Annular Pancreas (AP) is a rare congenital anomaly that usually presents in childhood with symptoms referable to duodenal obstruction; nonetheless, this condition can manifest in adulthood with abdominal pain, pancreatitis, duodenal ulcer, pancreatic head mass. The Authors hereby discuss a case of AP observed in a 63 year-old patient in which EUS played a decisive role in achieving a certain diagnosis.

Acute pancreatitis (AP) has been recognized as a presentation of patients with pancreatic carcinoma (PC). However, the natural history of patients with PC who present with AP as the first manifestation is largely unknown. The aim of this study was to determine the time between the presentation of AP and diagnosis of PC and what factors should alert the clinician to suspect underlying PC in patients with AP. Nineteen physicians completed the survey forms that encompassed 45 patients with a diagnosis of AP preceding a diagnosis of PC. Information included the patient's age, gender, race, conditions that could account for the AP, criteria for diagnosis of AP, severity of AP, criteria for diagnosis of PC, time between the diagnosis of AP and PC, pathology of the carcinoma, extension of the disease, treatment of PC, and survival after the diagnosis of PC. The study population consisted of 45 patients, 27 (60%) men and 18 (40%) women whose average age was 58 years (range, 32-89). Thirty-eight patients were Caucasian, five were black, one was Japanese, and one Arabian. The number of AP episodes before PC diagnosis ranged between one and 15 (mean + 2 SD). AP was mild in 40 (89%) and severe in five (11%). The time between the onset of AP and the diagnosis of PC averaged 34 weeks (range, 1-52). Symptoms on presentation of AP included abdominal pain 45 (100%), weight loss 15 (33%), and jaundice 3 (7%). CA 19-9 was available in 13 patients, eight of whom had levels >100 at the time AP was diagnosed. Abnormal imaging suggestive of PC was detected by ultrasonography in 17 patients, by computed tomography in 30, endoscopic retrograde cholangiopancreatography in 20, and endoscopic ultrasonography in three. Tissue diagnosis was obtained in 43 of 45 (96%) patients; by surgery in 25 patients, needle aspiration in 14, laparoscopy in one, autopsy in two, and lymph node in one. Pathology revealed adenocarcinoma in 37 patients, squamous cell carcinoma in two, undifferentiated carcinoma in two, islet cell in one, and cystadenocarcinoma in one. Surgical findings in 26 patients included 19 with a nonresectable lesion or metastasis and seven patients with resectable lesion for cure. Thirteen patients (28%) were alive 1 year after the diagnosis of PC. The patients had a mean of two (range, one to 15) episodes of AP before the diagnosis of PC, and this was associated with a delay of 34 weeks from AP to diagnosis of PC. Patients with PC who presented with AP were generally older than 50 years of age and the severity of the pancreatitis was mild. The survival rate of patients with PC who presented initially with AP was >25% at 1 year compared with 20% 1 year overall survival of patients with PC. AP seems to be an early presentation of PC and should be sought in patients with idiopathic pancreatitis.

Diagnosis of pancreatic cancer is made late, and prognosis remains extremely poor. This study was carried out to investigate whether symptoms exist before pain or jaundice that could suggest pancreatic cancer and favor earlier diagnosis. The study involved 305 patients with confirmed pancreatic cancer and 305 controls. All subjects were interviewed personally at least twice about their clinical history; pancreatic cancer patients were asked about any disturbances before abdominal pain or jaundice. Of the 305 pancreatic cancer patients, 151 (49.5%) had some prior disturbances, 108 (35.4%) 6 months or less before pain or jaundice and 43 (14.1%) more than 6 months before. Among the latter, 14 (4.6% of all patients) had had anorexia and/or early satiety and/or asthenia (7-20 months before pain or jaundice), 11 (3.6%) had disgust for coffee and/or smoking and/or wine (7-20 months before), 14 (4.6%) had diabetes (7-24 months before), and four (1.3%) had acute pancreatitis (8-26 months before). Among the controls, the only reports of these symptoms were two (0.7%) cases of asthenia (4 and 6 years earlier), 22 (7.2%) cases of diabetes (of which only two [0.7%] were diagnosed 7-24 months before the interview), and one (0.33%) case of acute pancreatitis (10 years earlier). Apart from acute pancreatitis, all the other differences between patients and controls were statistically significant. In approximately 15% of patients, disturbances existed more than 6 months before pain or jaundice, which, although not specific, could raise suspicion of the possibility of pancreatic cancer. These disturbances could represent the one current opportunity for an earlier diagnosis in a significant minority of pancreatic cancer patients.

