Neuroendocrine neoplasms (NENs) predominantly arise within the intestinal tract, pancreas, and lung, but may develop in various organs commonly metastasize, especially to liver. Cross-sectional imaging (ultrasound, computed tomography, magnetic resonance imaging) play a central role detection, characterization, management, follow-up of NENs. Imaging features tumors significantly vary as per sit...

Gastrointestinal stromal tumor (GIST) is a rare cancer of the gastrointestinal tract, it occurred about 0.1-3.0% all neoplasms. Accounted 10% small-bowel tumors, and 10-15% sarcomas. Liver common hematogenous spread in GIST. However, metastasis to lymph nodes consider extremely routine node dissection for GIST was not recommended. Hence, we reported case series that metastasize along our experi...

We report the case of a 64-year-old woman with a gastrointestinal stromal tumor and a diffuse large cell lymphoma. For this case, we conducted a literature review in an attempt to correlate these two neoplasms on a molecular basis. Diffuse large cell lymphoma is a subtype of non-Hodgkin lymphomas. The etiologic factor of these lymphomas is considered to be the mutations or allelic losses of the...

UNLABELLED Gastrointestinalstromal tumors are rare neoplasms and represent 0,1% to 3% of all gastrointestinal cancers. They are the most frequent mesenchymal neoplasms of the gastrointestinal tract with a malignant potential and unpredictable behavior. The synchronous association with other primary gastrointestinal carcinoma has been rarely reported in the literature with increasing number in t...

Gastroduodenal intussusception is an infrequent cause of gastrointestinal obstructive disease. Benign neoplasms, gastrointestinal stromal tumors and pedunculated adenocarcinomas of less than 5 cm have been reported to cause gastroduodenal intussusception. We report a case of 76-year-old woman who was presented with a 3-day history of nausea and vomiting due to upper gastrointestinal obstruction...

Gastrointestinal stromal tumor (GIST) is a rare form of mesenchymal tumor of the gastrointestinal tract, accounting for 1% of malignant neoplasms [1]. Most gastrointestinal mesenchymal tumors are GISTs, originating from interstitial cells of Cajal or precursors of these cells. Although several reports regarding GIST have incrementally advanced our understanding of this condition in recent years...

INTRODUCTION Testicular neoplasms metastasizing to the retroperitoneum rarely involve the upper gastrointestinal tract. Gastrointestinal tract metastases usually present with complications including intestinal obstruction, gastrointestinal hemorrhage, and rarely ulceration of the bowel mucosa. CASE PRESENTATION We describe an unusual case of duodenal perforation as the presenting manifestatio...

Gastrointestinal stromal tumors are mesenchymal neoplasms of the gastrointestinal tract that represent less than 1% of all GI tumors. Here the case of such a tumour that, in addition to the classical features, also displayed chondroid differentiation is reported. Chromosomal abnormalities were also investigated.
