Odontomas have been extensively reported in the dental literature, and the term refers to tumors of odontogenic origin. Though the exact etiology is still unknown, the postulated causes include: local trauma, infection, inheritance and genetic mutation. The majority of the lesions are asymptomatic; however, may be accompanied with pain and swelling as secondary complaints in some cases. Here, we report a case of a compound odontome in a 14 year old patient.

Adenoid cystic carcinoma (ACC) of salivary glands is a slow-growing malignant tumor, characterized by wide local infiltration, perineural spread, a propensity to local recurrence and late distant metastasis. Although ACC is the second most common malignant salivary gland neoplasm and constitutes approximately one-third of all salivary gland malignancies, it is relatively rare in parotid gland. Here, we present a case report of a cribriform type of ACC involving parotid salivary gland in a 66-year-old female.

Among CD44s and its variant isoforms,v5, v6, in this study, variant isoform v6 may serve as a marker in detecting high-risk leukoplakias.

Purpose: The Sturge-Weber syndrome (SWS) is a rare congenital disorder that occurs sporadically and features lesions of both skin and nervous system. We report a case of 7 year-old girl with Sturge-Weber syndrome and discuss its clinicopathological features, differential diagnosis and also emphasize the importance of its diagnosis in the clinical oral practice.Case Description: The classic pathognomonic manifestations include angioma of the leptomeninges extending to cerebral cortex with ipsilateral angiomatous lesions, unilateral facial nevus affecting a division of trigeminal nerve, hemiparesis, intracranial calcification, mental retardation and refractory epilepsy. The most apparent indication of SWS is a facial birthmark or "Port Wine Stain" present at birth and typically involving at least one upper eyelid and the forehead. Management of a patient with Sturge-Weber Syndrome may be challenging due to risk of hemorrhage.Conclusion: The dentists should focus on comprehensive therapy, starting with behavior management and stress on preventive measures.

Spindle cell soft tissue neoplasms are rarely reported in the oral cavity and account for less than 1% of all tumors. Spindle cell carcinoma (SpCC) synonymously called sarcomatoid tumor occurs mainly in the upper aerodigestive tract. This peculiar malignant neoplasm predominantly affects males in 6-7 th decades of life. SpCC is potentially aggressive with a high incidence of metastases. Its precise and early diagnosis is the key to good prognosis. We report a case of SpCC in a 50-year-old male patient with special reference to histogenesis of this entity. SpCC is an aggressive variant of squamous cell carcinoma which needs to be identified and differentiated from the other spindle cell tumors for proper treatment.

Fibrous dysplasia is a benign fibro-osseous lesion of the bone that commonly affects the jaws with a higher prevalence in the maxilla than the mandible. It is a lesion of unknown etiology, uncertain pathogenesis, and diverse histopathology. Fibrous dysplasia can involve multiple bones (polyostotic) or a single bone (monostotic). It represents about 2 to 5% of all bone tumors and over 7% of all benign tumours. In this article we report the case of a 20 year old patient with monostotic fibrous dysplasia involving the left maxilla.