Pancreas tuberculosis is a rare diagnosis and is usually associated with miliary spread. Only a few cases are reported in the literature. A female patient was admitted with a history of uncharacteristic abdominal pain, weight loss, weakness, and intermittent fever. CA 19-9 was increased and the CT scan showed an irregular mass in the pancreatic tail. Suspecting the diagnosis of pancreatic cancer, a pancreas tail resection with splenectomy was performed. The histological examination showed pancreas tuberculosis. Mimicking pancreatic cancer or presenting with acute/chronic pancreatitis or obstructive jaundice, the diagnosis of pancreas tuberculosis is very difficult to make and is usually established after surgical treatment. Although pancreas tuberculosis is rare, it should be considered when evaluating a pancreatic mass.

History, physical examination, simple laboratory and radiological tests, and endoscopic retrograde cholangiopancreatography (ERCP) are able to establish the cause of recurrent acute pancreatitis in 70% to 90% of patients. Dysfunction of the biliary and/or pancreatic sphincter, as identified by sphincter of Oddi manometry, accounts for the majority of the remaining cases. The diagnosis may be missed if the pancreatic sphincter is not evaluated. Pancreas divisum is a prevalent congenital abnormality that is usually innocuous but can lead to recurrent attacks of acute pancreatitis or abdominal pain. In select cases, endoscopic sphincterotomy of the minor papilla can provide relief of symptoms and prevent further attacks. A small proportion of patients with idiopathic pancreatitis have tiny stones in the common bile duct (microlithiasis). Crystals can be visualized during microscopic analysis of bile that is aspirated at the time of ERCP. Neoplasia is a rare cause of pancreatitis, and the diagnosis can usually be established by computerized tomography or ERCP. A wide variety of medications can also cause recurrent pancreatitis. ERCP, sphincter of Oddi manometry, and microscopy of aspirated bile should be undertaken in patients with recurrent pancreatitis in whom the diagnosis is not obvious.

Systemic lupus erythematosus (SLE) is an uncommon etiology of pancreatic disease. Up to now, only 3 cases of chronic pancreatitis associated with SLE have been reported in adults. We report the case of a 14-year-old girl with SLE and calcifying chronic pancreatitis. At the age of 4 she was diagnosed with SLE. She presented with several acute exacerbations of SLE that were managed with prednisone and azathioprine. At the age of 9, she was admitted with abdominal pain and elevation of serum amylase and lipase levels; no gallstones were found on ultrasound, and treatment with azathioprine was withdrawn. Thereafter, she developed numerous episodes of acute pancreatitis. Later, an ERCP showed pancreatic calcifications and distortion of the main pancreatic duct, both findings consistent with established chronic pancreatitis. At the age of 14, her condition worsened progressively, and a surgical procedure (corporo-caudal spleno-pancreatectomy) was performed. The pathology specimen showed acinar atrophy and intense fibrosis. After surgery, the patient has remained pain-free and is enjoying a normal life.

Hyperamylasemia has been reported in more than 65% of patients with severe leptospirosis, and the true diagnosis of acute pancreatitis is complicated by the fact that renal failure can increase serum amylase levels. Based on these data we retrospectively analyzed the clinical and histopathological features of pancreas involvement in 13 cases of fatal human leptospirosis. The most common signs and symptoms presented at admission were fever, chills, vomiting, myalgia, dehydratation, abdominal pain and diarrhea. Trombocytopenia was evident in 11 patients. Mild increased of AST and ALT levels was seen in 9 patients. Hyperamylasemia was recorded in every patient in whom it was measured, with values above 180 IU/L (3 cases). All patients presented acute renal failure and five have been submitted to dialytic treatment. The main cause of death was acute respiratory failure due to pulmonary hemorrhage. Pancreas fragments were collected for histological study and fat necrosis was the criterion used to classify acute pancreatitis. Histological pancreatic findings were edema, mild inflammatory infiltrate of lymphocytes, hemorrhage, congestion, fat necrosis and calcification. All the patients infected with severe form of leptospirosis who develop abdominal pain should raise the suspect of pancreatic involvement.

