Tailgut cysts and rectal gastrointestinal stromal tumors (GIST) are rare found in the retrorectal space. congenital malformations resulting from incomplete regression of hindgut during embryogenesis they mostly affect women third to sixth decade life; GIST account for 5% all GIST. Both conditions may present with nonspecific symptoms such as pelvic or anal pain, bleeding weight loss. usually be...

RATIONALE Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors involving the gastrointestinal tract. A small percentage of GISTs may cause acute gastrointestinal bleeding, which requires urgent surgical intervention. PATIENT CONCERNS In this case report, we present a 62-year-old male patient with who was hospitalized due to acute bleeding. DIAGNOSES The patient was...

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...

BACKGROUND Coexistence of gastrointestinal stromal tumor with synchronous or metachronous colorectal cancer represents a phenomenon with increasing number of relative reports in the last 5 years. Synchronous occurence of GISTs with other gastrointestinal tumors of different histogenesis presents a special interest. We herein report a case of GIST in Meckel's diverticulum synchronous with colore...

INTRODUCTION Gastrointestinal stromal tumors (GISTs) are mesenchymal tumors of the gastrointestinal tract, which are characterized in the majority of cases by activating mutations in KIT and platelet-derived growth factor receptor alpha (PDGFRA). The introduction of tyrosine kinase inhibitors has revolutionized the management of patients with metastatic GIST. However, complete surgical resectio...

U mô đệm đường tiêu hóa (Gastrointestinal stromal tumors -GIST) có nguồn gốc từ tế bào kẽ Cajal hay giống (Cajal-like), nằm trong lớp cơ trơn của ống (1). GIST thường xuất hiện ở bệnh nhân (BN) độ tuổi 55- 60 tuổi, hiếm gặp dưới 40 tuổi. Vị trí nhất là dạ dày (60%), ruột non (30%), tá tràng (5%), trực (5%) và thực quản khoảng 1% (2). lý gặp, chiếm 10-20% tổng số trường hợp non, đặc biệt khối u ...

Thick calcification is a rare presentation of gastrointestinal stromal tumor (GIST). Penetration into gastric mucosa and pericolic soft tissue has never been reported. We report a case of gastric GIST with cystic degeneration and thick calcification in an 81-year old female, who presented with hematemesis and severe abdominal pain. Thick calcification of this tumor penetrating into pericolic so...

Gastrointestinal stromal tumors (GISTs) are rare neoplasms of the gastrointestinal tract. Their incidence in the esophagus is 1%-3%. Never has a GIST been documented to directly invade the lung. We report a primary esophageal GIST with direct invasion into the lung parenchyma, presenting predominantly with respiratory symptoms. We include a retrospective literature review. Although the principl...

The term gastrointestinal stromal tumor (GIST) in the description of a specific group of gastrointestinal nonepithelial tumors lacking the microscopic evidence of smooth muscle or characteristics of neural immunoreactivity was first introduced by Mazur and Clark (Mazur & Clark, 1983). The common origin of GIST and interstitial cell of Cajal (ICC), the pacemaker cells in the digestive tract, was...

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal neoplasms of the gastrointestinal tract. Their most common metastatic sites are the liver and the peritoneum, but GISTs rarely metastasize to the bones. We report a case of a 58-year-old man with sternoclavicular joint metastasis from a GIST manifesting 28 months after surgical resection of the small intestine tumor. We wil...
