Abstract:
Solid and papillary epithelial neoplasm of the pancreas(SPENP) is an uncommon low grade malignant tumor histologically distinct from the usual ductal adenocarcinoma and amenable to cure by surgical excision. The main features of SPENP are a peculiar morphology, favorable prognosis, and prediction for women 10 and 40 years of age. In men, the occurrence of SPENP seems to be exceedingly rare. The tumor is usually large at the time of presentation, and surgical excision is the treatment of choice. Gross pathologic examination revealed apparent encapsulation, cystic degeneration, and hemorrhagic necrosis. Microscopically, the tumor was characterized by distinctive solid and papillary patterns. This benign or low-grade malignant epithelial tumor is composed of monomorphous cells variably expressing epithelial, mesenchymal, and endocrine markers. The tumor is known to have good prognosis; although local invasion and infiltration of the capsule may occur. Despite growing recognition of this tumor, its histogenesis remains a matter of controversy i.e. pancreatic ductal cell origin, acinar cell origin, pluripotential cell origin. A 44-year-old male presented with an one-year history of postprandial abdominal pain. Following abdominal ultrasonography, computed axial tomography and angiography, a SPENP suspected. The patient underwent exploratory laparotomy. The tumor was located in the head of pancreas. And thus the patient underwent a pylorus-preserving pancreaticoduodenectomy. His postoperative course was uneventful, and he remains well.
