Introduction:Odontogenic tumors (OTs) are a group of heterogeneous lesions derived from epithelial or ectomesenchymal tissues or both, which are part of the tooth-forming apparatus. They range from hamartomatous or nonneoplastic tissue proliferations to malignant neoplasms with metastatic capacity. OTs are comparatively rare, comprising about 4.79% of all oral and maxillofacial biopsy specimens diagnosed. Several retrospective studies carried out in Africa, Asia, Europe and America, show that differences exist in the relative frequency of the various histologic types. Very few studies are reported among Asians, especially from the Indian subcontinent. Hence, the present study is designed to determine the frequency of the OTs and compare them with reports of various other part of the world.Study Design:A retrospective study was carried out with the ethical clearance and permission from the authority. The histopathology records from the Department of Oral Pathology and Microbiology, within the period from January 1992 to June 2012 were obtained. A total number of OTs were analyzed for age, gender, site of the tumor and histopathological type. The odontogenic keratocyst now considered as kerato cysticodontogenic tumor (KCOT) was also included in the present study.ResultsTotally, 2652 tissue specimens were received for histopathologic examination out of which 127 were OTs. All these reported cases were benign except two cases of malignancy. Among these male: female ratio of 1.04:1 with an overall mandible: maxilla ratio of 1.01:1. The most common benign odontogenic tumor was KCOT (44.9%). Ameloblastomas were the second most common benign tumors (35.43%), followed by odontome (7.08%) and adenomatoid odontogenic tumor (4.72%). Age distribution showed a peak occurrence of the odontogenic tumor in the fourth decade (31.49%).Conclusion:OTs are rare lesions in the studied population and are represented mainly by the KCOT, ameloblastoma and odontoma. Data from the reviewed cases have shown a possible geographic variation of OTs. With the introduction of the KCOT in the 2005 WHO classification, this neoplasm is now one of the most prevalent OT types.

Schwannoma is a benign tumour of Schwann cell origin. Although it commonly occurs in the head and neck region, its intraoral presentation is rare. Establishing a clinical diagnosis of schwannoma is often difficult due to its non-specific clinical features. Hence, histopathological telltale features of Antoni A and Antoni B areas are unexpected in most cases. Reported here is a case of intraoral schwannoma affecting a 17-year-old male who presented with a slow growing mass in the lower lip.

ABSTRACT:The incidence of oral cancer is rising in India. Mortality from the disease remains high and survival has not improved significantly. Both prevention and early detection within the general dental practice setting have a potential impact on overall incidence, morbidity and mortality from oral cancers. The primary dental health team has an integral role in the early detection of oral malignancy and potentially malignant lesions. However, the clinical features may sometimes be ambiguous. The aim is to present two cases of tongue ulcers with ambiguous clinical presentation. One was innocuous tongue ulceration, not responding to conservative treatment modality and found to be squamous cell carcinoma on biopsy, treated successfully at referral center; while the other was mimicking a malignancy at initial presentation, but turned out to be innocent one. Thus, emphasizing the need of thorough routine clinical examinations as an essential mean so as to improve the survival of patient.
