GISTs range from small incidental stromal nodules to large cystic and solid tumor masses. GISTs show a variety of microscopic patterns and therefore several other tumors enter the differential diagnosis. Fortunately, with an understanding of GIST histology, and with the proper use of ...
Leiomyoblastoma Stromal tumors mesenchymal neoplasm KEY POINTS What is now known as gastrointestinal stromal tumor (GIST) used to be called as gastro- intestinal (GI) smooth muscle tumor: leiomyoma if benign, leiomyosarcoma if malignant, and leiomyoblastoma if with epithelioid histology. ...
GISTs are a subset of mesenchymal tumors and represent the most common mesenchymal neoplasms of GI tract. However, GIST is a recently recognized tumor entity and the literature on these stromal tumors has rapidly expanded. An extensive review of the lite
Fine needle aspiration showed gastrointestinal stromal tumor. The patient underwent an 8cm mass resection of the gastric body via laparotomy. Immuno-histology study showed GIST. After that, the patient recovered well with no recurrence in follow-up. Gastrointestinal stromal tumors are commonly presented...

Histology and immunohistochemical staining revealed the perforated tumor to be a metastatic malignant melanoma and the non-perforated tumor was found to be a gastrointestinal stromal tumor (GIST). The patient was discharged 7 d postoperatively. To the best of our knowledge, this is the first ...

Although a confident diagnosis of GIST can be made on cytology, we believe that grading should be left to histology. 展开 关键词: Gastrointestinal Stromal Tumours Fine Needle Aspiration Cytology Spindle Cells DOI: doi:http://dx.doi.org/ 被引量: 1 ...
The current definition of gastrointestinal tumors (GIST) as CD117-positive mesenchymal tumors of uncertain malignant potential fails to include a number of cases with similar histology. In an attempt to improve the classification of these neoplasms, we conducted an immunohistochemical analysis of 244 me...
Histology confirmed a localized gastrointestinal stromal tumor with a high risk of recurrence, and adjuvant imatinib was recommended. The patient elected to delay adjuvant imatinib until after delivery. The postoperative and antenatal course was favorable, and the patient was followed up by ultrasound ...
