Generally, the clinical findings are adequate in determining the etiology of the white lesions and do not require confirmatory biopsy. However, most traumatized gingiva of the tooth bearing area expresses as erythema, ulceration, or other reactive lesions such as pyogenic granuloma. Lee PN, Hamling J. Typically we see this finding in the grouping of "premalignant" lesions of epithelial origin. Much of the time the oral mucosa is in contact with these products for short periods of time or saliva dilutes and buffers the irritants reducing the potential for an adverse reaction.

Hyperkeratosis (thickening of the stratum corneum) occurs in two forms: orthokeratotic ( Figure 1 and Figure 2) or parakeratotic hyperkeratosis. In some patients the frictional keratoses can be extensive involving the entire cheek and extending to the lips. The patient admitted to nibbling at the thickened mucosa (see second image below), which, in turn, made it thicker and easier to feel and, therefore, encouraged further nibbling. Most cases of cinnamon stomatitis are associated with prolonged contact of the offending agent. The thickened layer of keratin that develops where the smokeless tobacco is placed varies in clinical appearance depending on frequency of use or the amount used [35]. as frictional keratosis, which occurs ble cottage cheese or curdled milk.1,2 Although culture or cytopathologic tis- under a variety of diagnostic names Scraping the plaques with a tongue sue staining conrms the diagnosis, (Table 1). 1987 Feb. 15(1):46-51.

Other mucosal sites of involvement include nasal, esophageal and anogenital. The diagnosis of oral frictional hyperkeratosis was established based on the clinical and microscopic findings. 1 Given the high-risk nature of some white patches, it is important to perform a thorough history and examination. The lesions resolve after discontinuing the suspected product. 8c) [32, 35, 36]. Scattered throughout the epithelium but most appreciated in the upper spinous layer are dyskeratotic cells. WSN is inherited as an autosomal dominant trait that presents as asymptomatic thickened soft white plaques most commonly on the buccal mucosa (Fig. biting the cheek), leading to a reaction of the mucosa in the oral cavity. Messadi DV, Younai FS, Liu HH, Guo G, Wang CY. Although there are clinical similarities to frictional keratoses the histology is distinct. b A more advanced lesion demonstrates obvious mucosal thickening and wrinkling of the mucosa with intervening furrows. a Irregular, shaggy macerated appearance of the left buccal mucosa typical for cheek biting (morsicatio mucosae).
