Schwannoma(neurilemmoma) is a benign tumor originates from Schwann cells. Ancient (degenerated) schwannoma is a long-standing schwannoma with degenerative changes. Head and neck region is one of the most common sites for nerve sheath tumors but intraosseous schwannoma is rare. The mandible is the most common site of occurrence for this lesion. We report a rare case of intraosseous ancient sc...

The etiologies of Keinböck's disease and intraosseous ganglion remain unknown. Both entities are rare and the coexistence of these two pathologies in the same patient and hand is even less frequent. We report the case of a 40-year-old man with a longstanding history of martial arts practice (karate) who developed an avascular necrosis of the lunate concomitant with a giant intraosseous ganglion...

Primary de novo intraosseous carcinoma (PIOC) is a rare and unique neoplastic lesion commonly occurring in the jaws. It is locally aggressive with very poor prognosis. Hereby we are presenting a case of proliferative growth from the non-healing extraction socket in a 45 year old female patient with eroded coronoid process and ramus of the mandible radiographically. (Lakshman AR, Kanneppady SK: ...

Intrasynovial sepsis in horses results in severe lameness and can potentially be careerand/or life threatening. In foals, infectious arthritis secondary to the hematogenous spread of bacteria is the most common form of intrasynovial infections encountered, whereas traumatically induced septic tenosynovitis and infectious arthritis seem to be more common in adults. Successfully treating an infec...

This is the third part of a review of the clinicopathologic features of intraosseous carcinoma of the jaws (IOCJ). In parts 1 and 2, we discussed metastatic and salivary-type and odontogenic carcinomas, respectively. This part deals with primary intraosseous squamous cell carcinoma. Again, based on a critical approach, we emphasize histopathologic features, diagnostic difficulties, discuss hist...

A 29-year-old healthy patient was submitted for exploration of intraosseous, unicystic lesions of the mandibular angle distal to the wisdom tooth of both sides. Histological investigation of the enucleated cystic lesions revealed bilaterally developed lymphoepithelial cysts (LEC). Healing was uneventful and re-ossification of the bone complete. LEC are rarely diagnosed in oral tissues and usual...

Schwannoma (neurilemmoma) is a benign neoplasm originated from the neural sheath and occurring most frequently in the head and neck. Intraosseous schwannomas are rare. The mandible is the most common site of occurrence for these lesions. This article reports the case of an intraosseous schwannoma located in the mandibular symphysis of an 11-year-old boy. The lesion was surgically removed and no...

Intraosseous ameloblastoma is the most common and simple type of ameloblastoma prevalent among odontogenic tumors. Clinico-radiographically intraosseous ameloblastoma presents as slow, painless swelling or expansion of the jaws and described as multilocular expansile radiolucency that occurs most frequently in mandibular molar/ramus area. This article describes a case of follicular ameloblastom...

The intraosseous pressure in the femur and tibia near the knee and in the internal saphenous vein at knee level was measured in fifty-three patients with suspected knee lesions. There were four groups: with and without degenerative osteoarthritis and with and without aching rest pain of the knee region. Low intraosseous pressures were found in patients with neither osteoarthritis nor rest pain,...

Two infants on the neonatal unit aged 143 days and 47 days with difficult venous access were successfully resuscitated from episodes of coliapse using the intraosseous route. (Arch Dis Child 1993;68:324-325) Intraosseous resuscitation of babies and infants is taught to residents in North America in the paediatric advanced life support course.1 No such formal training is widely available in Grea...
