BACKGROUND Odontogenic fibromyxoma is an uncommon benign tumor arising from the maxillofacial bones. Fibromyxomas are rare in children under 10 years of age. Although this tumor is reported most frequently in the mandible for the general population, it has rarely been reported in the mandible in children <10 years of age. METHODS We reviewed the 39 reported cases of odontogenic fibromyxoma in...

Chondromyxoid fibroma is an unusual benign tumor of cartilaginous tissues that may be confused with other some malign tumors. It is rarely seen in the skull. A 45-year-old female was admitted with painless bony swelling in the forehead. Computerized tomography demonstrated a well-defined expansive lesion with a sclerotic margin measuring approximately 3 cm in diameter in the right frontal bone....

Desmoplastic fibroma of bone is a rare myofibroblastic tumor, locally aggressive, benign lesion that histologically resembles a desmoid tumor of the soft-tissue. It was initially described in 1958 by Jaffe, who separated it as a distinct entity from other intraosseous fibrous tumors. This tumor constitutes <1% of bone tumors and about 0.3% of all benign osseous tumors and it usually involves th...

Introduction: Few studies on benign soft tissue tumors of oral cavity have been conducted in an Iranian population. The purpose of this study was to evaluate the prevalence of the benign soft tissue tumors of the oral cavity in three central pathology centers of Rasht, Iran. Materials and Methods: In this retrospective study, all benign soft tissue tumors of the oral cavity, were retrieved fro...

Introduction/Objectives. Bone and soft tissue infections might mimic bone tumors. Therefore, differential diagnosis is important to prevent errors in treatment. This report aims present the data of patients with indistinct clinical radiological findings mimicking benign malignant tumors, which were later diagnosed as inflammatory infections. Methods. A retrospective chart review clinical, micro...

Giant cell reparative granulomas (GCRG) are non-neoplastic rapidly expanding and locally destructive lesions typical of facial skeleton bones. Jaffé first described these lesions in 1953, designating benign lesions of the jaw that were histologically different from true giant cell tumors of long bones. Mandibular GCRG area rare lesions, comprising less than 7% of all benign bone lesions of the ...

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...
