PURPOSE: To identify reproducible CT imaging features of small bowel gastrointestinal stromal tumors (GIST) that are associated with biologic aggressiveness. METHODS: Patients with histologically proven small bowel GISTs and CT enterography or abdominopelvic CT were included. Biologic aggressiveness was established based on initial histologic grading (very low risk to malignant), with "malignant" assigned if recurrence or metastases developed subsequently...

Gastrointestinal stromal tumors (GISTs) are the most common type of gastrointestinal mesenchymal tumors, although metastasis to the perigastric lymph nodes is relatively rare, compared with liver or peritoneal metastasis. In this report, we describe a case of stomach GIST with a solitary simultaneous metastasis in the left axillary lymph node. A 68-year-old man was diagnosed with a large upper-stomach GIST, and computed tomography and positron emission tomography revealed masses in the left axilla and right mediastinum...

A 12-year-old, 3.6-kg, spayed female domestic shorthaired cat had a 2-month history of anorexia and weight loss. Abdominal ultrasonography and computed tomography revealed an exophytic mass originating from the jejunum with very poor central and poor peripheral contrast enhancement. On day 14, surgical resection of the jejunum and mass with 5-cm margins and an end-to-end anastomosis were performed. Histopathological examination revealed the mass was a transmural, invasive cancer showing exophytic growth and originating from the small intestinal muscle layer...

Cholangiolocellular carcinoma (CoCC) is a rare primary liver cancer. It is considered to originate from hepatic progenitor or stem cells. We report a rare case of a 74-year-old male with CoCC of the liver and duodenal gastrointestinal stromal tumor (GIST). Both tumors manifested tracer uptakes on F-18 fluorodeoxyglucose positron emission tomography/computed tomography (F-18 FDG PET/CT); however, the uptake in hepatic tumor was extremely higher than that in the duodenal tumor. This finding was helpful to exclude the metastasis of GIST...

Gastrointestinal stromal tumors (GISTs) that lack kinase mutations often show loss of function of the succinate dehydrogenase (SDH) complex, due to germline mutation or promoter hypermethylation. SDH-deficient GISTs are exclusive to the stomach and have a multinodular architecture. It has been suggested that conventional risk stratification criteria may not predict outcome for this group of tumors, although data are limited. Here, we report the clinical, histologic, and genetic findings from a large cohort of 76 SDH-deficient GISTs diagnosed from 2005 to 2015, identified on the basis of histologic features or family history (45 female/31 male; mean age at diagnosis 32 y; range 11 to 71 y; 10 patients 50 y of age or above)...

PURPOSE: KIT mutations, the most prevalent genetic event in gastrointestinal stromal tumors (GIST), are associated with malignant features and poor prognosis. Aggressive GISTs possess a high propensity to spread to the liver. This study aimed to explore the role of KIT mutations in GIST liver metastasis. EXPERIMENTAL DESIGN: A total of 170 GISTs were used to determine the association between KIT mutations and liver metastasis. Immunohistochemistry was performed to assess the correlation of KIT mutations with CXCR4 and ETV1 expression...

BACKGROUND: Hypercalcemia is the most common oncologic metabolic emergency but very rarely observed in patients with gastrointestinal stromal tumour, which is a rare mesenchymal malignancy of the gastrointestinal tract. We describe a case of hypercalcemia caused by elevated levels of activated vitamin D in a patient with gastrointestinal tumour. Prior to this case report, only one paper has reported an association between hypercalcemia, gastrointestinal stromal tumours and elevated levels of vitamin D...

The patient was a 58-year-old man who visited our hospital with a chief complaint of rapidly aggravating feeling of epigastric distension and gastralgia. A giant mass, with a major axis of 22 cm, excluding the upper abdominal organs such as the stomach, liver, and pancreas and containing cystic and solid components was observed on abdominal computed tomography( CT). Laparotomy was performed with the aim of differentiating between a gastrointestinal stromal tumor (GIST) arising from the stomach or omentum and abdominal soft tissue tumors...

Primary hepatic leiomyoma is a neoplasm of mesenchymal origin and occurs only rarely. Secondary to benign smooth muscle proliferation, it is usually found in adult women and is associated with Epstein-Barr virus (EBV) infection. Here, we report the 29(th) case of primary hepatic leiomyoma with its unique features related to diagnosis, treatment and developmental biology. A 48-year-old man, with an immunocompromised status, complained of pain in the upper quadrant of the abdomen. Serological analysis indicated no presence of hepatitis virus, no human immunodeficiency virus, and no EBV infection...

We report a case of hepatic metastasis from gastric gastrointestinal stromal tumor (GIST), which was safely resected with preoperative imatinib therapy. A 60-year-old woman was hospitalized and underwent a treatment for hepatic SOL at another hospital prior to gastric GIST resection. Computed tomography revealed a tumor compressing the right and middle hepatic vein. The tumor volume decreased after an initiation of imatinib therapy aimed at preserving the middle hepatic vein. Although tumor volume was further decreased over the course of twelve months, a new lesion appeared, suggesting a progressive disease...

A 65-year-old man received upper gastrointestinal endoscopy. At that time, no abnormalities were identified in the stomach except for a submucosal tumor approximately 1 cm in maximal diameter at the gastric cardia. Two months later, he developed tarry stools and anemia. Colonoscopy revealed no abnormal findings in the colon or terminal ileum. Upper gastrointestinal endoscopy was re-evaluated in our hospital. Macroscopically, the previously detected submucosal tumor had grown to 3.0 cm in maximal diameter and the tumor was exposed by extensive ulceration...

Carney triad, as originally described in 1977, was the association of 3 tumors: gastric epithelioid leiomyosarcoma [later renamed gastrointestinal stromal tumor (GIST)], extra-adrenal paraganglioma, and pulmonary chondroma. The disorder affected mostly young women and was not familial. We studied the clinical and pathologic features of the gastric neoplasm in 104 patients with the syndrome. Most (88%) were young women (mean age, 22 y), and the usual presentation was gastric bleeding. The tumors, commonly antral-based (61%), were multifocal, and ranged from 0...

BACKGROUND/PURPOSE: Site-dependent profiles of chromosome imbalances (CIs) have been reported in gastrointestinal stromal tumors (GISTs). However, the role of specific CIs in association with metastasis is not clear. METHODS: Thirteen resected liver metastatic GISTs, including seven from the stomach and six from the small intestine, were analyzed using comparative genomic hybridization (CGH). The CIs associated with metastatic risk were assessed by comparing them with those identified in our previous study of 25 primary GISTs, including 14 from the stomach and 11 from the small intestine...
