Introduction: Follicular Lymphoma (FL) is a B-cell neoplasm arising from the germinal center. Gastrointestinal FL rare case, accounting for less than 4% of all primary lymphoma gastrointestinal tract. Duodenal-type (DTFL) was included in an entity intestinal FL. However, 2017 World Health Organization (WHO) Classification, this specific variant called DTFL. In article, we report case DTFL 56-ye...
BACKGROUND AND STUDY AIM Small-bowel tumors account for 1% - 3% of all gastrointestinal neoplasms. Recent studies with video capsule endoscopy (VCE) suggest that the frequency of these tumors may be substantially higher than previously reported. The aim of the study was to evaluate the frequency, clinical presentation, diagnostic/therapeutic work-up, and endoscopic appearance of small-bowel tum...
a set of one hundred and twenty nine patients with known primary malignancy and suspected brain metastasis was reviewed in present study. the patients were selected among patients presented to the mri section of imam khomeini hospital or a private mri center in tabriz (iran). primary tumor site, clinical manifestations, number and site of lesions were identified in this patient population. the ...
BACKGROUND: The identification of all sites of intra-abdominal adenocarcinoma is key to optimal surgical resection and tumor staging. Conventional imaging methods and direct visualization and palpation have limited sensitivity and specificity. Radioimmunoguided surgery (RIGS) has a potential to improve these parameters. METHODS: The development of the RIGS concept is presented, and the studies ...
BACKGROUND Small bowel tumors comprise 25% of gastrointestinal (GI) neoplasms, of which only between 0.2 and 1% correspond to gastrointestinal stromal tumors (GIST). GI bleeding is the most common presentation of GIST, being responsible in 1% of the cases. This type of neoplasm can also be the origin of an intussusception, which is an infrequent process during adult age, representing only 5% of...
BACKGROUND Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal neoplasm of the gastrointestinal tract. GISTs originate from cells of Cajal and related stem cells. Surgery and imatinib therapy are the main lines of treatment. CASE REPORT We report on a case with GIST in the colon treated with surgical resection followed by adjuvant imatinib therapy. This treatment showed no...
Although gastrointestinal stromal tumor (GIST) is the most common mesenchymal neoplasm of the gastrointestinal tract, it rarely arises from the esophagus and is thus very rarely the cause of a mediastinal mass. We report a case of esophageal GIST presenting as a mediastinal mass in a 59-yearold male. If such a tumor has extremely exophytic growth, it may result in a huge mediastinal mass withou...
Inflammatory fibroid polyp or Vanek's tumor of the gastrointestinal tract is a rare, benign neoplasm. The lesion may occur at any age but is commonest in the sixth and seventh decades and is more often found in women. It is mostly situated in the stomach, especially in the antrum. Symptoms depend on the location and the size of the lesion. We present a case of a 67-year-old woman with a large i...
The association of gastrointestinal stromal tumor (GIST), synchronous or metachronous with other tumors is reported in special literature, the most frequent being associated with other gastrointestinal tumors. GISTs are the most common mesenchymal neoplasm of the gastro-intestinal tract with a malignant potential. We present a case of 68-year-old male patient diagnosed with GIST stage IV, unrea...
