampuloma: ¿terapia endoscópica o quirúrgica? / Ampullary neoplasms: endoscopic or surgical treatment?

Ampullary neoplasms may correspond to adenoma or adenocarcinoma. The study of its staging is performed by means of computed tomography, magnetic resonance imaging and endosonography. The appropriate classification of the stages allows for a better planning of treatment. In benign tumors and small selected carcinoma, ampullectomy (endoscopic or surgical) is an alternative. In patients with ampullary neoplasms invading deep extension or showing high risk of recurrence, without evidence of metastasis, pancreatodudodenectomy is the treatment of choice. In those cases with distant metastasis, palliative treatment is indicated.

Las neoplasias ampulares pueden corresponder a adenomas o adenocarcinomas. El estudio de etapificación se realiza con tomografía computada, resonancia magnética y endosonografía. La correcta clasificación en estadíos, permite planificar de mejor forma el tratamiento. En tumores benignos y seleccionados carcinomas pequeños, la ampulectomía (endoscópica o quirúrgica) es una alternativa. En pacientes con neoplasias ampulares que presentan extensión en profundidad o alto riesgo de recurrencia, sin evidencia de metástasis a distancia, estaría indicada la pancreatoduodenectomía. En aquellos casos con metástasis a distancia, se aplican técnicas paliativas.

Peri-ampullary collision tumor - high grade neuroendocrine carcinoma and signet ring cell carcinoma: A case report and review of literature.

We report a case of 50-year-old male with obstructive jaundice diagnosed as peri-ampullary collision tumor comprising of large cell neuroendocrine carcinoma and signet ring cell carcinoma. The association of neuroendocrine (usually carcinoids) and adenocarcinoma is extremely uncommon with only few case reports available in the reported literature.

A Case of Primary Mucoepidermoid Carcinoma Arising from the Common Bile Duct / 대한소화기학회지

Mucoepidermoid carcinoma of the bile duct is an extremely rare tumor. Seventeen cases originating from intrahepatic bile duct and 2 cases from common hepatic duct have been reported in the English literature. Mucoepidermoid carcinoma arising from the common bile duct has not been previously reported. A 68 year-old man was admitted due to obstructive jaundice. Computed tomography showed a malignant tumor of the common bile duct located in the intrapancreatic segment. Filling defects of the distal common bile duct was seen on endoscopic retrograde cholangiogram. Under the impression of bile duct cancer, pylorus-preserving pancreatoduodenectomy was performed. Histologic diagnosis of the resected specimen was mucoepidermoid carcinoma of the common bile duct. After surgery, the patient received concurrent chemoradiotherapy, and planned to receive additional chemotherapy. We herein report on a first case of primary mucoepidermoid carcinoma of the common bile duct, and review the literature.

Adenocarcinoma de la ampolla de Vater: a propósito de un caso / Vater's ampulla adenocarcinoma: a propos of a case

El 99 por ciento de los tumores malignos de la ampolla de Vater, son carcinomas. Resultan infrecuentes y de difícil diagnóstico, ya que concurren en el área, las patologías pancreáticas, del tercio distal del conducto biliar común, conducto pancreático y mucosa duodenal adyacente. El término carcinoma ampular no sólo hace referencia a una ubicación topográfica, sino también al origen histológico de los mismos, pues implica que deriva de la mucosa intestinal que tapiza dicha región. Se comunica un caso diagnosticado en el Hospital Militar Docente Dr. Mario Muñoz Monroy, de Matanzas, que acudió con un síndrome ictérico, y luego de realizada la colangiografía retrógrada endoscópica (CPRE) con toma de biopsia, ultrasonido y TAC abdominal, se pudo llegar al diagnóstico de adenocarcinoma mucoproductor de la ampolla de Vater. Fue sometido a cirugía radical con resultado exitoso...

99 per cent of the Vater's ampulla malignant tumours are carcinomas. They are infrequent and of difficult diagnosis, because there is a concurrence in the area of pancreatic diseases, of the distal third of the common bile duct, of the pancreatic duct and the adjacent duodenal mucosa diseases. The term ampullar carcinoma refers not only to a topographic location but also to their histological origin; because it implies that it derives from the intestinal mucosa that coats the region. We deal with a case diagnosed at the Teaching Military Hospital Dr. Mario Muñoz Monroy, of Matanzas, assisting the hospital with an icteric syndrome. After making an endoscopic retrograde cholangiography with biopsy, ultrasound and abdominal tomography, we arrived to the diagnosis of a Vater's ampulla mucoproductor adenocarcinoma. The patient received a radical surgery with successful results...

