1/4. Intraductal papillary mucinous tumors: a case report and review of literature.Intraductal papillary mucinous tumors are slow growing cystic neoplasms of pancreas with favorable prognosis. A case report of such a tumor in an octogenarian is presented. Excessive mucin secretion with ectatic dilatation of pancreatic ducts is a hallmark of this tumor. K-ras and p53 mutations are less frequent then in ductal pancreatic adenocarcinoma. Endoscopic retrograde cholangiopancreatography findings are diagnostic and include a patulous papilla and amorphous filling defects in dilated pancreatic ducts. Magnetic resonance pancreatography, endoluminal ultra-sound, and pancreatoscopy are also helpful in diagnosis. Complete surgical resection is recommended.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
2/4. Mucinous cystic lesions of the pancreas. Report of a patient submitted to distal pancreatectomy.Intraductal papillary neoplasm consists a variant of the mucin-producing neoplasms of the pancreas; these are rare diseases that can be divided into mucinous ductal ectasias and intraductal papillary neoplasms. Such neoplasms have a malignant potential, and their prognosis is good if they are early diagnosed and localized surgical resection. This paper describes a case of an intraductal papillary neoplasm localized in the tail of the pancreas and treated by distal splenopancreatectomy. The literature on this rare disease is also reviewed.- - - - - - - - - - ranking = 5keywords = neoplasm (Clic here for more details about this article) |
3/4. Cystic sebaceous neoplasms in muir-torre syndrome.Cystic sebaceous neoplasms have been seen only in patients with muir-torre syndrome (MTS) and have recently been characterized as marker lesions of MTS. Histologically, these lesions form a spectrum of tumors ranging from benign cystic adenomas to proliferative cystic sebaceous tumors. We describe 2 proliferative cystic sebaceous tumors in a 53-year-old man whose workup revealed colonic adenocarcinoma and other sebaceous tumors consistent with MTS. Both the chest wall and the left thigh masses were grossly cystic, measuring 1.0 and 1.5 cm, respectively. Histologic sections demonstrated well-circumscribed cystic neoplasms located in the deep dermis and subcutaneous tissue. Each had a focally infolded cyst wall composed of immature basaloid cells with prominent nucleoli and mitoses, consistent with a proliferative cystic sebaceous tumor. Recognition of cystic sebaceous neoplasm by pathologists and communication to clinicians of its strong association with MTS is of diagnostic importance.- - - - - - - - - - ranking = 7keywords = neoplasm (Clic here for more details about this article) |
4/4. Obstructive chronic pancreatitis and/or intraductal papillary mucinous neoplasms (IPMNs): a 21-year long case report.CONTEXT: Intraductal papillary mucinous neoplasms of the pancreas (IPMNs), usually present with a picture of chronic pancreatitis and must be considered within the differential diagnosis of this condition. CASE REPORT: We report a long history of a 58-year-old male who presented with recurrent attacks of pancreatitis. He was treated for chronic pancreatitis until the age of 78 when the diagnosis of IPMN was made, but radical treatment was not possible and he was managed palliatively. The patient died of sepsis and multi-organ failure 21 years following his first presentation. CONCLUSION: This case highlights possible pitfalls in the diagnosis and treatment of IPMNs, suggests a very long natural history, proposes possible palliative treatment in selected cases and reflects about IPMNs biological position in the chronic pancreatitis-ductal adenocarcinoma chain.- - - - - - - - - - ranking = 5keywords = neoplasm (Clic here for more details about this article) |
