65 years-old female patient affected by breast cancer (diagnosed in 2005); two family members (father and cousin) died of pancreatic cancer. The patient underwent a magnetic resonance cholangiopancreatography (MRCP) to exclude the presence of a pancreatic tumor. In MRCP multiple small cysts communicating with the main pancreatic duct were seen. The patient decided to undergo a prophylactic total pancreatectomy. The specimen was sectioned in 0.5 cm thick slices. At gross inspection multiple 0.1-1.3 cm cysts were seen throughout the pancreas, some of them filled with mucinous material. No suspicion of cancer. The histological images shown here are taken from the largest cyst, which was found in the pancreatic head above the ampulla.

An abdominal mass was detected in a 65 year-old woman, who presented with upper abdominal dsicomfort. Imaging studies showed a multi- and microcystic tumor mass in the tail of the pancreas. The tumor was resected and presented as a nodular and well-demarcated mass, 11 cm in greatest dimension. The cut surface of the tumor was reddish and soft with multiple microcysts between solid areas. The cysts were filled with serous fluid. |

A 26 years-old female patient, who presented sudden lower
abdominal pain. Gynecological status normal except lower left-sided
abdominal tenderness upon palpation (normal delivery six months ago).
Abdominal ultrasound showed a 15 cm cystic expansion that is attached to
the pancreas and extends to left abdominal cavity. CA19-9 and CEA were
within normal range. Computer tomography scan showed a 13x9x9 cm
multicystic fluid containing retroperitoneal mass that is attached to the tail of the pancreas, which was interpreted as an unusual pseudocyst or
lymfangioma/lymfangiomyoma. A cystic 20x13x10 cm retroperitoneal mass
was removed three months later, which macroscopically showed sponge-like
appearance (Snapshot 1). The specimen contained tail of the pancreas and
spleen (280 g) that were attached to the tumor. |

A 61 year-old man with mild hepatomegaly and slight abdominal pain in the right hypochondrium. Computed tomography scans showed a large cystic mass (20 cm Ø) in the right hepatic lobe with.a mural nodule of 6,5 cm in diameter and thick irregular walls.
2 months later the cystic lesion was resected (bisegmentectomy: segment V and VI). No others tumor was found outside the liver.
Macroscopically, the excised mass consisted of an unilocular cystic lesion, 20 cm Ø, with haemorrhagic, thick irregular walls. A mural nodule, 6,5 cm Ø, with spongy-like appearance was present. Circulating slides from the mural nodule. |

A 49 year-old man was followed for a sclerosing cholangitis revealed by an episode of obstructive jaundice 16 months ago. Imaging results were in favor of such diagnosis with a predominant involvement of intrahepatic biliary tree. No chronic inflammatory bowel diseases were noted. A cholangitis occurred after an endoscopic retrograde cholangiopancreatography and an attempt of stent insertion. Due to the increase of jaundice, an orthotopic liver transplantation was performed.
Liver sections from the right and left lobe showed white, friable and papillary granular intraductal masses. The liver parenchyma exhibited a severe cholestatic pattern and 3 centimetric white nodules were present at distance of the hilum.
The selected slide corresponds to the polypoid endobiliary tumor of the hilum. |

A 54 year-old female developed abdominal tenderness with dyspepsia. Physical examination was unremarkable. There was no history of alcohol intake or pancreatic disease. Ultrasound and CT scan examination demonstrated a unilocular cystic lesion in the tail of the pancreas consistent with cyst neoplasia. The patient underwent distal pancreatectomy.
Macroscopically, the tail of the pancreas presented with a well circumscribed unilocular cystic lesion measuring 9 cm in greater dimension, separated from a normal pancreatic parenchyma by a fibrous pseudocapsule. The wall of the cysts was focally thick for the presence of white-yellow areas; the intracystic fluid was hemorrhagic. The internal surface of the cyst was smooth. The cystic lesion did not communicated with the main pancreatic duct, which presented a regular size. |

A 60-year-old woman symptomatically presented with abdominal discomfort. Abdominal US revealed a large cystic mass, measuring 120 mm in diameter, in the liver. Radiologically, the tumour showed a multiloculated cystic appearance with septation. Solid mural nodules were also identified. CA19-9 and CEA were within normal range. The tumour was surgically resected. |

In magnetic resonance imaging (MRI) suspicion of pancreatic cancer with infiltration and obstruction of the portal vein and liver metastases. Explorative laparotomy, three frozen sections submitted to histopathological analysis for diagnosis confirmation.

Presented by: Johanna Delladetsima, Athens , Greece
A 37-year-old man presented with gradually progressive jaundice and pruritus over the last 5 days. His medical and family history was non significant and he had not received any medications or herbals. He has been consuming ~ 320 g of alcohol twice/week. Moreover, he had been an occasional cannabis user and cocaine inhaler for a 5-month period until 2 months before the icteric episode.
At presentation, there was no evidence of splenomegaly or ascites. Laboratory findings showed normal white and red blood cell counts. Liver function tests displayed a predominant cholestatic pattern (t.bilirubin 9.87mg/dL, ALP 315 IU/L, GGT 1082 IU/L) and elevated aminotransferase levels (AST 122 IU/L, ALT 245 IU/L). Prothrombin time and serum albumin were within normal limits. Acute phase proteins were elevated. Serological markers of hepatitis A, B and C, anti-HIV1,2 and IgM for CMV were undetectable. Tests for autoantibodies (ANA, anti-ds-DNA, AMA, ASMA, p- & c-ANCA) were negative. IgG, IgA, IgM values and protein electrophoresis were normal.
Magnetic resonance cholangiography (MRCP) did not show any extra-hepatic or intra-hepatic lesions, bile duct dilatation or stenosis. Esophago-gastroduodenoscopy and colonoscopy did not reveal any signs of inflammatory bowel disease.
After histological diagnosis, therapy was initiated with methyl-prednisone and ursodeoxycholic acid. One week later, clinical and laboratory improvement was observed. The patient remains asymptomatic, without any rise of aminotransferases or markers of cholestasis, 6 months after completion of therapy.
