Pancreatic Schwannoma

Pancreatic schwannomas are uncommon. About 60% of pancreatic schwannomas develop cystic lesions, and the differential diagnosis from other cystic pancreatic tumors is difficult. A 43-year-old man presented for evaluation of liver dysfunction detected during a medical checkup. Blood testing detected obstructive jaundice. A computed tomography scan revealed a well-defined polycystic tumor of about 5 cm at the pancreatic head. We performed surgical resection to treat the patient’s symptoms and facilitate long-term management. Histopathological examination revealed spindle-shaped cells. Immunohistochemical studies showed S100 protein expression and the absence of CD34 and c-kit protein expression. Finally, we diagnosed a schwannoma. Pancreatic schwannoma is usually asymptomatic. The present case presented with obstructive jaundice, which is reportedly a rare symptom. Pancreatic schwannomas should be considered as a differential diagnosis of pancreatic cystic tumors. Dilatation of the pancreatic duct and the 18-fluorodeoxyglucose positron emission tomography findings are important for the differential diagnosis.

Pathologic Classification

Abstract Context.—Cystic lesions of the pancreas are being recognized with increasing frequency and have become a more common finding in clinical practice because of the widespread use of advanced imaging modalities and the sharp drop in the mortality rate of pancreatic surgery. Consequently, in the past 2 decades, the nature of many cystic tumors in this organ has been better characterized, and significant developments have taken place in the classification and in our understanding of pancreatic cystic lesions. Objective.—To provide an overview of the current concepts in classification, differential diagnosis, and clinical/biologic behavior of pancreatic cystic tumors. Data Sources.—The authors' personal experience, based on institutional and consultation materials, combined with an analysis of the literature. Conclusions.—In contrast to solid tumors, most of which are invasive ductal adenocarcinomas with dismal prognosis, cystic lesions of the pancreas are often either benign or low-grade indolent neoplasia. However, those that are mucinous, namely, intraductal papillary mucinous neoplasms and mucinous cystic neoplasms, constitute an important category because they have well-established malignant potential, representing an adenoma-carcinoma sequence. Those that are nonmucinous such as serous tumors, congenital cysts, lymphoepithelial cysts, and squamoid cyst of pancreatic ducts have no malignant potential. Only rare nonmucinous cystic tumors that occur as a result of degenerative/necrotic changes in otherwise solid neoplasia, such as cystic ductal adenocarcinomas, cystic pancreatic endocrine neoplasia, and solid-pseudopapillary neoplasm, are also malignant and have variable degrees of aggressiveness.

Pancreatic cancer is among the most aggressive human cancers, with few symptoms and clinical findings until it is detected in an advanced stage. Today, the only favorable treatment is surgical resection before progression to an invasive stage. There are a variety of benign and premalignant conditions of the pancreas that may appear similar to malignant tumors; early detection and management of those premalignant pancreatic lesions may provide a significant improvement in patient outcome. This review covers cystic neoplasms of the pancreas, premalignant solid lesions of the pancreas, and inflammatory lesions of the pancreas. Figures show a 30 mm diameter hypoechoic lesion without septae in the pancreatic head, an oval 20 mm diameter pancreatic mass with mixed solid and cystic components, a 24 mm diameter hypoechoic mass with well-defined borders in the tail of the pancreas, a 22 × 18 mm cystic lesion with a thick wall and internal debris in the head of the pancreas, and an endoscopic cyst gastrostomy after balloon dilation. Tables list World Health Organization (WHO) 2010 classification of pancreatic tumors, classification of pancreatic cystic lesions, main characteristics of common pancreatic cystic lesions, high-risk stigmata and worrisome features of intraductal papillary mucinous neoplasm on cross-sectional imaging, and WHO classification of pancreatic neuroendocrine tumors.   This review contains 5 highly rendered figures, 5 tables and 55 references

First Case

Introduction: Pancreatic cysts are common (2.5%). Cystic neoplasms represent 10% of cystic lesions and 1% of pancreatic tumors. However, it is difficult to differentiate benign cyst from malignant cystic lesions preoperatively.Objective: To study the cases of pancreatic cystic lesion who underwent various forms of pancreatic resection.Materials and Methods: Nine cases of pancreatic cystic lesion who presented to Kathmandu Medical College Teaching Hospital, Surgical Unit 3 within December 2014- November 2015 were evaluated. Four pancreatic cysts who underwent resection are discussed whereas not managed with resection are excluded.Results: There were 4 cases of pancreatic cyst who underwent pancreatic resection. First case underwent pancreaticoduodenectomy for pancreatic mucinous cystadenoma. However histopathological examination revealed a serous cystadenoma. In second case, pancreatic neck lesion suspected to be mucinous cystadenoma or pseudocyst in MRCP, with negative malignant cells in EUS guided FNAC underwent Central pancreatectomy and was found to be serous cystadenoma. The third case with suspected pseudocyst underwent Pancreaticoduodenectomy after a 3X2 cm2 cystic mass was felt at the posteroinferior side of pancreatic head and malignancy was suspected intraoperatively . HPE report was mucinous cystadenoma. The fourth case with pancreatic pseudocyst at tail with duct calculi and chronic pancreatitis underwent distal pancreatectomy with splenectomy with Frey’s procedure.Conclusion: Management of pancreatic cystic lesion is challenging. Though radiological imaging has limited role in accurate diagnosis, endoscopic ultrasound may be of some benefit.

