Mesenchymal chondrosarcoma (MC) is an uncommon tumor with an aggressive behaviour. We present two cases of MC. The first one is a unique case of MC of the maxilla metastasized from the clavicle. The second describes MC in the mandible with extensive involvement of the condyle. A 31-year-old male and a 22-year-old male presented to Saveetha Dental College, with a 2-month history of progressiv...

  Peripheral calcifying cystic odontogenic tumor (PCCOT) is a rare odontogenic lesion, which represents about 1% of jaw cysts. Here we report clinicopathologic, radiographic and CT scan images of a new case of recurrent large PCCOT located in mandibular gingiva in a 77-year-old male with history of a nodular mass in the same area, which had been completely excised 3 years ago. In reviewing the...

Osteoma is a dense bony proliferation of otherwise normal membranous bone. This tumor is essentially restricted to the craniofacial skeleton and is rarely diagnosed in other bones. The mandible and the paranasal sinuses are the most common sites, while the involvement of the coronoid process has been reported in only 6 cases so far. This report demonstrated a case of osteoma occurring at the ma...

background and aims. postoperative pain control is extremely important for both patients and surgeons; in this context, long-acting local anesthesia can play an important role after open reduction of maxillofacial fractures. the purpose of this study was to evaluate the effect of bilateral mental nerve block with bupivacaine on postoperative pain control in mandibular symphyseal fractures. mate...

Pure trigeminal motor neuropathy is characterized by trigeminal motor weakness without signs of trigeminal sensory or other cranial nerve involvement. We describe a 63-year-old woman with progressive weakness and atrophy of the left masticatory muscles. She had no sensory disturbance. The diagnosis of pure trigeminal motor neuropathy was made on the basis of clinical and electrophysiologic stud...

Caffey's disease, also known as Infantile Cortical Hyperostosis, is a rare, self-limited, benign, inflammatory gene-related disorder of infants that causes bone changes, soft tissue swelling, and irritability. The mandible (75%), clavicles, and ulnae are the bones most frequently involved, others being long bones, lateral ribs, ilia with skull being the rarest. However, we report a case of a 5-...

Hobnail hemangioma is a rare benign vascular tumor. It usually develops in young adults as a single, small, well-circumscribed, angiomatous/pigmented, and flat or exophytic lesion and has a distinctive biphasic histopathologic appearance. Lesions commonly affect the trunk and lower and upper extremities, although head and neck involvement has also been described. Until now, only 3 intraoral cas...

OBJECTIVES This study used cone-beam computed tomography (CBCT) images to categorize the relationships between the mandibular canal and the roots and investigated the prevalence of nerve damage. MATERIALS AND METHODS Through CBCT images, contact and three-dimensional positional relationships between the roots of the mandibular third molar and the mandibular canal were investigated. With this ...

Epithelioid hemangioendothelioma is a rare vascular neoplasm which exhibits the potential for malignancy and recurrence as well as the ability to metastasize. Although numerous sites of involvement are possible, these tumors most commonly arise in soft tissues, lung, liver, bone, and lymph nodes. In this report, we describe a case of oral epithelioid hemangioendothelioma in a child. This tumor ...
