BACKGROUND Clear cell odontogenic carcinoma (CCOC) is a rare intraosseous carcinoma of the jaw; only 81 cases have been reported in the English literatures. CASE PRESENTATION We reported an additional case and reviewed the existing literature. A 70-year-old woman presented with a large painful radiolucent mandibular lesion from the right canine to the left angle area through the midline. No m...

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...

Fibrosarcoma is a malignant mesenchymal neoplasm of fibroblasts that rarely affects the oral cavity and can cause local recurrences or metastasis. Fibrosarcomas account for 15% of all soft tissue sarcomas, which represent only 1% of all malignant tumors of the head and neck region. The clinical behavior of the fibrosarcoma is characterized by a high local recurrence rate, and low incidence of l...

myofibroma is an uncommon benign mesenchymal neoplasm. solitary myofibroma is common in soft tissues of head and neck, but rare in the jaw bones. only a few sporadic cases of solitary myofibroma of mandible have been described. the aim of the present study was to present a clinical case of a patient with a myofibroma in mandible bone and its management. differentiating this lesion from other be...

Intraosseous ganglia are benign cystic lesions located in the subchondral bone. Intraosseous ganglion cysts of the ankle are relatively uncommon. We present a case of recurrent intraosseous ganglion in the ankle of a 41-year-old female who had recurrence after initial surgery. She was treated effectively by curettage and autogenous cancellous bone grafting. At the final follow-up, satisfactory ...

Abstract Introduction Primary intraosseous carcinoma (PIOC) of the jaw is an incredibly rare lesion with approximately 200 cases reported in literature. PIOC are mostly asymptomatic incidental radiographic findings and present as poorly-defined, non-corticated radiolucencies often root resorption cortical perforation. Prognosis considered poor best predicted by histological grade. Case report A...

BACKGROUND Fibrinogen concentrate is increasingly considered as a hemostatic agent for trauma patients experiencing bleeding. Placing a venous access is sometimes challenging during severe hemorrhage. Intraosseous access may be considered instead. Studies of intraosseous infusion of coagulation factor concentrates are limited. We investigated in vivo recovery following intraosseous administrati...

OBJECTIVE To compare a computerized intraosseous anesthesia system with the conventional oral anesthesia techniques, and analyze the latency and duration of the anesthetic effect and patient preference. DESIGN A simple-blind prospective study was made between March 2007 and May 2008. Each patient was subjected to two anesthetic techniques: conventional and intraosseous using the Quicksleeper®...

Squamous cell carcinoma (SCC) derived from keratocystic odontogenic tumor is an extremely rare tumor that is limited to the jaws. Most intraosseous carcinomas originate from the epithelial lining of odontogenic cysts, so they are called odontogenic carcinomas. They occur more frequently in men and the mean age of patients is 57 years. The following report describes an extremely rare case of an ...

Benign primary intraosseous meningioma presenting with osteolytic skull lesion and soft-tissue component is rare. CT and MR imaging of a patient with frontoparietal scalp swelling showed an osteolytic intracalvarial lesion with an extradural soft-tissue component. Following wide surgical resection, the histological examination revealed an intraosseous chordoid meningioma. The clinical and radio...
