The geriatric oral lesions from the present study showed a similar trend with studies based on histopathological data, but different from the studies based on clinical data. This study also shed more light on potentially malignant disorders, as well as benign and malignant tumors.
Simple bone cyst is a benign pseudo cystic cavity in the bone that is either empty or contains fluid. It is an uncommon disorder of the jaw bones as well as the other skeletal bones, particularly the long bones. The body of the mandible is the most common site of the jaw bones. Its onset occurs mainly during the first two decades of life. This article will describe the case of a SBC located in the anterior mandible of a 15 years old female patient including clinical, radiographic, histopathologic features and its treatment.
O ral verruciform xanthoma (VX) is an uncommon oral mucosal lesion that was first described by Shafer in 1971. 1 It is a benign mucosal lesion, characterized histologically by papillary or verrucous proliferation of squamous epithelium with the presence of numerous foam cells or xanthoma cells filling the lamina propria papillae. It occurs most commonly between the ages of 30 and 60 years old with a slightly higher incidence in males. 2,3 On clinical presentation, it mostly presents with a verrucous appearance. 2 The lesion is usually present in the intraoral regions especially on the gingival. 4 The purpose of this article is to describe a rare case diagnosed as oral VX based on clinical and histopathological findings, and present a brief review of the literature. Case Report A 37-year-old Thai female presented with an asymptomatic, slightly raised white verrucous lesion, measuring 4x8 mm. in size at the buccal attached and free gingiva of the left second lower premolar region (Figure 1). Interdental gingiva between the left second lower premolar tooth and the left first lower molar tooth was involved by the lesion. It was found during a routine oral examination and the medical history was not remarkable. The patient denied any history of smoking and alcohol consumption. The clinical impression was verrucous hyperplasia and squamous papilloma. An incisional biopsy was taken from this verrucopapillary lesion to rule out dysplasia and carcinoma.
Rattana-arpha P, DDS, FRCDT Oral Malignant Melanoma of the Maxilla: A Case Report M alignant melanoma is a neoplasm of melanocytes, which originates from neuroectodermal cells. 1,2 Approximately 1% of all melanomas occur in the oral mucosa and of these, 0.5% are responsible for all malignancies arising in the oral cavity. 3,4 OMM and other mucosal malignant melanomas are considered more aggressive than cutaneous malignant melanomas with high rates of recurrence and death. 2,5 Case Report An 84-year-old Thai male presented with an enlarged, swollen gingiva on the anterior left maxilla with mild pain lasting eight weeks from the lower occluded teeth. The patient reported that the upper left lateral incisor was fractured due to large dental caries two months earlier, followed by soft tissue arising from the upper left lateral incisor to the upper second premolar tooth. The patient's past medical history was myocardial infarction, hypertension and chronic kidney disease for 10 years. The patient had taken aspirin (81 mg/d), nifedipine (40 mg/d), metoprolol (100 mg/d) and plavix (75 mg/d). His social history included occasional social alcohol use and smoking for many years.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
