Intraosseous vascular lesions are rare conditions. They are most commonly seen in the vertebral column and skull; nevertheless, the mandible is a quite rare location. In this report, we present a case of intraosseous cavernous hemangioma in the mandible and discuss the clinical and radiological features. A 28-year-old male patient attended to our clinic with a complaint of painless swelling of ...

Intraosseous schwannoma is a rare benign neoplasm arising from Schwann cells of the nerve sheath and involving the substance of bone. Intraosseous schwannomas account for less than 0.2 % of primary bone tumors. The most common site of occurrence is the mandible, a characteristic traditionally attributed to the long intraosseous path of the inferior alveolar nerve. Here we report a case of intra...

BACKGROUND Mucoepidermoid carcinoma arises from major or minor salivary glands, making up 10% of salivary gland tumors. Intraosseous mucoepidermoid carcinomas are rare, and make up only 2% to 3% of all mucoepidermoid carcinomas. The t(11;19) and its CRTC1-MAML2 fusion gene transcript have been identified in mucoepidermoid carcinoma and are associated with a subset of mucoepidermoid carcinomas. ...

BACKGROUND Hibernoma is a rare benign tumor of adults that is composed of multivacuolated adipocytes resembling brown fat cells. Hibernoma typically occurs in soft tissue, and intraosseous examples are very rare. Intraosseous hibernomas can radiologically mimic metastatic carcinoma and other tumorous conditions. METHODS To collect the intraosseous hibernomas, we searched the pathologic databa...

We report on a case of intraosseous lipoma in the talus of a 61-year-old man. Roentgenographic, computed tomographic (CT), magnetic resonance (MR), and histologic features of the case are presented. To our knowledge, this is the first reported case of intraosseous lipoma occurring in the talus. SICOT Online Report E029 Accepted April 8th, 2003 2 Introduction Intraosseous lipoma is the rarest be...

Lipoma is a very common tumor developed in soft tissue like subepithelium, however, intraosseous lipoma developed inside the bone is a quite rare tumor showing less prevalence than 0.1% or 2.5% among primary tumors developed inside the bones. Intraosseous lipoma has been reported to occur usually in metaphyseal or epiphyseal regions of long bones such as femur, tibia, fibula, and calcaneus, but...

intraosseous squamous cell carcinoma is a rare type of squamous cell carcinoma that requires accurate and early diagnose which is important due to its invasive feature. this article presents a rare case report on intraosseous carcinoma in a 33-year-old patient. the case was a 33-year-old man who was referred to oral disease department of babol college of dentistry complaining of chin pain. in t...

Many investigators have considered that local vascular changes may be important in the etiology and pathogenesis of degenerative arthritis, but opinions differ as to the nature of these changes. Several authors have suggested that osteoarthritis is accompanied or preceded by a state of ischaemia of subchondral and juxtachondral bone (Wollenberg 1909; Goldhaft, Wright and Pemberton 1930; Phemist...

OBJECTIVE Our objectives were to ascertain whether CO2 can be used as a contrast agent in venography during percutaneous vertebroplasty and to evaluate whether it might be capable of replacing nonionic iodinated contrast agents. CONCLUSION Intraosseous venography with CO2 contrast agent was slightly inferior to iodine venography in terms of its ability to visualize the vertebral bodies and pe...

BACKGROUND Since bone marrow receives innervation from A-delta and C-fibers and since an increase in intramedullary pressure in bone marrow may induce acute pain in orthopedic patients during surgery and chronic pain in patients with bone marrow edema, skeletal pain may partly originate from bone marrow. Intraosseous lesions, such as osteomyelitis and bone cancer, are also known to produce cuta...
