1/11. Multiple Stafne bone cavities: a diagnostic dilemma.Salivary gland inclusions in the mandible are relatively uncommon. If defects occur they are generally unilateral, although bilateral cases have been reported. This article describes an unusual case in which the dental panoramic tomogram revealed three radiolucent areas in the mandible. The diagnosis of the two posterior radiolucencies was confirmed as Stafne's bone cavities but a definite diagnosis for the parasymphyseal lesion remained elusive, even after surgery. However, Stafne's bone cavities are known to occur in this region and this diagnosis remains the most probable.- - - - - - - - - - ranking = 1keywords = gland (Clic here for more details about this article) |
2/11. Anterior lingual mandibular salivary gland defect (Stafne defect) presenting as a residual cyst.Lingual mandibular salivary gland inclusion (Stafne defect) is a developmental anomaly represented by a bone concavity usually containing submandibular gland tissue. The posterior mandible region, particularly at the angle and below the mandibular canal, is the common location, and the anterior mandibular variants occur rather seldom. The latter is usually observed in the premolar and cuspid region, or more rarely in the symphysis, as a round or ovoid radiolucency sometimes appearing superimposed over the teeth's apices, resembling a true cystic lesion or an odontogenic tumor. We report an additional case of anterior lingual mandibular salivary gland defect occurring in a 42-year-old white man. It presented as an asymptomatic radiolucency located on the left side of the mandible, in the region of an absent second premolar and first molar, above the alveolar canal, mimicking a residual cyst. Histopathologic examination of the "cyst" content revealed the absence of a cyst lining and the presence of normal sublingual gland tissue.- - - - - - - - - - ranking = 8keywords = gland (Clic here for more details about this article) |

4/11. Mandibular ramus-related Stafne's bone cavity.Mandibular bone depressions located on the lingual/buccal aspect of the mandibular ramus are the rarest variants of the so-called Stafne's bone cavities, or major salivary gland-related depressions, with only 17 cases reported in the literature including both clinical cases and archaeological specimens. We report the case of a 14-year-old male patient who sought clinical assistance complaining of a hard expansion on the lower left premolar-molar region. Apart from a unilocular radiolucent lesion between the lower left second premolar and first molar, a panoramic radiograph showed another radiolucent lesion located in the right mandibular ramus, at the level of the mandibular foramen. Computed tomography (CT) revealed an expansile lesion in the left mandibular body, later diagnosed as a simple bone cyst through surgical exploration. The three-dimensional CT volume rendering reconstructed image showed that the second lesion, located on the lingual aspect of the ascending ramus, was an actual cortical bone defect, which was diagnosed as a mandibular ramus-related Stafne's bone cavity. Considering the young age of the patient, the size of the defect, the recognizedly slow development of mandibular bone defects and, above all, the location of the bone defect under discussion, we believe it to have a congenital rather than a developmental origin (i.e. it was caused by a focal failure during intramembranous ossification of the mandible). If this is the case, mandibular bone depressions should not be seen exclusively as salivary gland-related bone defects.- - - - - - - - - - ranking = 2keywords = gland (Clic here for more details about this article) |
5/11. cystadenocarcinoma of salivary gland presenting as a cystic lesion in the mandible.cystadenocarcinoma is a rare salivary neoplasm. It occurs in major and minor salivary glands and usually has a good prognosis. Mandibular involvement by salivary gland tumors at presentation is exceptionally rare. We present the first case, to our knowledge, of salivary gland cystadenocarcinoma appearing as a cystic lesion in the mandible.- - - - - - - - - - ranking = 7keywords = gland (Clic here for more details about this article) |
6/11. Developmental lingual bone defect of the mandible. Report of a case.The case of a patient with a lingual bone defect of the mandible accompanied by spontaneous pain is described. This report presents the development of the lesion, and its disappearance 26 months after removal of the submandibular gland. pain was relieved after the operation. We regard the development of this lesion related to the pressure exerted by the submandibular gland on the corical bone.- - - - - - - - - - ranking = 2keywords = gland (Clic here for more details about this article) |
7/11. Malposed sublingual gland in the anterior mandible: a variant of Stafne's idiopathic bone cavity.This article reports a case of an asymptomatic, ill-defined radiolucency in the anterior mandible in the region of the central and lateral incisor teeth, found on routine roentgenographic examination. A labial mucoperiosteal flap was raised under local anesthesia. A portion of the lingual plate and inferior border of the anterior mandible were missing, and the space was occupied by the sublingual gland extension. The entrapped sublingual gland was removed and the histological diagnosis confirmed. The mucoperiosteal flap was sutured back in position. Healing was uneventful.- - - - - - - - - - ranking = 6keywords = gland (Clic here for more details about this article) |
8/11. 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 = 6keywords = gland (Clic here for more details about this article) |
9/11. Anterior lingual mandibular salivary gland defect--a dilemma in diagnosis.Anterior lingual mandibular salivary gland defects are very rare. These lesions present as non-definitive bony radiolucencies. There are several other radiolucent entities which present in the anterior mandible with greater frequency and this creates a diagnostic dilemma for the practitioner. The ultimate and proper treatment of non-treatment depends on a correct diagnosis of these lesions. The correctness of the diagnosis and avoidance of unnecessary traumatic procedures may be aided by more sophisticated radiographic studies, such as a CAT scan and/or magnetic resonance imaging. A case of a very unusual appearing anterior lingual mandibular salivary gland defect is presented and the diagnosis, management and recommendation for more complex radiographic studies are discussed.- - - - - - - - - - ranking = 6keywords = gland (Clic here for more details about this article) |
10/11. mucus escape reaction that involves the mandible: a case report and diagnostic imaging considerations.We present a case of mucus escape reaction in which we encountered difficulty in interpreting the images acquired by plain radiography, computed tomography, and magnetic resonance imaging. The 48-year-old male Japanese patient was referred for evaluation of a gradual swelling subjacent to the inferior border of the left mandible. At the early imaging examinations, magnetic resonance imaging provided information crucial to resolving the issue of whether the lesion consisted of a central malignant disease process or a malignant disease in the submandibular space or both of these two separate disease entities. magnetic resonance imaging demonstrated no evidence of tumorous lesion, but rather showed a fluid-containing cavity that was also confirmed by the subsequent intrasurgical inspection. On further consideration of these imaging findings, we concluded that the entity was mucus escape reaction with simultaneous occurrence of an intraconnective tissue hemorrhage adjacent to the left submandibular gland, concomitant extensive bony defect of the left mandible and lingual cortical defect, and chronic sialoadenitis of the left submandibular gland.- - - - - - - - - - ranking = 2keywords = gland (Clic here for more details about this article) |
