Introduction. We present a case of intraosseous foreign body penetration due to knife attack and its emergency service management. Case. Seventeen-year-old patient was admitted to the emergency department with a knife cut over the right knee. In the local wound exploration during the extension position of the knee, deep tissue penetration was not observed. Therefore, the patient was discharged ...

Squamous cell carcinoma (SCC) arising within the lining of an odontogenic keratocyst (OKC) is a rare occurrence. Although potentially locally destructive, OKC is a benign odontogenic process that typically presents with clinical and radiographic features characteristic of a benign intraosseous neoplasm. We present the clinical and radiographic features of a maxillary mass that demonstrated SCC ...

A case of bilateral intraosseous tumor of the calcaneus with different MRI imaging is presented. On the left, radiological findings suggest intraosseous lipoma, but on the right-sided lesion, imaging studies were not convincing. The microscopic report showed foreign body granulomatous reaction, a rare clinical pathological discordant.

Centrally occurring salivary gland tumors are rare. Because of a considerable overlap between the clinical and histopathological features, this group of tumors often produces a diagnostic difficulty to the clinicians and oral pathologists. Acinic cell carcinoma (ACC) is an unusual, low-grade, malignant salivary gland tumor that represents approximately 2% of the salivary gland tumors with almos...

Primary intraosseous carcinoma (PIOC) is a rare malignant neoplasm of the jaws which is locally aggressive with quite poor prognosis. Overall and disease free survival is poor with almost 50% patients failing within first 2 years of follow up and reason can be attributed to the delayed diagnosis. But knowledge of the clinical, radiographic and histopathologic features of PIOC allows accurate an...

BACKGROUND Primary intraosseous salivary-type adenocarcinomas are rare neoplasms of uncertain histogenesis. The prevailing theories suggest origin from heterotopic salivary glands, odontogenic rests, or cystic epithelium. METHODS A case of central adenoid cystic carcinoma is reported in a 53-year-old woman who presented with a painless swelling in the anterior segment of her lower jaw. Radiog...

Benign primary intraosseous meningioma presented as unilateral proptosis is a rare case in our settings. The reported occurrence is 1%-2% of all meningiomas. This type of tumour has numerous nomenclature that represents its location outside the dural component, such as ectopic, extracranial, calvarial and extraneuraxial. Although it is a benign entity, the tumour can cause significant disfigure...

Primary intraosseous cavernous hemangiomas (PICHs) are benign vascular tumors that may involve any part of the body. PICH occurs more frequently in the spine and less commonly in skull. The earliest description in the English literature was in 1845 by Toynbee, who reported a vascular tumor arising in the confines of the parietal bone. Skull PICHs do not always have typical radiologic features a...

An 8-year-old boy presented with an osteolytic lesion at the fourth metatarsal of the right foot. He received a surgical excision. Microscopically, the tumor was composed of lobules of capillary sized vascular channels with occasional dilated crescent-shaped openings at the periphery. Intraosseous hemangioma accounts for approximately 1% of all primary bone tumors. Furthermore, it is especially...
