Objective: Studies on odontogenic tumors published from many parts of the world show a distinct geographic variation; however, there is little information available in the English-language literature on the relative frequency of odontogenic tumors in India. This retrospective study was designed to determine the relative frequency of odontogenic tumors in an Indian population and compare them with various reports from other parts of the world. The controversy still exists regarding the nature of odontogenic keratocyst or tumor, so it has not been included in this study. Results: A total of 60 cases of odontogenic tumors were reported in this period. The most frequent histological type was ameloblastoma (66.67%), followed by odontome (20%), adenomatoid odontogenic tumor (10%). In general, the odontogenic tumors showed a predilection for the mandible and the posterior regions of the jaws. Ameloblastomas occurred with a marked predilection for the mandible, while adenomatoid odontogenic tumor showed predilection for the maxilla, anterior regions of the jaws, and young females. Conclusion: Odontogenic tumors show a definite geographic variation. In our study, ameloblastomas were the most frequent odontogenic tumors, with distinct anatomic predilections.
Cysticercosis is a parasitic infestation caused by the larval stage of Taenia solium. It is common in regions where humans and animals live in close contact, with poor sanitation, and due to consumption of infected meat. The tissues affected are the subcutaneous layers, brain, muscle, heart, liver, lungs, and peritoneum. Oral manifestations are very rare. The most common intra-oral site is the tongue. Here, we present a case in a who sought treatment for an asymptomatic nodule in the upper lip. A gross specimen revealed a cystic cavity containing clear watery fluid and white membranous flecks. The histopathology showed features of cysticercosis.
Treacher Collins syndrome (TCS) is a rare autosomal dominant disorder of craniofacial development. It is a congenital malformation of first and second branchial arch which may affect the size and shape of the ears, eyelids, cheek bones, and jaws. The extent of facial deformity varies from one affected individual to another. A case of 20-year-old boy having TCS is briefly described in this article.
Ameloblastoma, a benign epithelial odontogenic tumor, is locally aggressive. This tumor comprises about 1% of tumors and cysts arising in the jaws. It appears most commonly in the third to fifth decades and with equal frequency between sexes. Ameloblastoma prevalently occurs in the mandibular molar and the ramus areas. Recurrence frequently appears after inadequate treatment. They are usually benign in growth pattern but frequently invade locally and occasionally metastasize. In the present study, a case of unusually large plexiform ameloblastoma was presented with its clinical, radiological, histological features and treatment modalities, and this is the addition of one more case in the literature.
Ewing's sarcoma is a malignant, small, round cell neoplasm that normally affects the long bones of the limbs or the pelvis. It is a relatively frequent malignant bone tumor in children. The occurrence of the primary tumor in the facial region is approximately 2%, with most of the cases affecting the mandible. Primary zygoma involvement is rare and as per the available literature only three cases have been reported.A case of Ewing's sarcoma that originated in the zygoma of a 15-year-old girl in reported. Bearing in mind its neuroectodermal origin, immunohistochemical studies are essential to distinguish Ewing's sarcoma from other small round cell tumors.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
