Background: Ovary is the most common site of non-neoplastic and neoplastic lesions, can appear at any age, leading cause hospitalization surgery. The ovary made up totipotent sex cells multipotent mesenchymal cells. As a result, when it becomes neoplastic, almost type tumor develop. Aims Objectives: aim study was to find out histopathological findings ovarian lesions. Materials Methods: present...

Malignant mixed germ cell tumors,though rare overall, are the most common type of malignant ovarian neoplasms in young and adolescent girls. These tumors are rapidly growing and can metastasize. We report a case of 13-yr-old girl who presented at SHKM GMC, Nalhar, Mewat, Haryana, India in December 2013 with huge abdominal lump of a malignant mixed germ cell tumor comprising both immature terato...

INTRODUCTION Gastrointestinal stromal tumors (GIST) are the most common mesenchymal tumors of the digestive tract. There is an increasing number of literature reports on synchronous occurrence of gastrointestinal stromal tumors and another malignancy of distinct etiology and evolution. The most reported cases include gastric synchronous occurrence of gastrointestinal stromal tumors and adenocar...

The aim of this study was to carry out a retrospective analysis of maxillofacial tumors in children and to present the long-term follow-up results. Our study was performed with a retrospective analysis of 90 patients under the age of 15 years with maxillofacial tumor treated in our clinic between 1985-2002. In addition, treatment modalities and long-term follow-up results of these patients were...

Despite growing evidence indicating that astrocyte elevated gene-1 (AEG-1) plays pivotal roles in tumor progression in various types of human cancers including brain tumors; to date, its role in the regulation of mesenchymal transition is not clear in glioblastoma. In the present study, we investigated the contribution of AEG-1 to stress fiber formation and then the acquisition of mesenchymal c...

BACKGROUND The purpose of this study was to evaluate the frequencies of various types of orbital lesions seen at a comprehensive cancer center in the United States. METHODS In this retrospective case series, we reviewed the medical records of 268 consecutive patients referred to our orbital oncology service for evaluation of an orbital mass between November 1998 and February 2009. Each orbita...

Gastrointestinal stromal tumors (GIST) are rare mesenchymal neoplasms of the gastrointestinal tract with a malignant potential and unpredictable behavior. In the literature a few cases of synchronous development of a GIST and another neoplasia with different incidence, etiology, evolution and prognostic have been described. We report a case of a 61 year old male with a simultaneous occurrence o...

Since the mechanisms of the developmental processes of tumors remain unclear, early detection and early treatment of the tumors is necessary to save patients with malignant tumors. Therapies currently available to patients are surgery, chemotherapy, and radiotherapy. However, there are many patients who cannot be saved by such therapies. In this study, we found the common features of various tu...

The authors present an interesting case of a very rare renal neoplasm, malignant epithelioid angiomyolipoma (AML), which belongs to a family of mesenchymal tumors known as perivascular epithelioid tumors (PEComas). In the modern era, benign renal AML typically presents incidentally; it is most commonly found on a CT scan obtained for other purposes. A minority of patients present with hematuria...
