BACKGROUND Only few case reports of mucinous cystic pancreatic neoplasm containing an undifferentiated carcinoma with osteoclast-like giant cells have been described in the literature. In the majority of cases this unusual association of tumors seems related to a favorable outcome. We present the second case of an indeterminate mucin-producting cystic neoplasm containing an area of carcinoma wi...

BACKGROUND The papillary cystic and solid tumour of the pancreas (PCSTP) is a rare primary neoplasm of unknown pathogenesis typically found in young women. PCSTP is a low-grade malignant tumour, which is often asymptomatic but it may present with abdominal pain. CASE PRESENTATION A 38 year old female patient who presented with one day history of epigastric pain was diagnosed as PCSTP. The pat...

Intraductal papillary mucinous neoplasm (IPMN) is a common pancreatic cystic neoplasm that is often invasive and metastatic, resulting in a poor prognosis. Few molecular alterations unique to IPMN are known. We performed whole-exome sequencing for a primary IPMN tissue, which uncovered somatic mutations in KCNF1, DYNC1H1, PGCP, STAB1, PTPRM, PRPF8, RNASE3, SPHKAP, MLXIPL, VPS13C, PRCC, GNAS, KR...

Two young women, one white and one Chinese, with the rare but increasingly recognised papillary and cystic neoplasm of the pancreas are reported. The initial symptom in both was non-specific abdominal pain which, after investigation, was found to be caused by a pancreatic tumour. One patient did not come to surgery until five years after the initial diagnosis when she developed jaundice. In the...

Drs. Levy and Wiersema have provided an authoritative review of the role of endoscopic ultrasonography in the diagnosis and staging of pancreatic cancer. As outlined in their article, endoscopic ultrasound has emerged as an important tool in the diagnostic evaluation of many patients with suspected pancreatic neoplasms. We concur that endoscopic ultrasound is part of the standard preoperative e...

Metastatic pancreatic malignant melanoma is considered to be a highly aggressive neoplasm, and only few metastasectomies for lesions originating from the skin or the ocular region have been reported. We report a case of resection of pancreatic metastasis of malignant melanoma originating from the nasal cavity. An isolated pancreatic tumor was detected in a 46-year-old man who had undergone prot...

In spite of their rarity, cystic neoplasms of the pancreas are characterized by existing or potential malignancy that cannot be ignored during decisive process with regard to the choice of treatment. Diagnostic difficulties in the differentiation of pancreatic pseudocyst and cystic pancreatic neoplasm can lead to misdiagnosis and inappropriate treatment, since clinical symptoms, preoperative im...

Lymphoepithelial cysts of the pancreas are extremely rare, benign, nonneoplastic cysts that may simulate pseudocysts or cystic neoplasm of the pancreas. Endosonographic and cytologic features of pancreatic lymphoepithelial cysts are poorly characterized because of their rarity. However, appropriate prospective diagnosis of pancreatic lymphoepithelial cysts using endoscopic ultrasound-guided fin...

Pancreatic tuberculosis is rare and can occur in the absence of evidence of tuberculosis elsewhere in the body. Here we review the radiological appearance of pancreatic tuberculosis and compare it with other cystic pancreatic lesions, including common lesions (pseudocysts, serous or mucinous cystadenomas, intraductal papillary mucinous neoplasm) and rare lesions such as solid pseudopapillary tu...