Small pancreatic cancers, intractable diseases, offer the possibility of cure. Can this be true? Through the National Pancreatic Cancer Registry, the Japan Pancreas Society (JPS) has collected 822 cases of invasive cancer with tumors <2 cm in diameter (TS1 pancreatic cancer). Papillary adenocarcinoma and the well-differentiated type of tubular adenocarcinoma are more frequent in TS1 pancreatic cancer than the larger tumors, suggesting that further genetic and phenotypic changes occur during their progression. Patients with TS1 pancreatic cancer presented with abdominal pain, jaundice, and exacerbation of diabetes, while 17.3% of them had no symptoms. Further imaging diagnosis should be employed to detect TS1 pancreatic cancer, but conventional US and ERCP play an important role in the diagnostic process. In this study, of 822 patients with TS1 pancreatic cancer, only 216 patients (26.3%) had T1 tumors because of invasion to adjacent tissue. There were 306 patients (37.2%) with lymph node metastasis, of whom 63 (7.7%) had N3 metastasis that is counted as a distant metastasis. As a result, only 136 patients (16.5%) had stage I disease with a median survival time of 78.2 months and a 5-year survival rate of 58.1%. Small pancreatic cancer does not necessarily mean early pancreatic cancer, and surgery alone is not sufficient to cure this disease.

A 47-year-old woman was admitted to our hospital with complaints of fever, upper abdominal pain, and back pain. The serum amylase, C-reactive protein (CRP), and IgG (especially IgG4) were elevated, and abdominal computed tomography (CT) revealed diffuse enlargement of the pancreas and pseudocysts. Endoscopic retrograde pancreatography (ERP) revealed diffuse irregular narrowing of the main pancreatic duct. Histopathological examination of the pancreatic tissue showed fibrotic change with lymphocytic infiltration. Based on these findings, we diagnosed this case as a case of autoimmune pancreatitis. This case also fully satisfied the diagnostic criteria for autoimmune pancreatitis established by the Japan Pancreas Society in 2002. Few reports have been published on cases of autoimmune pancreatitis complicated by the formation of pseudocysts in the pancreas. We, therefore, report this case here to emphasize that cases of autoimmune pancreatitis can be complicated by the development of pseudocysts.

Since the first description of pancreatoblastoma as a malignant pancreatic tumor of childhood in 1957, approximately 200 cases have been reported. We describe an 18-year-old boy who presented with pain and jaundice and was found to have an abdominal mass. The patient initially presented with abdominal pain. During laparotomy, a 10 x 8 x 8-cm3 tumor was discovered in the pancreatic body and tail, and with 3 cystic masses, 15, 10, and 8 cm in diameter, respectively, involving the right lobe of the liver. Pathologic examination of the resected tumor revealed findings characteristic of pancreatoblastoma. The tumor formed acinar and glandular structures and solid areas and contained many "squamoid corpuscles," a defining feature of pancreatoblastoma. In spite of adjuvant chemotherapy with Adriamycin and gemcitabine, the patient returned 11 months later with several large hepatic masses, invading the pancreatic head and enlarged tracheobronchial lymph nodes. Radiotherapy, transcatheter arterial embolization therapy, and chemotherapy were performed. Unfortunately, the patient died 26 months later from disseminated tumor progression. A review of the literature reveals that pancreatoblastoma in childhood must be considered malignant but usually has a favorable prognosis in contrast to pancreatic neoplasms in adult patients. Biologic study will investigate the molecular biology of this rare tumor. The biology may help define prognosis and therapy for this kind of tumor.
