Orofacial pain can be caused by intracranial disorders or can be musculoskeletal, vascular, internal derangemental, and neurologic in origin. The neurologic pain is derived from structural and functional disorders of nerve, and the trigeminal neuralgia is the typical manifestation. Trigeminal neuralgia is known from centuries ago, and is one of the most common pains in human. We present our experience with three patients who have trigeminal neuralgia. The first case is a 50-year-old female who had no specific evidence radiographically. Second is a 50-year-old male with microvascular compression on right trigeminal nerve. The third case is a 60-year-old female who had a neoplasm in cerebellopontine angle with associated mass effect.

Schwannoma named neurinoma, peripheral glioma, perineural fibriblastoma and Neurilemmoma is a ectodermal benign neoplasm which originates from schwann cell or neuro axons. It usually develops in peripheral systems of sensory nerves of gastrointestinal tract, oral cavity, and bone. It occurs more frequently in soft tissue than hard tissue, and is extremely rare in intraoral area. We report a case of Schwannoma that showed large mass on buccal cheek with Rt. midfacial swelling, pain, tenderness to palpation and involvement with maxillary branch of trigeminal nerve. We present this case and review the literature.

Mucoepidermoid carcinoma (MEC) is the most common type of malignant neoplasm in the minor salivary gland. The hard palate is a frequently involved site of MEC. The treatment of low-grade MEC on the hard palate is wide local resection with a tumor-free margin. In the present case, the maxillary defect was reconstructed using a buccal fat pad (BFP) flap, followed by application of 4-hexylresorcinol (4HR) ointment for 2 weeks. The grafted BFP successfully covered the tumor resection defect without tension and demonstrated complete re-epithelialization without any complications.

Adenoid cystic carcinoma is malignant neoplasm belonging to a group of tumors of salivary gland origin. It is an aggressive tumor characterized by slow growth and incidious destruction of surrounding tissues. Perineural invasion is a prominent feature. Spread to regional lymph node is rare, other than by direct extension. Distant metastasis are more common. We experienced a 65-year old female with adenoid cystic carcinoma of minor salivary gland in retromolar pad.

The calcifying epithelial odontogenic tumor is a rare benign odontogenic neoplasm which was first described by Pindborg in 1955 and accounts for less than 1％ of all odontogenic tumors. The tumor occurs primarily in the molar-premolar region of the mandible, and 52％ of cases are associated with an unerupted tooth. The clinical feature is most commonly a slow-growing painless swelling. The tumor may show considerable radiographic variation and usually characteristic histopathologic features. In this study, we report a case of the calcifying epithelial odontogenic tumor on the left mandibular body and ramus area in a 28-year-old male with a brief review of the concerned literatures.

Calcifying cystic odontogenic tumor (CCOT) is an uncommon benign cystic neoplasm of the jaw that develops from the odontogenic epithelium. Invasion into the maxillary sinus by a CCOT is not a typical, and the recurrence of the cystic variant of CCOT in the posterior maxilla is rare. This report describes a recurrent CCOT occupying most of the maxillary sinus of a 24-year-old male patient. As a treatment, marsupialization was carried out as a means of decompression, and the involved teeth were all endodontically treated. Afterward, surgical enucleation was performed. The size of the lesion continued to shrink after marsupialization, and the maxillary sinus restored its volume. This patient has been followed-up for 3 years after the surgery, and there have not been any signs of recurrence.

Metastases to the jawbones are found predominantly in the mandible and are rare in relation to the overall spectrum of oral malignancy. Analysis of the literature shows that the most frequent primary sites are the breast, lung, kidney, thyroid, and prostate. Adenocarcinoma of the mandible, whether primary or metastatic, are usually difficult to diagnose clinically. We report a case illustrating the clinical, radiographic, and histologic findings of a metastatic lung adenocarcinoma of the anterior mandible in a 58-year-old male.

The odontogenic myxoma is an infiltrative benign tumor of bone that occurs almost exclusively in the jaw bones and comprises 3% to 6% of odontogenic tumors. This neoplasm is thought to arise from the primitive mesenchymal structures of a developing tooth, including the dental follicle, dental papilla, or periodontal ligament. Radiographically the odontogenic myxoma may produce several patterns: unicystic, multilocular, pericoronal, and radiolucent-radiopaque, making the differential diagnosis difficult. In this report, two cases of the odontogenic myxoma in the jaw bones are presented. The first case involved only the mandible, while the second case involved the maxilla. Both cases presented extensive multilocular radiolucencies characteristic of odontogenic myxoma.

Extranodal NK/T-cell lymphoma (NTCL), nasal type is rare and highly fatal malignant neoplasm. Early diagnosis and establishing treatment plan are very difficult. Furthermore, NTCL in the mandible is an extremely rare condition. The clinical significance of presented case is the very rare location of NTCL. To the best of author's knowledge, this is the first reported case of NTCL of the mandible in the literature.

This case was diagnosed as multiple cementoosseous dysplasia on the basis of clinical & radiological features but was diagnosed as ossifying fibroma on the basis of histopathological feature. The histopathologic features of the multiple cementoosseous dysplasia and cementoossifying fibroma have common features of cementum, fibrous network and bone. Multiple cementoosseous dysplasia is reactive lesion and shows restricted lesion size, occurred on anterior and posterior tooth of the mandible and needs no treatement except periodic follow up. But Cementoossifying fibroma is the true neoplasm and grows continuously and needs surgical removal. The final diagnosis of the multiple cementoosseous dysplasia requires good correlation of the clinical, histopathological, and radiological features.
