REVIEW
Sun-Young Jun, Seung-Mo Hong
Nonductal pancreatic neoplasms, including solid pseudopapillary neoplasms, acinar cell carcinomas, and pancreatoblastomas, are uncommon. These entities share overlapping gross, microscopic, and immunohistochemical features, such as well-demarcated solid neoplasms, monotonous cellular tumor cells with little intervening stroma, and abnormal beta-catenin expression. Each tumor also has unique clinicopathologic characteristics with diverse clinical behavior. To differentiate nonductal pancreatic neoplasms, identification of histologic findings, such as pseudopapillae, acinar cell features, and squamoid corpuscles, is important...

Here we report the first case of neutrophilic dermatoses related to a granulocyte colony-stimulating factor (GCSF)-producing solid pseudopapillary tumour (SPT). The patient was a 39-year-old woman presenting with scattered pustules and crusts of the palms/heels/thighs and plaques of the bilateral lower legs. The skin biopsy revealed dense neutrophil infiltration in the epidermis to the corium. A pancreatic head tumour was detected on computed tomography. A pathological examination of the resected specimen suggested a SPT...

Solid pseudopapillary tumor (SPT) of the pancreas is a pathological entity rarely encountered in children. Despite its malignant characteristics, SPT has a favorable clinical prognosis. This tumor is more frequently observed in females and is commonly localized in the tail and body of the pancreas. This is the case report of a 9-year-old female patient who presented with severe abdominal pain of sudden onset and vomiting following blunt abdominal trauma. Upon physical examination, abdominal distension, tenderness and abdominal guarding were detected...

PURPOSE: While pancreaticoduodenectomy (PD) has been extensively studied in adults, there are few data pertaining specifically to pediatric patients. We retrospectively analyzed PD-associated morbidity and mortality in pediatric patients. METHODS: Our analytic cohort included all consecutive patients ≤18years of age treated at our institution from 1993 to 2015 who underwent PD. Patient data (demographics, disease characteristics, surgical and adjuvant treatment, length of hospital stay, and postoperative course) were extracted from the medical records...

BACKGROUND Solid pseudopapillary tumor of the pancreas (Frantz tumor) is a rare, low-grade malignant neoplasm. Laparoscopic pancreatoduodenectomy is a good approach for tumors located in the pancreatic head. We present two successful cases in young women. CASE REPORT A 19-year-old woman was admitted to Department of Digestive Surgery due to epigastric pain, nausea, and vomiting. Computed tomography scan of the abdomen was performed, and a 3.0×2.2 cm solid tumor localized in the head of the pancreas was observed...

Epithelial cyst in an intrapancreatic accessory spleen (ECIPAS) is exceedingly rare with only 57 cases reported since the first publication in 1980. Comprehensive clinical and diagnostic features remain to be clarified. We present a case of ECIPAS in a 21-year-old Philippine woman who was admitted with right upper quadrant abdominal pain. A cystic lesion in the pancreatic tail was discovered and evaluated by computed tomography and magnetic resonance images. Based on clinical and radiological features a solid pseudopapillary neoplasm was suspected...

Serous cystic neoplasms (SCNs) are benign cystic neoplasms that predominantly occur in the tail of the pancreas in elderly women. It is well known that patients with von Hippel-Lindau syndrome can develop SCNs and neuroendocrine tumors in the pancreas. However, our understanding on SCNs accompanying other pancreatic tumors (SCNAOPTs) is limited. We compared the clinicopathologic features of 15 surgically resected SCNAOPTs with 259 conventional SCNs. The prevalence of SCNAOPT was 5%. The SCNAOPTs were significantly smaller than conventional solitary SCNs, and they were more commonly observed in the head of the pancreas, while conventional solitary SCNs were more frequently noted in the body and tail...

Pancreatic cystic neoplasm(PCN) are common and increasingly detected in recent years including serous cystic neoplasms, mucinous cystic neoplasms, intraductal papillary mucinous neoplasms, solid pseudopapillary neoplasms and cystic pancreatic neuroendocrine tumors.Some of PCN have a low risk of malignancy while others have a high risk and need interventions, even in the same type of cystic neoplasms. The management of PCN requires risk stratification for malignant potential, and clinicians should have a systematic approach for establishing a diagnosis and determining which patients require surgical treatment...

