Solid and papillary cystic neoplasm of pancreas is an uncommon low grade malignant tumor. It is predominant in young female between the second and third decades of life, and amenable to cure by surgical treatment. The authors report two cases of solid and papillary neoplasm of pancreas pathologically verified at Kyung Hee University Hospital. The first case was an 11-years old female patient and the other case was a 12-years old male. Symptoms were abdominal discomfort, nausea and vomiting in both cases and abdominal pain in the female patient. CT finding included a solid and papillary neoplasm of pancreas. The mass was well-demarcated with solid and cystic necrosis components. In the female patient, a large hematoma was found. Gross findings revealed apparent encapsulation, cystic degeneration and hemorrhagic necrosis. Microscopically the tumors were characterized by distinctive solid and papillary patterns of cellular arrangement without local invasion. Both patients were discharged after surgery and followed up without any problem.

Two cases with papillary cystic neoplasm of the pancreas are reviewed and discussed. Up to recently, the tumors have been misclassified as nonfunctioning islet cell tumor or carcinoma, acinar cell carcinoma, papillary cystadenocarcinoma, or pancreatoblastoma. It frequently has been managed with aggressive surgery such as pancreatoduodenectomy. The tumors are well encapsulated and the cut surfaces are characteristically solid and hemorrhagic. Ultrasonography and CT scan are the most useful tools for the diagnosis. The neoplasms usually behave like a very low grade malignancy, so complete removal is the treatment of choice for the tumor arising anywhere in the pancreas. We have a boy and a girl who have papillary cystic neoplasm. The boy was 12 years old and the girl was 14 years old. Both underwent distal pancreatectomy and the progress were uneventful.

Mucious cystic neoplasm of pancreas is a cystic neoplasm composed of columnar, mucin-producing epithelium and is supported by ovarian-type stroma. The key to the cytologic evaluation of pancreatic cystic lesions is to recognize the cytologic components as being diagnostic of a mucin-producing cystic neoplasm, as all of these neoplasms need to be resected. We report the use of fine needle aspiration cytology in the diagnosis of an invasive mucinous cystic carcinoma confirmed by partial pancreatectomy. The cytologic specimen showed a abundant mucin background and sheets or papillae of neoplastic cells. There are mucin-containing columnar cells that show a variable degree of cytologic atypia.

Solid and papillary epithelial neoplasm (SPEN) of the pancreas is a rare tumor with low malignant potentiality that usually occurs in young females. Preoperative evaluation, especially radiologic tests, including ultrasonography and CT scan, is helpful in the diagnosis. These studies demonstrate a well-demarcated large mass with solid and cystic portions, frequently in the tail or body of the pancreas. Complete resection is usually curative, however local invasion and/or metastasis may occur. The authors report a case of a solid and papillary epithelial neoplasm of the pancreatic body in a 14-year old child at St. Benedict Hospital and review the literature.

췌장의 장액성 낭성 종양은 일반적으로 양성 질환으로 알려져 있으나 드물게 악성화를 보이는 사례들이 보고되고 있다. 영운에서 췌장 미부에 발생한 장액성 낭성 종양을 수술로 제거한 후 추적 관찰 중 국소 재발과 함께 간으로의 원격전이가 발생한 증례를 경험하여 보고하고자 한다.

Abdominal hydatid cyst disease mostly involves the liver. Involvement of the pancreas as an isolated primary organ is rare accounting for < 2% of all systemic echinococcosis cases. It mostly involves the head of the pancreas. Symptoms depend on the location, size, and associated complications; therefore, it can have varied presentations including acute pancreatitis. On imaging, it can mimic other common pancreatic cystic lesions like pseudocyst or cystic neoplasm. Accurate preoperative diagnosis is usually difficult and requires a very high index of suspicion even in endemic areas. Herein, a case of primary isolated hydatid cyst of the pancreas that was initially diagnosed and managed as acute pancreatic pseudocyst is reported.

췌장의 고형 유두상 상피종양의 임상 병리학적 특징을 분석하고 면역조직화학적 및 전자현미경적 소견을 바탕으로 종양세포의 기원을 살펴보고자 본 연구를 시행하였다. 1990년부터 1996년까지 영남대학교 의과대학 부속병원에서 체장의 고형 유두상 상피종양으로 진단받은 8례를 대상으로 임상병리학적 특정의 분석과 면역조직화학적 및 전자현미경적 검색을 시행하였다. 8례 모두 여성이었고 연령은 21세에서 54세 사이였고 평균연령은 34세였다. 종양의 위치는 미부(4례), 체부-미부(2례), 체부(1례), 두부(1례)에 각각 발생하였다. 육안적으로 고형성 부위, 출혈과 낭성 변화가 혼합된 피막을 가진 종괴로 평균 크기는 9.3cm였고, 조직학적으로 원형 내지 다각형의 균일한 종양세포가 판상 혹은 유두상 배열을 보였다. 변역조직화학 염색에서 8례(100%)가 ${\alpha}1$-antitrypsin에 양성이었고, 7례(87.5%)가 cytokeratin, 7례 (87.5%)가 progesterone 수용체, 6례(75%)가 vimentin, 그리고 1례 (12.5%)가 synaptophysin에 각각 양성이었다. Estrogen 수용체에 대하여는 전예가 음성 반응을 보였다. 전자현미경 소견상 종양세포의 세포질에는 미토콘드리아가 풍부하였고 효소원 과립과 환충판이 관찰되었고 인접한 세포들 사이에 소관 구조를 닮은 간극이 관찰되어 췌장의 고형 유두상 상피종양은 전능 간세포(totipotent stem cell)에서 기원할 것으로 생각된다.

Although many guidelines for pancreatic cystic neoplasms focus on the management of intraductal papillary mucinous neoplasm of the pancreas (IPMN) at the highest oncological risk, there are many issues that surgeons need to consider at the time to plan the surgical procedures based on characteristics of IPMN subtypes, such as multiplicity of branch duct-IPMN (BD-IPMN) and intraductal spreading of main duct-IPMN (MD-IPMN). For multifocal BD-IPMN, partial pancreatectomy would be selected to remove BD-IPMN with predictors of malignancy, while the other lesions without risk factors can be left, although total pancreatectomy might be considered if the patients have a strong family history of pancreatic cancer. Partial pancreatectomy would be also adequate procedure for MD-IPMN if negative surgical margin for high-grade dysplasia or invasive carcinoma were achieved. It has become to be well-known that patients with BD-IPMN are at increased risk for developing not only IPMN-associated pancreatic ductal adenocarcinoma (PDAC) but also PDAC independent from the IPMN. Hence, the detection of a concomitant PDAC is also an important focus for strategies after resection of BD-IPMNs. Our recent analysis of patients after partial pancreatectomy for MD-IPMN with negative surgical margin identified an unexpected recurrence pattern, which we called "monoclonal skip" recurrence. MD-IPMN seems to be disseminated in the pancreatic ductal systems and MD-IPMN with identical genetic background was detected in the remnant pancreas even in a long time after index surgery. We proposed strategies of postoperative surveillance based on characteristics and natural history of each morphological subtype.
