Artifact refers to an artificial structure or tissue alteration on a prepared microscopic slide—the result of an extraneous factor. It can result in alteration of normal morphologic and cytologic features that may occur as a result of the way the tissue has been handled, right from the time the biopsy, which is surgically obtained till the entire(More)
Schwannoma is a benign, encapsulated, perineural tumor that arises from the Schwann cells. Approximately 25% of the reported cases originate from the head and neck region. Of these, approximately 1-12% occurs intraorally. The intrabony lesion accounts for less than 1% of the central neoplasms. We report a rare case of intraosseous schwannoma in an(More)
Osteosarcoma (OS) is a highly malignant bone forming tumor characterized by frankly to subtly anaplastic stromal cells with evidence of direct formation of osteoid and/or primitive bone by these cells. Incidence is lower in jaws as compared to long bones (4-13%). They have different biological behaviour but same histopathology. The mean age of occurrence is(More)
Malformations of vascular nature originate as anomalies caused due to errors in vasculogenesis. These tumors are generally broadly classified into vascular tumors (hemangiomas) and vascular malformations (venous malformations, arteriovenous malformations, lymphatic malformations). These descriptive tumors and malformations have been categorized based on the(More)
OBJECTIVE The present study was conducted with the aim to evaluate the expression of p53 in Odontogenic Keratocyst (OKC) and Ameloblastoma to correlate with the aggressiveness of these lesions. MATERIAL AND METHODS Immunohistochemical (IHC) staining was performed using anti-p53 antibody in eighteen cases each of OKC and ameloblastoma. RESULTS p53(More)
Melanoma of the oral cavity is a rare malignant disease. On account of the presence at relatively obscure areas in the oral cavity, most of oral malignant melanomas are diagnosed at a late stage. Early diagnosis is essential for successful treatment and perhaps is the key factor in improving the prognosis of oral malignant melanoma. However, no large(More)
BACKGROUND When the body has been mutilated, it is common to have the extremities or head amputated from the trunk. In concern with forensic odontology, an estimate must have been made based on the correlation of osteometry along with odontometry in determining sex, race and stature. OBJECTIVE The objective of this study is to investigate and correlate(More)
Tumor angiogenesis occurs by recruitment of endothelial cell precursors or by sprouting of existing capillaries, which differ from the normal vasculature by having an altered morphology that can be exploited for diagnosis and as a prognostic indicator. Improved technologies have propelled diagnosis into a new era. These technologies have to be used with(More)
Several tumors exhibit pH gradient reversal, with acidification of extracellular pH (pHe) and alkalinization of intracellular pH (pHi). The pH gradient reversal is evident even during the preliminary stages of tumorigenesis and is crucial for survival and propagation of tumors, irrespective of their pathology, genetics and origins. Moreover, this hallmark(More)
Dentist and oral health screening may be the latest weapon in identifying persons at risk of cardiovascular disease. Oral infections, specifically periodontitis, may confer independent risks for different systemic conditions. The risk factors associated with cardiovascular diseases also suggest that the relationship between periodontal disease and diabetes(More)
