Pancreatic Head Tumor

Gastrointestinal stromal tumors (GISTs) are rare mesenchymal tumors of the gastrointestinal tract that originate from theintestinal cells of Cajal(ICC) (Fletcher et al., 2002). Only a few cases have been described with extragastrointestinal stromal tumors (Kim et al., 2012; Soufi et al., 2013; Meng et al., 2011). They are often diagnosed as a pancreatic head tumor as they are very difficult to relate to the duodenum with CT, MRI, or ultrasound. We present a case of a sixty-four-year-old woman who presented with abdominal pain and cardialgia for a follow-up examination after breast cancer surgery. On laparotomy there was a 3 × 5 cm hypervascular mass arising from the pancreatic head with macroscopically no attachment to the duodenum. The patient underwent pancreatoduodenectomy (PD) modified after Traverso-Longmire, histopathology proved a duodenal GIST. This case proves that duodenal GISTs can grow invasively into the pancreas and appear as solid pancreas head tumor; therefore, these tumors should be included into differential diagnosis.

AbstractGastrointestinal stromal tumor (GIST) is defined as mesenchymal tumors of the gastrointestinal tract expressing proto-oncogene protein CD117. They are the most common sarcomatous tumors of the gastrointestinal tract. GISTs are presumed to arise from interstitial cells of Cajal or gastrointestinal pacemaker cells which control gut motility. They have unpredictable biological behavior. Prognosis is dependent on tumor size as well as mitotic count. Radical surgical excision is the treatment of choice. They rarely metastasize to lymph nodes. Imatinib therapy is used as an adjuvant therapy. The follow-up of patients postsurgery is not standardized.

Gastrointestinal stromal tumors (GISTs), the commonest mesenchymal tumors of gastrointestinal tract are often described to take origin from the interstitial cells of Cajal (ICC) or its precursor cells. Rarely these tumors do arise in structures other than the alimentary tract like omentum, mesentery, retroperitoneum, etc., of varying malignant potential and are known as extra-gastrointestinal stromal tumors (eGISTs).This is a case report of a 70-year-old female with multicentric malignant eGISTs arising in the mesentery of ileum. On laparotomy, a large mass of 20 × 15 cm was found in the small bowel mesentery without involvement of the adjacent ileum, with multiple other small nodules resembling lymph nodes, present adjacent to it. Histopathological study of the excised lump, confirmed the mass to be malignant eGIST without involvement of the adjacent ileum, with cluster differentiation (CD)117 positive and of high-risk stratification. The mesenteric nodule was confirmed on histopathology to be malignant eGIST, similar to that of that of the primary, without any lymphoid tissue. Adjuvant imatinib mesylate treatment was started immediately postoperation with the patient doing well at 1 year of follow-up. We report this case, due to the rare occurrence of multifocal malignant eGISTS of small bowel mesentery, which is yet to be reported. The existing literature is unclear regarding the clinicopathology and management of multifocal malignant stromal tumors of the mesentery.

Gastrointestinal Stromal tumors (GIST) are uncommon primary mesenchymal tumors arising from the gastrointestinal tract. The duodenum location is unusual. The authors present a case of duodenal GIST, mimicking a pancreatic tumor. Preoperatively computed tomography (CT) revealed a hypervascular mass of 10 cm in diameter, in the pancreatic head. Endoscopic examination showed erosion in duodenal mucosal with local bleeding. The patient underwent sucessfully pylorus-preserving pancreaticoduodenectomy.

Gastrointestinal stromal tumors (GIST) are the most common mesenchymal tumors of the digestive tract (1%). These tumors express the CD 117 in 95% of cases. The stomach is the preferential localization (70%). Diagnosis is difficult and sometimes late. Progress of imaging has greatly improved the management and the prognosis. Computed tomography (CT) is the gold standard for diagnosis, staging, and treatment follow-up. The increasing recognition of GIST’s histopathology and the prolonged survival revealed some suggestive imaging aspects. Key words: gastro-intestinal stromal tumors; computed tomography; diagnosis

