BACKGROUND This study was conducted to examine the clinical usefulness and efficacy of endoscopic curettage on benign bone tumor. METHODS Thirty-two patients (20 men and 12 women) with benign bone tumor were included in the study. The patients were aged between five and 76 years; the mean follow-up period was 27.05 months (range, 9.6 to 39.9 months). The primary sites include simple bone cyst...

Aneurysmal bone cyst (ABC) is a benign, locally aggressive tumor of long bone and vertebral bodies. Soft tissue aneurysmal bone cyst (STABC) is an extremely rare entity that has same morphology as their osseous counterparts. The aim of this study is to keep in mind STABC in differential diagnosis of some benign and malignant tumors. A 68-year-old male presented with a swelling on his right shou...

We present a case of spinal tumor, with fibrohistiocytoma combined with aneurysmal bone cyst (ABC) at the pedicle and transverse process of T7 in a 63-year-old female. ABC is a rare skeletal tumor and spinal ABC is extremely rare. Fibrohistiocytoma is a type of primary benign bone tumor. ABC is also a rare bone tumor that most often occurs in the pelvis. The combined lesion of two primary bone ...

osteoid osteoma is a benign bone tumor that rarely involves joints. although there are several reports of arthroscopic osteoid osteoma excisions, to our knowledge, there are no reports of this type of treatment for osteoid osteoma in carpal bones. we report two cases of arthroscopic (a person who had a pain in the left wrist and the other one with carpal tunnel syndrome) with excision of osteoi...

background: understanding the differences in genetics of malignancies is crucial for therapeutic decisions. this systematic review was conducted to evaluate the current evidence on genetics of bone tumors in the context of pediatric cancer. material and methods: we performed a systematic review of the literature published on genetics of pediatrics bone tumors, using pubmed, google scholar, scie...

introduction: a keratocystic odontogenic tumor is a benign intra-bone mass originating from dental lamina or its residue. it represents 2–11% of jaw cysts, and has a slow but aggressive growth. the evaluation of molecular characteristics, immunohistochemistry, and genetic expression currently have no established classification regarding the evolution and pathophysiologic pattern of these lesion...

osteosarcoma (os) is a malignant mesenchymal tumor, which rarely occurs in the maxilla. although variable histologic and radiographic features of os have been reported previously, in the majority of the cases painful swelling of the jaw is mentioned as the first clinical presentation. furthermore, early diagnosis and wide surgical resection of the tumor are the most important determinant factor...

OBJECTIVE To analyze different fluid-fluid level features between benign and malignant bone tumors on magnetic resonance imaging (MRI). MATERIALS AND METHODS This study was approved by the hospital ethics committee. We retrospectively analyzed 47 patients diagnosed with benign (n = 29) or malignant (n = 18) bone tumors demonstrated by biopsy/surgical resection and who showed the intratumoral ...

Chondromyxoid fibroma (CMF) is a rare, benign cartilaginous tumor, comprising less than 1% of primary bone tumors, and usually occurs in the metaphysis of a long tubular bone around the knee. We report a rare case of CMF of the rib. The patient was a 25-year-old man who visited the hospital for left upper back pain. Roentgenography revealed an 8-cm mass in the left upper lung field; computed to...
