1/52. Myofibroma of gingiva: report of a case with immunohistochemical and ultrastructural study.Oral myofibroma is an uncommon, benign, solitary proliferation of myofibroblastic tissue. Few cases affecting maxillofacial region have been reported. We present a case of gingival myofibroma, diagnosed on clinical, histopathological, immunohistochemical, and ultrastructural basis.- - - - - - - - - - ranking = 1keywords = fibroma (Clic here for more details about this article) |
2/52. Atypical peripheral ossifying fibroma. A case report.The typical peripheral ossifying fibroma (POF) usually occurs on the free margin of the gingiva. POF is also thought to arise from the periodontal ligament. The case presented here is unique by virtue of its etiology, size and location.- - - - - - - - - - ranking = 0.83333333333333keywords = fibroma (Clic here for more details about this article) |
3/52. Leiomyomatous hamartoma of the incisive papilla.A case of unusual hamartoma in a six-year-old otherwise healthy Brazilian girl is reported, with emphasis on histological and immunohistochemical features. A mass observed in the incisive papilla was detected whose appearance was similar to congenital epulis or fibroma. Histological findings showed interlacing fascicles of large spindle cells resembling smooth muscle cells. Immunohistochemical staining for desmin and for smooth-muscle actin was positive. The histological diagnosis was leiomyomatous hamartoma, based on clinical and microscopic observations.- - - - - - - - - - ranking = 0.16666666666667keywords = fibroma (Clic here for more details about this article) |
4/52. Excision and repair of the peripheral ossifying fibroma: a report of 3 cases.BACKGROUND: The peripheral ossifying fibroma (POF), one of the most common gingival lesions, has a recurrence rate of nearly 20%. To minimize the reappearance of this lesion, it must be completely excised. In the maxillary anterior region, total excision of a POF can result in an unsightly gingival defect. methods: Three cases are presented in which a POF was excised from the gingiva facial to a maxillary central incisor. One of these lesions had previously undergone 2 cycles of conservative excision and recurrence. In all cases, the lesions were excised down to bone. Each of the resulting gingival defects was repaired by a distinct plastic surgery procedure, including a laterally positioned flap, a subepithelial connective tissue graft, and a coronally positioned flap. RESULTS: The defects resulting from the biopsies were satisfactorily repaired. The patients were followed over postsurgical intervals of 10 to 30 months. None of the lesions recurred. CONCLUSIONS: It is customary to manage POF by aggressive excisional biopsy. Several different surgical approaches may potentially be used to repair the resultant gingival defect and minimize patient esthetic concerns.- - - - - - - - - - ranking = 0.83333333333333keywords = fibroma (Clic here for more details about this article) |
5/52. Peripheral ossifying fibroma. Report of a case and review of the literature.Peripheral ossifying fibroma, a reactive gingival disorder known under the generic term of epulis, is widely considered to originate from the cells of the periodontal ligament. A 39-year-old woman presented with a well circumscribed, hard pedunculated exophytic tumor measuring 2 cm in size, without ulceration. The lesion had developed three months before in the interdental space, between the lower left lateral incisor and canine. No radiological signs of involvement of the alveolar ridge were observed, and the clinically manifest diastema was confirmed. The histological study of the specimen after simple resection with a cold scalpel confirmed the diagnosis of peripheral ossifying fibroma. The patient posteriorly suffered three recurrences that were respectively treated via simple resection, carbon dioxide laser exeresis and finally wide resection including the periodontal ligament, periosteum and underlying bone. There have been no further recurrences following wide resection. In addition to presenting this new case of peripheral ossifying fibroma, the present study reviews the literature, comments on the predisposing factors and treatment options, and suggests the importance of this disorder in the differential diagnosis of gingival lesions.- - - - - - - - - - ranking = 1.1666666666667keywords = fibroma (Clic here for more details about this article) |
6/52. Long-term follow-up of peripheral ossifying fibroma: report of three cases.Peripheral ossifying fibroma is a non-neoplastic enlargement of the gingiva that is classified as a reactive hyperplastic inflammatory lesion. It is possible to misdiagnose peripheral ossifying fibroma as pyogenic granuloma, peripheral giant cell granuloma, or odontogenic tumors. Therefore, histopathological examination is essential for an accurate diagnosis of such lesions. Differential diagnosis is important, because peripheral ossifying fibroma has a tendency to recur. This article describes three cases of peripheral ossifying fibroma, which were followed for 4 years without any sign of recurrence. By presenting these cases, we emphasize the importance of proper excision and aggressive curettage of the adjacent tissues for prevention of recurrence.- - - - - - - - - - ranking = 1.3333333333333keywords = fibroma (Clic here for more details about this article) |
7/52. Gingival enlargement associated with a partially erupted mandibular molar.Odontogenic lesions may present as enlarged opercula and result in the delayed eruption of teeth. This case report describes the clinical and microscopic features of a peripheral odontogenic fibroma in a 13-year-old boy that involved the overlying gingiva of a partially erupted, mandibular second molar. A differential diagnosis and treatment for lesions presenting as gingival enlargements in the molar region are discussed.- - - - - - - - - - ranking = 0.16666666666667keywords = fibroma (Clic here for more details about this article) |
8/52. Solitary neurofibroma of the oral mucosa: a previously undescribed variant of neurofibroma.We report a distinct morphologic type of neurofibroma, lipomatous neurofibroma, arising in the oral mucosa, which has not been described previously in the literature. A 25-year-old female patient presented with a solitary mucosal mass on the palatal gingiva. Although the limited biopsy material was diagnosed as a spindle cell lipoma, characteristic light microscopic neurofibromatous areas, intricately admixed with mature fat, were found in the entire resection specimen. Immunohistochemically, many of the spindle cells were positive, either diffusely or focally, for common neural markers, with patchy staining for CD34 and epithelial membrane antigen. S-100 protein was also positive in adipocytes. Ultrastructural examination confirmed the diagnosis of neurofibroma and suggested an intimate relationship between neoplastic neural cells and adipocytes.- - - - - - - - - - ranking = 2keywords = fibroma (Clic here for more details about this article) |
9/52. Oral myofibromatosis: an unusual cause of gingival overgrowth.BACKGROUND: This case report describes a rare benign tumour, which presented as discrete areas of gingival hyperplasia affecting both the mandible and the maxilla. METHOD: Surgical excision of the lesions was carried out under local anaesthetic. Histopathological examination confirmed the diagnosis of oral myofibromatosis. RESULTS: The condition responded to surgical excision and appears to have limited growth potential. It affects a wide spectrum of ages and can be alarming due to rapid enlargement and ulceration, so careful diagnosis is important to avoid unnecessary aggressive treatment.- - - - - - - - - - ranking = 0.83333333333333keywords = fibroma (Clic here for more details about this article) |
