To date, there are still very few reports on benign-tumor cases based on East Asian skeletal series, even though other regions and continents have been well represented. In our study on the Joseon Human Skeletal Series, we identified benign bone tumors in two skeletons (cases Nos. 75 and 96). Our radiological analyses showed both cases to be homogeneous sclerotic bone masses aligned with the cr...

Chondromyxoid fibroma (CMF) is a rare benign cartilaginous tumor with a predilection for the bones of lower extremities and about one fourth of the tumors involve the foot. Radiologically, an eccentric lytic lesion with well-defined margins is seen in the metaphysis of the bone. We hereby, report an 18 yr old young male who presented to Orthopedic Outpatient Department, JN Medical College, Alig...

OBJECTIVE To describe the clinical manifestations and types of, and our surgical experience with, neoplasms in the region of the temporomandibular joint (TMJ) in pediatric patients. MATERIALS AND METHODS From September 1997 to December 2013, a total of 18 patients with neoplasms in the region of the TMJ were treated at our department. They all underwent open surgeries. The clinical manifestat...

Meningeal hemangiopericytomas are rare vascular tumors that have a propensity for recurrence and metastasis. Intracranial hemangiopericytomas are rare vascular tumors. They account for 0.5% of primary central nervous system tumors and 2% of meningiomas. Unlike usual benign meningiomas, which rarely metastasize extracranially, meningeal hemangiopericytoma has a high rate of local recurrence and ...

Due to excellent soft tissue contrast and multiplanar imaging capability, MRI is assuming a major role in recognition, staging, and treatment planning of soft tissue and bone tumors. Direct sagittal, coronal, and axial images permit assessment of intraosseous and extraosseous extension of tumors and their relationship to the joints and neurovascular structures, and detection of "skip" lesions. ...

Giant-cell tumor of the bone is a benign tumor, but with high local aggressiveness, even with risk of distant metastasis. From an epidemiological standpoint, giant-cell tumor of the bone accounts for 4-5% of primary bone tumors and ~20% of benign bone tumors; commonly affects adults between 20-40 years, slightly more common in females. We present the case of a 57-year-old woman, without signifi...

-Abstract=We report here 6 cases with classical forms of nonossifying fibroma (NOF) and 1 case of fibrous cortical defect (FCD) which occurred in the metaphysis of the long bones of children along with 2 cases of fibrous histiocytoma (FH) which occurred in the veretebra and femur neck of adults. Their clinical data, radiographs, histopathology, and ultrasturctural features are described. Throug...

 Background: Ovarian masses represent a range of pathology from benign cyst to highly aggressive malignant tumors. It has been estimated that gynecologic malignancy account for approximately 2% of all types of cancer in children, 60-70% of these lesions arise in the ovary.  Methods: All ovarian masses which were resected or biopsied in Mofid Children's Hospital from 2002 to 2012 were reviewe...
