  • Aim: To report the histologic findings on Whipple resection specimens and thus determine the extent and spread of carcinomas of ampullary region and head of pancreas in our population. Setting: Section of Histopathology, Department of Pathology, Aga Khan University Hospital (AKUH), Karachi, Pakistan. Materials and Methods: A case series of 311 consecutive Whipple resection specimens received between January 1,2003 and December 31, 2014. Specimens processed for histologic sections and representative sections submitted and histologically examined as per established and standard protocols. All relevant tumor parameters including histologic type, histologic grade, pathologic T and N stage and tumor size were assessed. Epidemiologic data were also recorded. All findings were analysed using SPSS 19.0 software. Results: Ampullary (periampullary) carcinomas were much more common than carcinomas of the head of the pancreas, especially in males, with an average age of 53 years. Mean tumor size was 2.5 cms, over 54% were well differentiated. A large majority were pT2 or pT3 and N0. Carcinomas of pancreatic head were also more common in males, mean age was 55 years, mean tumor size was 3.5cms, and over 65% were moderately differentiated. The majority were T2 or T3 and pN1. Prognostically, significant statistical correlation was seen with tumor grade and pathologic T and N stage (p values statistically significant). However, tumor size was not statistically significant. Conclusions: Ampullary carcinomas are more common compared to pancreatic carcinomas. Majority of ampullary carcinomas were well differentiated while majority of pancreatic carcinomas were moderately differentiated. Large majority of both types of cases were pT2 or T3. Histologic tumor grade and pathologic T and N stage are significantly related to prognosis in Pakistani patients with ampullary and pancreatic cancers.

  • Large cell neuroendocrine carcinoma is a rare epithelial neuroendocrine malignancy and is preferentially located in gastrointestinal tract and pancreas. Cases of large cell neuroendocrine carcinoma have been reported in many other locations, including the thymus, gallbladder, prostate, larynx, salivary glands, nasopharynx, tonsil and mastoid. However, primary sinonasal large cell neuroendocrine carcinoma never have been reported in Korea. We experienced a case of primary large cell neuroendocrine carcinoma arising from left maxillary sinus recently. A 82-year-old male patient presented with nasal obstruction and epistaxis. The biopsy revealed large cell neuroendocrine carcinoma with poor differentiation. After a general evaluation, the patient was staged as cT3N0M0. The patient was treated by combined radiotherapy and chemotherapy. We report this rare case with literature review.

  • 췌장암에 대한 근치적 절제술 후에 잔여 췌장에서 발생한 췌장암에 대한 보고는 거의 없는 상태이며, 특히 잔여췌장에 발생한 췌장암에 대하여 반복 췌장절제를 시행한 보고는 더욱 드물다. 저자들은 췌장미부에 발생한 췌장암에 대하여 근치적 절제술을 시행 후 35개월에 잔여 췌장에서 발생한 췌장암으로 췌장십이지장 절제술을 시행한 경우와 췌장두부에 발생한 췌장암에 대하여 췌장십이지장 절제술을 시행 후 20개월 만에 잔여 췌장에 췌장암이 발생하여 췌장미부절제술을 시행한 경우를 경험하였기에 고찰과 함께 보고하는 바이다.

  • 1981년 1월부터 1991년 12월까지 서울대학교병원 치료방사선과에서 방사선치료를 받은 40명의 국소적으로 절제불가능한 췌장암 환자를 대상으로 후향적 분석을 실시하였다. 방사선치료를 2주의 간격을 두고 2000 cGy씩 총 4000 cGy를 조사하고 5-FU (5-fluorouracil)를 방사선조사의 각 course의 첫 3일에 걸쳐 투여한 40명의 모든 환자에 대해 분석을 하였으며 그중 23명의 환자는 방사선치료 4주 후부터 5-FU 단독 혹은 FAN (5-FU, Adriamycin, Mitomycin)을 유지요법으로 시행하였다. 생존의 중앙치는 9개월이며, 2년 생존율은 $10.0\%$이었다. 통증완화는 $70.0\%$에서 완전 혹은 부분관해를 보였다. 치료전 performance status가 중요한 예후 인자였으며 치료전 고식적 수술을 시행한 군 및 종양이 두부에 위치한 군이 의미 있게 생존율이 높았다.

