introduction: malignant mesenchymal tumors of the larynx are rare. one type of malignant mesenchymal tumor is synovial sarcoma with unknown histogenesis, which occurs predominantly in the lower extremities of young adults. the head and neck region is a relatively rare location. there are few cases of malignant mesenchymal tumors with laryngeal localization in literature. case report: in this r...
Abstract Gastrointestinal mesenchymal tumors are a group of tumors originating from the mesenchymal stem cells of the GI tract. Digestive tract Schwannomas are rare mesenchymal tumors which occur most frequently in the stomach. We report a 56-yearold woman who was examined endoscopically for dyspepsia which she had suffered from since 3 years ago. Around gastric antral mass was seen. Surgical ...

Background: Gastrointestinal mesenchymal tumors are classified as tumors that originate from smooth muscles. Gastrointestinal stromal tumors (GIST) are the most common types of the proposed tumors and can be seen in the GI tract from the esophagus to the anus, but they are mostly seen in the stomach. Mostly from the stomach and asymptomatic, the majority of patients would benefit from surgery a...
objective: gliomas are the most common primary brain tumors, and have been ranked as the fourth leading cause of cancer death. tumor mesenchymal-like stem cells (tmscs) contribute to the aggressive behavior of glial tumors by providing a favorable microenvironment for the malignant cells. the aims of our study were to identify differential proteome of tmscs derived from low vs. high grade gliom...
Background & Aim: Gastrointestinal stromal tumors(GISTs) are the most common mesenchymal tumors of gastrointestinal tract. They are known to express c-kit, which is important in their diagnosis and treatment. The aim of our study was to assess the morphologic and immunohistochemical features of gastrointestinal stromal tumors and the significance of c-kit expression in them. Materials and M...
Primary mesenchymal tumors of the colon are extremely rare tumors among soft tissue sarcomas. These tumors are more aggressive and have poorer prognosis than adenocarcinoma of the colon. Here, we presented 3 cases of primary mesenchymal tumors of the colon. Their histopathological diagnoses are leiomyosarcoma, pleomorphic liposarcoma, and desmoplastic small round cell tumor, respectively. The r...
Odontogenic tumors, derived from epithelial, ectomesenchymal, and/or mesenchymal elements of the tooth-forming apparatus, constitute a heterogeneous group lesions, including hamartomas, benign and malignant neoplasms with metastatic capabilities. This review provides comprehensive overview molecular events in pathogenesis odontogenic tumors. The reasonable better understanding components may pr...