Metachronous Four Primary Malignancies in Gastro-intestinal Tract / 대한소화기학회지

Multiple primary malignancy was reported firstly by Billroth in 1889. Recently, multiple primary malignancies are considered to increase due to improved survival rate of cancer patients, advanced diagnostic tools, and increased use of chemotherapy and radiotherapy. In Korea, several cases of triple primary malignancies were reported. However, four primary malignancies in gastro-intestinal tract was rarely reported. Recently, we experienced a 70 year-old male who was diagnosed with metachronous four primary malignancies in rectum, ascending colon, stomach, and ampulla of Vater. We report this rare case of metachronous four primary malignancies with a review of literature.

Amputation Neuroma Mimicking Common Bile Duct Cancer: A Case Report / 대한소화기학회지

Amputation neuroma or traumatic neuroma is a tumor-like secondary hyperplasia that may develop after an accidental or surgical trauma. Amputation neuroma of the bile duct has occasionally been reported which occurred in the cystic duct stump late after the cholecystectomy. However, even if the amputation neuroma is suspected in a patient with late-onset jaundice after cholecystectomy, the differential diagnosis from a malignancy is difficult preoperatively. We experienced a case of the amputation neuroma of common bile duct (CBD) developed in a 70-year-old man who presented with a polypoid mass in CBD. He had undergone cholecystectomy 25 years ago and choledochojejunostomy 12 years ago, respectively. We have performed pylorus-preserving pancreatico-duodenectomy (PPPD) under the impression of CBD cancer. He had not been diagnosed of amputation neuroma until having undergone PPPD. We report a case of CBD neuroma mimicking CBD cancer, which was confirmed after PPPD.

The Usefulness of Percutaneous Transhepatic Cholangioscopy for Identifying Malignancies in Distal Commom Bile Duct Strictures

The diagnostic accuracy of percutaneous transhepatic cholangioscopy (PTCS) was compared to that of three radiologic modalities in distal common bile duct (CBD) strictures for the evaluation of clinical application. Ninety-five patients who underwent PTCS for the evaluation of distal CBD strictures (35 malignant and 60 benign) whose masses were not obvious from radiologic imagings were included. Confirmative diagnosis could not be reached by endoscopic retrograde cholangiopancreatography (ERCP) or radiologic findings in all cases. Specific findings on the computed tomography (CT), magnetic resonance cholangiopancreatography (MRCP) and direct cholangiography were analyzed among 68 (25 malignant and 43 benign) out of the 95 patients in order to determine the sensitivity and specificity of three radiologic studies for the diagnosis of malignant distal CBD strictures, and to compare those results with those by a combination of PTCS-guided biopsy and tumor vessel observation on cholangioscopy. The sensitivity/specificity of CT, MRCP and direct cholangiography including ERCP in diagnosing malignant distal CBD strictures were 42.9%/65.8%, 53.3%/58.3%, and 70.8%/47.6% respectively, while it was 96%/100% for the combination of PTCS-guided biopsy and tumor vessel. PTCS is a useful method for differential diagnosis of distal CBD strictures, particularly when it is difficult to distinguish benign from malignant strictures by radiologic studies and when peroral approach is not feasible.

Embryonal rhabdomyosarcoma of the biliary tree mimicking a choledochal cyst.

Embryonal rhabdomyosarcoma (ERMS) of biliary tree is a rare type of mesenchymal neoplasm diagnosed at surgery or by preoperative liver biopsy. We present a one year eight months old child who mimicked a choledochal cyst and was eventually treated with surgery, chemotherapy with IRS IV protocol and adjuvant postoperative radiotherapy to surgical bed with 6 MV photons to a dose of 5040 cGy in 28 fractions.

A Case of Hepatectomy for Liver Metastasis after Pancreatoduodenectomy for Carcinoma of Ampulla of Vater / 대한소화기학회지

After curative resection of carcinoma of ampulla of Vater, 5-year survival rate has been reported ranging from 40% to 60%. Two major causes of the treatment failure are local recurrence and liver metastasis. Liver metastases are often multiple and are associated with poor prognosis. There have been few reports on long-term survivors after hepatectomy for metastatic liver tumors from carcinoma of ampulla of Vater. We report a 42 year-old female patient with solitary hepatic metastasis from carcinoma of ampulla of Vater, which was successfully treated by hepatectomy 69 months after curative Whipple's operation. Histologic examination of the resected specimen had revealed stage IB moderately-differentiated, intestinal type adenocarcinoma (T2N0M0). Since neither local recurrence or distant metastasis were detected, the patient underwent liver segmentectomy. Histologic study confirmed the presence of metastatic liver tumor from carcinoma of ampulla of Vater. She is doing well without evidence of recurrence at 20 months after hepatectomy.