Primary Pancreatic Lymphoma

Primary pancreatic lymphoma is an extremely rare tumor of pancreas which clinico-radiologically mimics with pancreatic adenocarcinoma. The disease is diagnosed often after radical resection of pancreas. We report a case of 63 years old Chinese gentle man with diagnosis of Primary pancreatic lymphoma who was diagnose after surgical resection. Primary pancreatic lymphoma should also be considered as differential diagnosis in pancreatic tumors. There can be some radiological clues but accurate diagnosis depends on histopathological examination. Definitive treatment still remains controversial.

Langerhans cell histiocytosis (LCH) of the CNS is a rare entity, known to involve primarily the hypothalamicpituitary region, with the clinical hallmark of diabetes insipidus. There have been a few reports of CNS LCH involving the brainstem as intraparenchymal enhancing lesions, but this has never been the presenting complaint of LCH. The authors report on a 7-year-old boy who presented with right cerebellopontine syndrome, in whom a well-defined, solid, enhancing lesion in the brainstem was diagnosed. Clinicoradiological differential diagnosis included glioma and tuberculosis. Biopsy revealed atypical histiocytes positive for CD68, CD1a, and S100 protein; these are the diagnostic features of LCH on histopathological examination. The rapid growth of the lesion was controlled with a chemotherapeutic regimen of cladribine.

The incidence of focal lesions in the spleen is 3.2–4.2% per 100,000 population. Spleen cysts are rare (incidence 0.75 per 100,000). These are single or multiple, thin- and smooth-walled cavities filled with a transparent liquid. Distinguish between primary (or true) cysts, lined with epithelium, and secondary (or false), devoid of epithelial lining. Among the primary cysts, there are congenital cysts formed in the embryonic period due to the migration of peritoneal cells into the spleen tissue, dermoid and epidermoid cysts. A special group of primary cysts are parasitic cysts. Cystic tumors of the spleen include lymphangioma and lymphoma.The main difficulties in the diagnosis and differential diagnosis of cysts and cystic tumors of the spleen are associated with the rarity of this pathology and, as a consequence, a small number of works, including a significant number of the cases. However, in those works where a large number of the cases are described, most often this is one morphological form and an analysis of its various characteristics.Purpose. Based on the analysis of our own examination data of a significant number of patients with cysts and cystic tumors of the spleen, to assess the possibility of differential diagnosis of individual morphological forms according to ultrasound data.Materials and methods. 323 patients with cysts and cystic tumors of the spleen from 15 to 77 years old (men – 105 (32.5%); women – 218 (67.5%) were treated at A.V. Vishnevsky National Medical Research Center of Surgery for the period from 1980 to 2020. All patients underwent ultrasound during examination. Surgical treatment was carried out in various ways – (85.1%), when making a preoperative diagnosis of an uncomplicated spleen cyst of small size, dynamic observation was carried out (verification by puncture biopsy data).Results. Morphological verification of cysts and cystic tumors of the spleen was presented as follows (taking into account possible difficulties in identifying the epithelial lining): true cyst – 182 (56.4%); dermoid cyst – 3 (0.9%) (malignant – in 1 case); pseudocyst – 16 (5.0%); pancreatogenic – 34 (10.5%); echinococcus – 52 (16.1%); lymphangioma – 24 (7.4%); lymphoma – 10 (3.1%); ovarian cancer metastasis – 2 (0.6%). The article describes the ultrasound signs of the above forms of the lesions with an emphasis on the complexity of diagnosis.Conclusions. Primary and parasitic spleen cysts are well differentiated according to ultrasound; false cysts of the spleen, depending on the cause of their occurrence, can create difficulties in their identification and differentiation (they require careful dynamic control); cystic tumors of the spleen should be differentiated from malignant tumors and metastases of a cystic structure, as a result of which such vigilance should always be present when they are detected.

Differential diagnosis of globus sensation in an otherwise asymptomatic patient should include hypopharyngeal fibrovascular polyp to avoid potentially fatal complications like airway compromise following regurgitation. We present a case of a 74-year-old man with a 13-cm long hypopharyngeal fibrovascular polyp with 9 months history of globus sensation. A narrow stalk of the giant polyp allowed endoscopic removal and complete resection with the CO2 laser. Histopathological examination was conclusive for the fibrovascular polyp.