Abstract Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gut and are distinguished by expression of CD117 (c-Kit). Oncogenic mutations in the KIT or PDGFRA gene are detected in approximately 85% of sporadic GISTs. In recent years, examples of familial GIST have been reported in which germline mutations of KIT or PDGFRA result in multiple GISTs, skin disorders, and other abnormalities. The most common germline mutations are in KIT exon 11, mutations in exons 8 and 17 have also been described, and there are 2 families with germline PDGFRA mutations. We present a case in which a germline KIT exon 13 mutation (K642E) was discovered in a patient with multiple GISTs of rectum, small intestine, and esophagus, as well as diffuse hyperplasia of the interstitial cells of Cajal. To our knowledge, this is only the second germline example of this particular mutation. The patient's esophageal tumors were stabilized with imatinib.

Resection Of The Pancreas

The experience of surgical treatment of 154 patients having chronic pancreatitis with preferential injury of the pancreas head which underwent different operative interventions: isolated resection of pancreatic head ( based upon Berger surgery - 24, Frey surgery - 39), pancreatoduodenal resection ( with gastric resection - 22, with preserved pylorus - 43) and drainage surgeries - 26 is presented in the article. The surgery of isolated resection of pancreatic head has less number of nearest unfavorable results compared with pancretoduodenal resection with preserved pylorus. Proximal resection of the pancreas the variants of which are different isolated resection of pancreatic head is superior upon surgeries with full or partly resection of the duodenum due to fast normalization of the motor-evacuation function, less rate of the intestinal reflux and portion character of duodenal evacuation. In the follow-up period after pancreatoduodenal resection, atrophic processes occur in distal areas of the pancreas which are followed by clinical manifestations of exo- and endocrinous insufficiency. The surgery of longitudinal pancreatic jejunostomy does not avoid pathologic changes in the organ head and pain syndrome.

Pancreatic Head Tumor

There have been no reports of ruptured solid pseudopapillary neoplasm (SPN) into adjacent organs. A 22-year-old female was referred to our hospital for treatment of a pancreatic head tumor. Computed tomography (CT) examination at our hospital showed a 5-cm tumor containing air, although CT at a previous hospital revealed an 8-cm tumor without air. Thus, a spontaneous rupture of the tumor into the duodenum was suspected. Subtotal stomach preserving pancreaticoduodenectomy with combined resection of the portal vein was performed. Contrast radiography of resected specimen showed the medium injected into the tumor leaking out from the 2nd portion of the duodenum. Histologically, the patient was diagnosed as SPN. Microscopic invasion to the portal vein and duodenum were also confirmed. She did not experience any postoperative complications and has remained well without any signs of recurrence during 2 years of follow-up. Although there have been 14 studies reporting ruptured SPN, this is the first report of SPN that spontaneously ruptured into the duodenum. An extremely rare case of SPN of the pancreatic head that spontaneously ruptured into the duodenum was reported.

Mesenchymal tumors of the gallbladder are rarely encountered in clinical practice. The Gastrointestinal Stromal tumors(GIST) of the gallbladder are rarely encountered. These tumors most commonly arise from the interstitial cells of cajal(ICC), the pacemakers of the intestinal system. There can be benign as well as malignant form of GIST .The literature on GIST arising from the gallbladder wall is limited to few case reports only.on extensive search of the indexed literature only 9 cases of gallbladder GIST were retrieved. Based on the available literature these tumors are commonly found in females. They usually present with hypochondrial pain with or without other features of cholangitis. These tumors are usually malignant and warrant a radical surgical excision.The data on postoperative adjuvant therapy and survival is limited. The authors are presenting a review of the available literature on this rare pathology.

Pancreatic Head Tumor

The article presents a clinical observation of a patient with type 1 Multiple Endocrine Neoplasia syndrome (MEN 1). During the diagnostic search, a combination of primary hyperparathyroidism, parathyroid adenoma and hormonally inactive pancreatic head tumor was found. Simultaneous transoral parathyroidectomy and laparoscopic resection of the pancreatic head was performed. We haven`t found the literature data describing such kind of operations for MEN 1 syndrome. An original solution was applied to perform intraoperative ultrasonography monitoring. The results of 1-year postoperative follow-up are presented. This observation demonstrates the possibilities of endoscopic technologies in the treatment of MEN 1 syndrome.
