Dermoid cysts are malformations that are rarely observed in the oral cavity. Histologically, they can be further classified as epidermoid, dermoid or teratoid. We report a case in which a 25-year-old man developed an epidermoid cyst presenting as a large sublingual swelling causing speech and swallowing difficulties. The differential diagnosis for dermoid(More)
Myoepithelial-epithelial carcinoma (MEC) is a low malignancy grade neoplasia which has a prevalence of 1% to 2% among all primary tumors of the salivary gland. It has a higher incidence at 60 years of age. About 60% of the patients are females. The parotid gland is the most often reported anatomical site; nonetheless, other sites have been reported, such as(More)
The central granular cell odontogenic tumor (CGCOT) is a rare lesion that usually affects the posterior region of the mandible of young adults. We present a case of CGCOT involving the mandible of a 20-year-old white woman, emphasizing the immunohistochemical characteristics using a large panel of antibodies. The lesion was removed surgically, and after 4(More)
This is a report of a 30-year-old woman who had a herpetic corneal ulcer following radial keratotomy. Clinical applications of the results of this case reveal the following questions. (1) Can antiviral metabolites be used to prevent corneal scars, especially in the visual axis? (2) Should radial keratotomy be avoided during the vulnerable menstrual cycle(More)
UNLABELLED Melanomas are malignant lesions stemming from the disorganized proliferation of melanocytes. This condition is more common on skin, but may also be detected in mucosa, such as in the oral cavity. The aim of the present study was to report similarities and differences between oral and cutaneous melanoma. KEYWORDS Melanoma; Skin; Mouth; Diagnosis.
The aim of the present study was to assess the effectiveness of preemptive dexamethasone in surgery of the lower third molars and to compare it with other oral anti-inflammatories.

This letter aimed to describe a surgical technique for oronasal fistula closure that promotes efficient healing and minimizes recurrence. The oronasal fistula was repaired by buccal flap. The technique proved to be simple and efficient.
Metadata management systems are growing from tool-specific repositories to enterprise-wide metadata repositories. In this context, one challenge is the management of the evolving metadata whose schema or meta-model itself may evolve, e.g., dynamically-added properties, which are often hard to predict upfront at the initial meta-model design time; another(More)