A Case of Leiomyoma in the Common Bile Duct / 대한소화기학회지

Leiomyomas, originating in the bile duct, are very rare, and only few cases have been reported in the literature. We experienced a case of leiomyoma of the distal common bile duct, mimicking bile duct cancer. A 39-year-old woman presented with intermittent jaundice and general weakness for three months. Clinical profiles showed obstructive jaundice, and the abdominal computed tomography and cholangiography revealed diffuse bile duct dilatation with distal common bile duct stricture. A pylorus-preserving pancreaticoduodenectomy was performed and the pathologic specimen disclosed leiomyoma of the common bile duct accompanying severe fibrosis. This is the first case of leiomyoma in the bile duct reported in Korea.

A Case of Carcinoid Tumor of the Common Bile Duct / 대한소화기학회지

Majority of malignant neoplasms arising from the extrahepatic bile duct are adenocarcinomas. Carcinoid tumors at this site are extremely rare. We report a 67-year-old woman with malignant carcinoid tumor of the common bile duct. She presented with obstructive jaundice of 1 week's duration. Abdominal CT and ERCP revealed a common bile duct mass. She underwent Whipple's operation and was diagnosed as malignant carcinoid tumor histologically and immunohistochemically.

Tumores periampulares: hallazgos y resultados en 21 casos consecutivos resecados / Periampullary tumors: finding and result of 21 consecutive operated cases

Los cánceres de la región periampular (CPA) han experimentado un incremento significativo en las últimas décadas, actualmente comprenden cerca del 2 por ciento de las neoplasias malignas, con una incidencia aproximada en 10 por 100.000 habitantes en USA. El objetivo de este estudio es describir y analizar los resultados obtenidos en el manejo de pacientes resecados con diagnóstico de tumor periampular (TPA) que fueron intervenidos en el Hospital Clínico Regional de Valdivia entre los años 2000 y primer trimestre de 2005. Se realizó un estudio retrospectivo en el que se revisaron fichas clínicas de pacientes en los que se diagnóstico un TPA y se incluyeron en protocolo preestablecido. Se creó una base de datos Excel y el análisis estadístico se realizó con programa Epi-Info 2002. Durante el período en estudio se intervinieron 21 casos con diagnóstico de TPA. La presentación clínica más común fue el debut como ictericia obstructiva asociado a dolor abdominal. El estudio preoperatorio se efectuó con laboratorio básico, ECO y/o TAC de abdomen. En 10 casos se realizó CPER previo a la cirugía. La pancreatogastroanastomosis se utilizó en el 95 por ciento de los casos. El aporte nutricional postoperatorio se realizó mayoritariamente por vía enteral. La morbilidad general alcanzó un 48 por ciento. Las complicaciones más frecuentes fueron las intraabdominales; dentro de éstas hubo 2 casos de fístulas pancreáticas. No se presentó mortalidad operatoria. El cáncer de ampolla fue el más frecuente en esta serie y el compromiso metastático linfonodal se presentó en un 52 por ciento. Se concluye que los CPA se presentan habitualmente con ictericia y dolor abdominal. El cáncer de ampolla es el tumor más frecuentemente resecado y la morbimortalidad de la cirugía es similar a lo reportado por experiencias de centros de alto volumen en pancreatoduodenectomía.

Ectopic pancreatic tissue mimicking ampullary tumor.

Ectopic pancreas is an anomaly in the fusion of the two pancreatic buds where an ectopic rest develops at a place away from the normal site. We report a 70-year-old lady who presented with obstructive jaundice; she was found to have an ampullary tumor highly suggestive of malignancy, for which she underwent pancreatico-duodenectomy. However, histology showed ectopic pancreatic tissue in the ampulla.

Granular cell tumour of the ampulla of Vater.

