the gastrointestinal stromal tumor (gist) is a rare mesenchymal tumor of gastrointestinal (gi) tract. this tumor has tendency to liver metastasis and peritoneal recurrence, however; the primarily lymph node involvement or metastasis is rare. here we reported a 17-years-old girl with multifocal gastric gist and multiple lymph node involvement at presentation and recurrence in celiac lymph nodes....

aim :  this study aimed to compare the recurrence rate, mortality, and morbidity of curative resection of distal adenocarcinoma of the stomach between total gastrectomy (tg) and subtotal gastrectomy (stg). background : the choice between tg and stg for adenocarcinoma of the lower third of the stomach is still a matter of debate and controversy among surgeons. patients and methods : hospital rec...

Juvenile nasopharyngeal angiofibroma (JNA) is a rare, benign and locally invasive tumor. Massive bleeding because of vascularity of tumor and postoperative recurrence are potential problems of management. Endonasal approach reduces the rate of postoperative recurrence, intraoperative bleeding, and complications of surgery, time of operation and duration of hospitalization. In this article, we r...

Background and Aim: Basal cell carcinoma (BCC) is considered to be the most common malignancy in humans and occurs primarily in the skin especially in the head and neck region. Considering the high recurrence rate of the tumor, finding a marker for prediction of recurrence is very important. Cancer stem cells are a small subpopulation in the tumors that are related to tumorigenesis and recurren...

esophageal cancer is a lethal disease with poor survival rate. it is necessary to determine the extension, and the stage of the tumor to predict the outcome of patients. of the two common pathologic types, squamous cell carcinoma is still the most common form, and adenocarcinoma is the leading one. early diagnosis and radical treatment of esophageal cancer, regardless of tumor spreading, increa...

Background: Aggressive angiomyxoma is a rare mesenchymal tumor with extensive local invasion. It often presents with a lump in the perineal area and pelvic. Since it often does not involve adjacent organs such as the urethra and anus, does not cause obstructive symptoms. Its incidence is 6 times higher in women than men. This tumor grows slowly and has a slight tendency to metastasize. However,...