Background. Solid Pseudopapillary Tumours of the pancreas are a rare entity and more commonly seen in women than in men. These tumours have typically reached large sizes when clinically detected. Case Description. A 21-year-old male was found to have a left hypochondrial mass on physical examination following a trivial soft tissue injury. Contrast-enhanced computed topography (CT) of the abdomen showed a 10.3 × 7.6 × 10.3 cm size arising from the body and the tail of the pancreas. He underwent laparoscopic resection of distal pancreatic tumour en bloc with spleen...

BACKGROUND AND AIMS: Currently, 3 guidelines are available for the management of pancreatic cysts. These guidelines vary in their indication for resection of high-risk cysts. We retrospectively compared the final pathological outcome of surgically removed pancreatic cysts with the indications for resection according to 3 different guidelines. METHODS: Patients who underwent pancreatic resection were extracted from our prospective pancreatic cyst database (2006-present)...

Solid pseudo-papillary tumour of pancreas is a rare neoplasm having a low malignant potential. It mostly affects young adolescent females. We report an unusual case of an 18 year old male with a mass in the mesocolon which was reported as solid pseudo-papillary tumour of pancreas. This case is unusual by virtue of extra pancreatic location and male gender of the patient.

Solid pseudopapillary tumours of the pancreas are rare tumours of uncertain etiology which mostly affects young women. Their prognosis is good especially after complete resection. We report a new case of a young woman; abdominal pain revealed solid pseudopapillary tumour. The diagnosis is based on histological examination associated with immunohistochemistry of the piece of resection removed with caudal splenopancreatectomy.

Lyn A Smith, Colin J McKay
The widespread use of cross-sectional imaging has led to an increased frequency of incidentally detected pancreatic cysts. Neoplastic cysts such as mucinous lesions and solid pseudo-papillary neoplasms have malignant potential and therefore the early detection of these lesions presents an opportunity for prevention or early detection and management of pancreatic adenocarcinoma. Serous neoplastic lesions and non-neoplastic pancreatic cysts such as pseudocysts or walled off pancreatic necrosis and are not associated with malignant potential...

A 59-year-old man was admitted to our hospital for treatment of a 45 mm pancreatic mass found during a medical examination. Endoscopic ultrasound-guided fine-needle aspiration cytology showed polygonal cells with pseudopapillary structures. The tumor cells were positive for nuclear/cytoplasmic β-catenin and CD10, and negative for chromogranin A. After a tentative diagnosis of a solid pseudopapillary neoplasm, middle pancreatectomy was performed. Histologically, polygonal cells with abundant eosinophilic cytoplasm formed in the trabeculae and were immunohistochemically positive for HepPar1 and protein induced by vitamin K absence or antagonist-II...

BACKGROUND: Solid pseudopapillary neoplasms of the pancreas (SPN) are rare tumors affecting mainly women. They show an activating mutation in CTNNB1, the gene for β-catenin, and consequently an overactivation of the Wnt/β-catenin pathway. This signaling pathway is implied in the pathogenesis of various aggressive tumors, including pancreatic adenocarcinomas (PDAC). Despite this, SPN are characterized by an unusually benign clinical course. Attempts to explain this lack of malignancy have led to the discovery of an aberrant expression of the transcription factor FLI1 in SPN...

BACKGROUND: Solid pseudopapillary neoplasms (SPNs) of the pancreas are uncommon neoplasms and are potentially malignant. Complete resection is advised due to rare recurrence and metastasis. Duodenum-preserving pancreatic head resection (DPPHR) is indicated for SPNs located in the pancreatic head and is only performed using the open approach. To the best of our knowledge, there are no reports describing laparoscopic DPPHR (LDPPHR) for SPNs. METHODS: Herein, we report a case of 41-year-old female presented with a 1-week history of epigastric abdominal discomfort, and founded an SPN of the pancreatic head by abdominal computed tomography/magnetic resonance, who was treated by radical LDPPHR without complications, such as pancreatic fistula and bile leakage...

BACKGROUND: Solid-pseudopapillary neoplasms are rare pancreatic neoplasms with low malignant potential that predominantly arise in young women. We sought to characterize this population and the evolving trend at our institution towards laparoscopic management. METHODS: We identified all patients at our institution that were surgically treated for solid-pseudopapillary neoplasm from 2008-2015. Demographic and clinical information were queried from the medical record, and descriptive statistics were performed...
