Review
Recurrent aphthous stomatitis (RAS) is the most common clinical disease of the oral mucosa. Its prevalence in the general population varies between 5 and 25%, with its peak appearance in the second decade of life. So far, the etiopathogenesis is not clear. In genetically predisposed patients, the effect of certain triggering factors would initiate the proinflammatory cytokine cascade directed against certain regions of the oral mucosa. Ulcers are round or oval with well-defined erythematous margins and a shallow ulcerated center covered with a gray or yellowish fibrinous pseudomembrane. The ulcers may reappear at intervals of a few days and months. Given the appearance of periodic thrush in the oral mucosa, the first thing to do is to make a correct differential diagnosis, rule out associated systemic diseases and assess treatable causes before reaching the diagnosis of RAS. At present, there is no curative treatment.

Review
BACKGROUND
Epidermoid and dermoid cysts are benign developmental anomalies that can form anywhere in the body. Despite the rarity of incidence in the head and neck, they can arise at a variety of craniofacial locations. The purpose of this study was to analyze the clinical features of epidermoid and dermoid cysts arising in the craniofacial region with a literature review.
METHODS
A retrospective study was designed, and clinical features and surgical considerations were investigated from a literature review. Cases of epidermoid cysts in the scalp, temporal area, glabellar area, mouth floor, and buccal mucosa were described.
RESULTS
Dermoid cysts in more lateral regions of the scalp are rarely associated with intracranial extension. Because temporal dermoid cysts have a high rate of intracranial extension, radiological evaluation of the lesions in the temporal area is imperative. Epidermoid cysts in the glabellar area are usually superficial. Consideration of the surgical approach for an epidermoid cyst of the mouth floor is important. Because epidermoid cysts in the buccal mucosa are extremely rare, differential diagnosis was emphasized. Epidermoid cysts in the scalp, in the temporal intradiploic area, on the glabellar area in the periorbital region, in the mouth floor, and in the buccal mucosa were surgically excised considering the depth and location. Ten cases of epidermoid cysts in the buccal mucosa were retrieved from the literature review.
CONCLUSIONS
Consideration of the anatomic locations of epidermoid and dermoid cysts in the craniofacial region might help facilitate accurate diagnosis and treatment.