  • The present study has been undertaken to analyze scan manifestations in obstructive jaundice. Scan changes were cprrelated with the duration of jaundice. In addition, clearance rates of trace dose of colloidal radiogold were assessed in each case. The materials were consisted of 19 cases with surgically and/or histopathlogically verified obstructive jaundice from various causes including common duct stone, empyema of the gall bladder and carcinoma of the pancreas head etc. Blood clearance rates of colloidal $^{198}Au$ were determined after the injection of 8 uCi by simple geometrical drawing of recorded strip charts. Scan was performed following additional injection of the same radiogold. In 16 out of 19 cases, the scan revealed rather typical "arborifrom" mottlings around the porta hepatis. The intensity and appearance of such mottlings on the scan was related with the duration of jaundice and level of serum bilirubin and alkaline phosphatase. The blood clearance rates remained to be within normal range in 74 percent of the patients. In the remaining 26 percent, clearance rates ranged between 4.1 and 6 minutes. It is concluded that the association of "arboriform" mottlings and normal or mildly delayed clearance rates in the patients with jaundice is characteristic of obstructive changes in the biliary system.

  • Pancreatic neuroendocrine tumors are rare pancreatic neoplasms comprising 1-2% of all pancreatic tumors and typically present high attenuating mass on arterial and venous phase images, due to their rich capillary network. A 70-year-old South Korean female visited our hospital presenting with jaundice and dark urine color. She had received an operation for treatment of small bowel perforation seven years ago. On physical examination, icteric sclera was observed but otherwise unremarkable. Laboratory tests were abnormal liver function test and suspected obstructive jaundice. Computed tomography revealed 4 cm sized cystic mass lesion with homogeneous low attenuation in the head of pancreas and distal common bile duct was compressed by the mass. During review of past medical records, we found that the mass was observed and measured about 1.7 cm seven years ago. To resolve obstructive jaundice, pylorus preserving pancreaticoduodenectomy was performed and diagnosed with well differentiated pancreatic neuroendocrine carcinoma with intermediate grade.

  • 췌-담도 및 배터 팽대부 주위의 암은 조기진단이 어려워 처음 발견시 질병이 상당히 진행되어 있어, 근치술은 물론 생검진단도 수행하기가 어려운 경우가 흔히 있다. 과거 이런 환자들의 진단 방법의 하나로 십이지장에서 담즙을 얻어 세포병리 검사가 시도 되었었으나, 이 경우 얻어진 담즙에 위액 및 췌액이 섞여 있어 변성을 쉽게 초래하고, 염증세포들이 많이 섞여 있을 뿐만 아니라 주위의 염증으로 비정형 세포변화를 초래하여 진단이 어려운 경우가 흔히 있었다. 최근 이런 환자들에 있어 수반되는 증상인 폐색성 황달의 완화와 방사선학적 진단을 위해 경피 경간 담도 조영술 및 담즙배출술이 시행되고 있는데, 이때 비교적 세포형태가 잘 유지된 담즙을 반복 채취하여 세포 병리검사가 시행된다. 저자들은 이 방법으로 얻어진 담즙의 세포 병리학적 진단 성적을 검토하여 다음과 같은 결과를 얻었다. 총 검체는 148명 환자의 275 검체로 이들의 세포 병리학적 진단은 선암 30예 (20.3%) 편평상피 세포암 1예 (0.75%), 전이성 소 세포암 1예 (0.7%), 선조성 비후 8예 (5.4%) 비정형 6예 (4.1 %), 간 흡충증 17예 (11.5), 양성 질환 57예 (38.5%)였고 28명 (18.9%)에서는 부적합 검체가 의뢰 되었었다. 그중 105명에서 의무기록의 확인이 가능하였는데 이들의 임상진단은 99명에서는 악성 질환 이었고 6명에서는 총 담관 결석과 협착과 같은 양성 질환 이었다. 담즙 세포 병리검사에서의 이들 악성 진단율은 23.2%이었다. 이들 악성 질환을 담도 유래의 종양과(1군)부근 림프절의 전이성암, 췌장암, 배터 팽대부 주위암 등의 외인성으로 담도를 압박하는 종양(2군)으로 나누어 보면 악성 진단율은 각각 37%와 11.6%로 현저한 차이가 있었다. 이들중 조직학적 진단이 가능 하였던 9예의 경우 세포 병리 진단율은 각각 50%(1군)와 20%(2군)로 역시 현저한 차이가 있었다 임상진단이 양성 질환 이었던 예들은 전예에서 세포 병리학적으로 양성으로 진단되어 담즙 세포 병리검사의 임상진단과의 일치율은 27.6%, 특이도는 100%이었다. 이상으로 이 담즙세포 검사의 악성 진단율은 그리높지 않으나, 경피 경간 담즙 배출술로 환자의 증상을 완화 시키면서 부수적으로 진단도 얻을 수 있는 유용한 방법이라 하겠고, 그중 담도유래의 종양군에서 외인성으로 담도를 압박하게 되는 종양군에 비해 현저히 높은 진단율을 보였다.