Granular cell tumour (GCT) is a rare soft tissue neoplasm commonly encountered in the head and neck region, skin and subcutaneous tissue. GCT of the biliary system is most commonly reported in African-American females and usually presents as abdominal pain and obstructive jaundice. The neoplasm constitutes less than 10% of all benign tumours of the extra-hepatic biliary tree. No case of GCT involving the ampulla of Vater has been reported in the literature to date. We report a case of benign GCT involving the ampullary region in a 44-year-old Ethiopian male. Preoperative diagnosis was available on ERCP and deep biopsy. The patient was managed by debulking resection and biliary-enteric bypass and is symptom-free with no evidence of tumour progression after a follow-up of one year.

Treatment Outcome after Endoscopic Papillectomy of Tumors of the Major Duodenal Papilla / 대한소화기학회지

BACKGROUND/AIMS: Endoscopic papillectomy is reported to be relatively safe and reliable for complete resection of benign tumors of the major duodenal papilla. We evaluated methods and treatment outcome of the patients who have undergone endoscopic papillectomy. METHODS: Medical records of 22 consecutive patients with tumor of the major duodenal papilla (10 women, 12 men; mean age 55.8+/-2.8 yrs) who have undergone endoscopic papillectomy were reviewed retrospectively. Endoscopic papillectomy was defined the successful when complete excision of the tumor was achieved. RESULTS: Mean duration of follow-up was 8.4+/-2.4 months (range 1-43 months). Endoscopic papillectomy was successful in 16 patients (72.7%), but incomplete resection occurred in 6 patients. Only one patient showed recurrence. Histopathologic evaluation after endoscopic papillectomy revealed adenoma (n=11, 50%), high-grade dysplasia (n=3, 13.6%), adenocarcinoma (n=2, 9.1%), carcinoid (n=1), chronic inflammation (n=3, 13.6%), papillary adenomatous hyperplasia (n=1), and cavernous lymphangioma (n=1). The mean size of the resected lesions was 10.3+/-1.2 mm (range 2-20 mm). There was no factor which could predict the endoscopic success statistically. A pancreatic duct stent was placed in 11 patients (50.0%) and was removed after 3 to 39 days. There were 8 (36.8%) procedure-related complications: bleeding (n=4), papillary stenosis (n=1), perforation (n=1), cholangitis (n=1), and asymptomatic liver function abnormality (n=1). There was no pancreatitis or mortality. All the complications resolved with conservative management. CONCLUSIONS: Endoscopic papillectomy in selected patients seemed to be highly successful and safe. Longer follow-up is needed to assess the long-term efficacy.

Malignant Gastrointestinal Stromal Tumor of the Ampulla of Vater: A Case Report / 대한소화기학회지

GIST is a rare neoplasm, the majority of GISTs are located in the stomach and small intestine. Most GISTs are diagnosed histopathologically after resection because of submucosal location. A 37-year-old female patient presented with a 2-weeks history of generalized weakness, nausea accompanied by intermittent passage of black, tarry stools. Esophagogastroduodenoscopy and ERCP showed a large round mass measuring 5 cm in diameter in the ampulla of Vater with ulcer crack. Endoscopic multiple biopsies from the mass including ulcer base were taken. Light microscopic findings showed spindle-shaped and epitheloid tumor cells having high cellularity and frequent mitotic figures. On immunohistochemical stainings, the tumor cells were positive for CD34 and smooth muscle actin. Based on these preoperative findings, a diagnosis of malignant GIST of the ampulla of Vater was made probably. After operation, immunohistochemical studies revealed positive reaction for c-kit and vimentin, as well as focally reactive for CD34 and smooth muscle actin. We report a case of GIST in the ampulla of Vater presenting with melena that was diagnosed preoperatively and postoperatively.

A Case of Primary Small Cell Carcinoma in the Common Bile Duct / 대한소화기학회지

Extrapulmonary primary small cell carcinoma comprises approximately 4% of all small cell carcinoma. In the common bile duct, small cell carcinomas are extremely rare. We experienced a 60-year-old woman with small cell carcinoma arising in the common bile duct. Abdominal CT scan revealed an intraluminal mass in the proximal common bile duct and multiple lymphadenopathies. Microscopic examination of the tumor revealed proliferation of small monotonous anaplastic cells, which were characterized with hyperchromatic nuclei, high nuclear to cytoplasmic ratio, and frequent mitosis. By immunohistochemical stain, the tumor cells were strongly positive for chromogranin, synaptophysin, and CD56. We report this case with a review of literatures.
