Background:Although color Doppler ultrasonography (CD-USG) is useful in the diagnosis of various diseases of the head and neck, flow signals in the malignant oral tumors are less studied. This study aimed to study the usefulness of CD-USG in mapping OSCC of buccal mucosa, tongue, and lip.Materials and Methods:This was a case–control study, conducted among 60 subjects aged 20–70 years. Group A consisted of 30 cases of OSCC of buccal mucosa, tongue, and lip, whereas Group B consisted of 30 controls. CD-USG investigation of each mass was carried out. The spectral waveform (time velocity Doppler spectrum) of flow signal was analyzed for the pulsatility index (PI), resistivity index (RI), peak systolic velocity (PSV) (m/s), and end diastolic velocity (EDV) (m/s). All patients had real-time, gray-scale sonography and CD-USG with spectral wave analysis.Results:In this study, the mean value for RI in patients with malignancy was 0.40 + 0.14, whereas for healthy subjects, it was 0.83 + 0.07. The mean value for PI in patients with malignancy was 0.86 + 0.20, whereas for healthy subjects, it was 2.61 + 0.77. In the present study, the mean PSV in malignant masses was 31.72 + 13.48, whereas for healthy subjects, it was 43.87 + 20.95, and the EDV in malignant masses was 10.33 + 5.21, whereas for healthy subjects, it was 7.07 + 3.44.Conclusions:The said Doppler indices were shown to be sensitive as well as specific for the diagnosis of malignant oral tumors. Although CD-USG cannot replace histopathological procedures, it plays a definite role as an adjunct to the clinical evaluation of OSCC cases.

Lipoma, a benign tumour of adipose tissue, is one of the most common benign neoplasms of the body. However, its occurrence in oral cavity is relatively rare. It accounts for 1 to 4% of benign neoplasms of the oral cavity, affecting predominantly buccal mucosa, floor of mouth and tongue. They have been known to grow to sufficiently large sizes causing problems in mastication and speech. The usual lesion consists of a well-circumscribed, lobulated mass of mature fat cells wherein sometimes, the covering mucosa may become ulcerated presenting difficulty in its diagnosis. Herein, we are presenting a case of intra-oral lipoma affecting right anterior buccal mucosa in a 31 year old female patient. Excisional biopsy was performed and histopathological examination revealed proliferation of mature adipocytes arranged in lobules and separated by numerous fibrous septa. After a 3 month follow-up, the patient did not reveal any signs of recurrence. The clinical and histopathological findings are discussed in detail and literature is reviewed.

of alcohol and low socioeconomic status of the affected individuals apart from poor oral hygiene, poor diet, and infections of viral origin. The most widespread form of tobacco is chewing tobacco with or without betel quid and this has been demonstrated as a major risk factor for oral cancer. [3] Exposure to such toxic agents results in alterations of genes that are important in the regulation of various cellular functions. Some of these important changes include the acquisition of immortality by the cancerous cells and the ability to invade tissue and/or metastasize to other sites, as well as acquiring the ability to
