1/8. A Stafne's cavity with unusual location in the mandibular anterior area.The typical Stafne's cavity, located on the posterior portion of the mandible, is a relatively uncommon entity. However, when the defect is located in the anterior region of the mandible, it is quite rare, having thus far been described in only 36 cases in the scientific literature. Most of these defects appear in the fifth and sixth decades of life, are localized to the area of the canines and premolars, and have a predilection for males. The inferior dental canal, one of the anatomical-radiographic landmarks that aid in the diagnosis of Stafne's cavity in the posterior region, is rarely present anterior the mental foramen. For this reason, because of its more variable radiographic appearance compared to the posterior defect, its tendency to be superimposed over the apices of the teeth, and the rarity of its localisation to the anterior mandible, it is much more difficult to establish a definitive diagnosis of a Stafne's cavity in this location. It is therefore more likely that a diagnostic error can occur, especially early on. We present a new case in a 68-year-old male in which the diagnosis was serendipitous, and we review in particular the aetiology and pathogenesis, clinical aspects, and differential diagnoses for this condition.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
2/8. Unusual parotid tumors.The patient presenting with a mass lesion of the parotid gland is frequently found to have a mixed tumor of salivary tissue origin. However, less common lesions occur in the anatomical region of the parotid gland. These pathological entities deserve consideration in the differential diagnosis. This report presents nine patients with unusual lesions occurring in the parotid region. These regions include cervicofacial actinomycosis, branchial cleft cyst, parapharyngeal tumors, bony lesion of the mandible, non-parotid origin malignant tumor, and metastatic malignant tumors. Each class of lesions demonstrated is also discussed.- - - - - - - - - - ranking = 0.33333333333333keywords = mandible (Clic here for more details about this article) |
3/8. Anterior lingual mandibular salivary gland defect. Evaluation of twenty-four cases.Lingual mandibular salivary gland defects in the posterior part of the mandible are not uncommon. Analogous defects in the anterior region, however, are rare, and the four new cases presented in this report bring the total number of reported cases up to 24. The purpose of the present study was to review and analyze the clinical, radiographic, and histologic features of the previously reported cases together with those of the present study. The majority of these defects were located in the cuspid and/or premolar area and were diagnosed in men in their fifth and sixth decades of life. Almost all defects contained normal salivary gland tissue. The differential diagnosis, treatment, and pathogenesis of these defects are discussed.- - - - - - - - - - ranking = 0.33333333333333keywords = mandible (Clic here for more details about this article) |
4/8. Necrotizing sialometaplasia of the mandible.A brief review of the literature on necrotizing sialometaplasia has been presented. A patient with necrotizing sialometaplasia of the retromolar pad is reported. This is the first such lesion to be described in an oral site other than the palate. Clinical, histologic, and etiologic aspects of the lesion have veen discussed.- - - - - - - - - - ranking = 1.3333333333333keywords = mandible (Clic here for more details about this article) |
5/8. Necrotizing sialometaplasia after bronchoscopy.Since the introduction of necrotizing sialometaplasia into the literature as a distinct pathologic entity in 1975, there have been several reports containing microscopic findings consistent with the disease primarily of the hard palate, but also of the soft palate, major salivary glands, retromolar pad of the mandible, and mucous glands of the nasal cavity. Localized ischemia appears to be a common link. All reported lesions heal with or without surgical intervention. Generous incisional biopsy specimens should be taken and aggressive surgery should be avoided.- - - - - - - - - - ranking = 0.33333333333333keywords = mandible (Clic here for more details about this article) |
6/8. Anterior salivary gland inclusion in the mandible: pathological entity or anatomical variant?A case of anterior salivary gland inclusion of the mandible is reported and the literature reviewed. It is suggested that these inclusions arise in the same way as the more common examples from the angle of the mandible, by progressive resorption of the lingual cortex in response to pressure exerted by the adjacent salivary glands. It is likely that these lesions become evident on radiographs only when the resorption is marked, and they may, therefore, be more widespread than reported figures indicate. Supportive evidence for this hypothesis is provided by the observations that the lesions usually present in middle age and, on histological examination, exhibit evidence of resorption.- - - - - - - - - - ranking = 2keywords = mandible (Clic here for more details about this article) |
7/8. Glandular odontogenic cysts. diagnosis and treatment.Four cases of glandular odontogenic cyst are reported. review of these and 13 previously reported cases indicates that they present as slowly growing, painless, radiolucent swellings with a predilection for the anterior part of the mandible. An incisional biopsy is essential to establish a definitive preoperative diagnosis. The unpredictable and potentially aggressive nature of these lesions is suggested by their extensive nature, penetration of cortical bone, locally invasive potential, and high incidence of recurrence after conservative treatment. In view of this behavior we suggest en bloc excision and primary reconstruction to ensure cure and reduce the operative morbidity.- - - - - - - - - - ranking = 0.33333333333333keywords = mandible (Clic here for more details about this article) |
8/8. Central mucoepidermoid carcinoma.A case of central mucoepidermoid carcinoma of the mandible is presented along with a review of the literature. The histogenesis of this tumor and the histologic similarity of the predominantly cystic low-grade central mucoepidermoid carcinoma to the glandular odontogenic cyst are discussed.- - - - - - - - - - ranking = 0.33333333333333keywords = mandible (Clic here for more details about this article) |
