Odontogenic myxomas are benign but locally aggressive neoplasms found almost exclusively in the jaws and arise only occasionally in other bones. We present a rare case of odontogenic myxoma occurring in the mandible of a 19-year-old male patient with a brief review of clinical and radiological features, and diagnostic and operative dilemmas in managing the same.

econstruction of the mandible presents unique challenges to the head and neck surgeon. Although mandibular defects can result from trauma, infection, congenital deformities, or osteonecrosis, it most commonly occurs following ablative surgery for the treatment of benign or malignant neoplasms. Primary intrabony mandibular carcinoma is rare; therefore, the involvement of the lower jaw is usually...

BACKGROUND Osteosarcomas are very rare malignant mesenchymal neoplasms affecting jaw bones. Only few studies are reported about this lesion in this particular region. OBJECTIVE We wanted to assess the demography and tumor behaviour and histopathological pattern, retrospectively in the available cases. METHODS A retrospective analysis of hospital records for 20 years was carried out. Clinica...

Context: The essential role of a general dental practitioner is recognizing the nature of the oral cavity lesions. Periapical lesions, which are observed in radiographs of patients, may have odontogenic or nonodontogenic origins. This review aimed to study differential diagnosis of common and important periapical lesions. Evidence Acquisition: English-language literature were searched by manual...

Gorlin-Goltz syndrome is an uncommon disorder transmitted through autosomal dominant inheritance. This syndrome is characterized by multiple odontogenic keratocysts, along with congenital skeletal anomalies and basal cell carcinomas. A 16-year-old girl was admitted with a complaint of swelling on the lower jaw. She had multiple basal cell nevi on both hands. Multiple lytic bone lesions on radio...

Osteosarcoma (OS) is one of the most common primary malignant bone neoplasms, which predominantly occurs in the long bones and rarely in the maxillofacial area. We present a rare case of maxillary OS early diagnosed in a 17-year-old girl through clinical, radiological and histological examination. The treatment involved surgical resection of the tumor followed by radiation therapy and chemother...

Osteoid osteomas are benign skeletal neoplasms that are commonly encountered in the bones of the lower extremities, but are exceedingly rare in jaw bones with a prevalence of less than 1%. This unique clinical entity is usually seen in younger individuals, with nocturnal pain and swelling as its characteristic clinical manifestations. The size of the lesion is rarely found to be more than 2 cm....

Odontogenic myxomas (OMs) are benign mesenchymal locally aggressive neoplasms of the jaw bone. Although OMs predominantly involve the mandible, maxillary tumors are usually more aggressive than mandibular tumors. The present study describes the case of a 37-year-old male with a large odontogenic myxoma of the bilateral maxillae, which caused a defect in the right skull base bone. The tumor was ...

Introduction: The odontogenic myxoma is generally considered to be a rare neoplasm unique to the jaws. In the international histological classification of odontogenic tumors, odontogenic myxoma (OM) is defined as a benign odontogenic tumor of mesenchymal origin that is locally invasive and consists of rounded and angular cells lying in abundant mucoid stroma. Since these neoplasms are rare in t...

Previously1), we have determined the various jaw movements of rabbits that can be evoked by electrical stimulation of the cortical jaw motor region. Jaw movement induced by stimulation of the neocortical jaw motor region was predominant in a jaw opening direction whereas that following stimulation of the amygdala was predominant in a jaw closing direction. Additionally, these two brain regions ...
