Enamel dysplasia with odontogenic fibroma-like hamartomas: review of the literature and report of a case.

This article reports on a case presenting with a rare syndrome characterized by enamel dysplasia and multiple unerupted teeth with large solid fibrous pericoronal lesions manifesting with odontogenic fibroma-like features. Our case shows in addition to these findings an anterior open bite malocclusion and gingival overgrowths. These overgrowths exhibit the microscopic features of the multiple pericoronal odontogenic fibroma-like lesions that appear to be the hallmark of this syndrome. This unusual case brings the total number documented in the literature to 5, all of which were reported from South Africa.

Proliferative verrucous leukoplakia and field cancerization: report of a case.

Proliferative verrucous leukoplakia (PVL) is a multi-focal oral pre-malignant lesion, proliferative in nature, with a tendency to recur despite adequate therapy, and a high rate of malignant transformation. The field cancerization phenomenon may explain the characteristic behaviour of PVL. A case of PVL is presented and the field cancerization concept is discussed.

HIV/TB co-infection: literature review and report of multiple tuberculosis oral ulcers.

Human immunodeficiency virus/tuberculosis (HIV/TB) co-infected subjects demonstrate enhanced HIV replication and plasma viremia; CD4+ T-cell depletion; morbidity and mortality; and susceptibility to secondary bacterial and fungal infections compared to subjects solely infected with HIV. As the incidence of HIV/TB infection has been increasing, one would have expected to encounter oral lesions of tuberculosis more frequently. However, such oral lesions are uncommon. The lesions usually occur as ulcerations of the tongue. We report an additional case in an HIV/TB co-infected 39 year-old black male, who presented with chronic, painless, multiple oral ulcers, occurring simultaneously on the tongue, bilaterally on the palate and mucosa of the alveolar ridge. Microscopic examination confirmed the presence of chronic necrotizing granulomatous inflammation, with the identification of acid fast bacilli in the affected oral mucosal tissue. Anti-retroviral and anti-tuberculous treatment resulted in the resolution of the oral lesions. Confirmatory histopathological diagnosis following a biopsy is essential to determine the exact nature of chronic oral ulceration in an HIV individual and especially to distinguish between oral squamous cell carcimoma, lymphoma, infection (bacterial or fungal) and non-specific or aphthous type ulceration.

Histopathologic changes in metabolic bone disease.

Metabolic bone disease encompasses a heterogeneous group of disorders that influence skeletal metabolism and structure. They are generally diagnosed at an advanced stage and manifest clinically with stunted skeletal growth in children and pathologic fractures in adults. Biochemical markers for bone metabolism are equivocal and microscopic examination of labeled bone remains the gold standard for the diagnosis and accurate monitoring of the response to therapy. This article reviews the role of microscopic bone changes in the diagnosis and management of metabolic bone disease.

Cemento-ossifying fibroma: case report and review of the literature.

Although the neoplastic nature of intrabony cemento-ossifying fibromas is beyond dispute, controversy exists regarding the soft tissue counterpart. Peripheral cemento-ossifying fibroma has been referred to by a variety of terms depending on whether it is accepted as being a true odontogenic tumor or a reactive gingival overgrowth. The management of a patient with peripheral cemento-ossifying fibroma in the masticatory mucosa of the anterior region of the maxilla is presented. The differential diagnosis of reactive gingival overgrowths with and without calcification is discussed.

Central odontogenic fibroma-like tumors, hypodontia, and enamel dysplasia: review of the literature and report of a case.

A patient with multiple odontogenic fibroma-like tumors in the mandible and enamel dysplasia is presented, bringing the total number of cases reported in the literature to 3. In addition to these manifestations, this case had hypodontia. The absence of associated teeth, the size of the lesions, the lingual expansion, and the green-yellow polarization of collagen with Picrosirius stains supported the neoplastic nature of the central odontogenic fibroma-like tumors in the case presented. Laminated psammomatous deposits distinguished the tumors from the World Health Organization-type central odontogenic fibroma.
