OBJECTIVE The Dabska tumor is a rare low-grade angiosarcoma first described in 1969 by Maria Dabska. Approximately 30 cases of varying presentations have been reported since its initial description. METHODS We describe a case of a 23-year-old woman presenting with a massive recurrent left flank hemangioendothelioma, at final resection diagnosed to be an endovascular papillary angioendotheliom...

The goal of surgical treatment for gastrointestinal stromal tumor (GIST) is the complete resection of the tumor. A 62-year-old male had a clearly distinguishable mass having a smooth surface at the right side of the lower esophagus by computed tomography. Thoracoscopic resection of the tumor was performed. Immunohistochemical analysis showed that the tumor was positive for c-KIT and CD34 withou...

intra-abdominal desmoplastic small round cell tumor is a rare entity with a few reports worldwide. this tumor commonly occurs in children and adolescent and occurrence in adult age group is very rare. here, we describe an adult male with symptoms of intestinal obstruction due to abdominal mass, located in splenic flexure. after resection, the diagnosis of intra-abdominal desmoplastic small roun...

Chondrosarcoma is a malignant tumor originating in cartilaginous cells. And there are only few reports of the case of chondrosarcoma in temporomandibular joint. We discuss a case of chondrosarcoma in temporomandibular joint in a 28-year-old man. Tumor was in contact with the dura, but en bloc resection was performed. After surgical resection of the tumor, face defect was reconstructed by rectus...

OBJECTIVE The aim of this study was to demonstrate the usefulness of a mobile, intraoperative 0.15-T magnetic resonance imaging (MRI) scanner in glioma surgery. METHODS We analyzed our prospectively collected database of patients with glial tumors who underwent tumor resection with the use of an intraoperative ultra low-field MRI scanner (PoleStar N-20; Odin Medical Technologies, Yokneam, Isr...

Introduction: Parapharyngeal space (PPS) tumors account for 0.5% of the head and neck neoplasms. Based on the evidence, 80% of these tumors are of a benign nature. Surgical excision is the treatment of choice for this condition. The present study was conducted to propose transoral resection as an efficient way to excise the benign well-defined tumors of the PPS.   Materials and Methods: Thi...

Introduction: Teratomas are neoplastic tumors derived from totipotent germ cells containing a wide assortment of tissues originating from all three germ cell layers. Teratomas can be mature or immature depending on the presence of immature tissues; typically neuroepithelial tissue. Immature teratomas can be oncologically benign or malignant, and can be divided into three grades with increasingl...
