1/52. Salivary duct carcinoma in the mandible: report of a case with immunohistochemical studies.Salivary duct carcinoma is rare. We describe a 56-year-old man who developed salivary duct carcinoma in the mandible 10 years after removal of the right second and third molars. The tumour originated in the retromolar gland or the ectopic minor salivary gland in the mandible. The panoramic radiograph showed a radiolucent, poorly circumscribed area about 40 x 30 mm in size and distal to the lower right first molar. This tooth, together with all neoplastic tissue, was removed, and histopathological examination showed it to be a salivary duct carcinoma in the mandible. On immunohistochemical staining, keratin antibodies stained the ductal structure, 1A4 antibody stained myoepithelial cells, but S-100 protein and vimentin were not seen. The patient was well and with no sign with recurrence 6 years postoperatively.- - - - - - - - - - ranking = 1keywords = gland (Clic here for more details about this article) |
2/52. A case of glandular odontogenic cyst associated with ameloblastoma: correlation of diagnostic imaging with histopathological features.The glandular odontogenic cyst (GOC) is a rare odontogenic cyst. There has only been one reported case of the simultaneous presence of GOC and ameloblastoma. The radiographic features of GOC are well established but the MR findings have not been described. We report a case of GOC associated with ameloblastoma with special reference to the correlation of the diagnostic imaging with the histopathological features.- - - - - - - - - - ranking = 2.5keywords = gland (Clic here for more details about this article) |
3/52. Submasseteric abscess: report of two cases.Submasseteric abscess is a rare infection with the symptoms of cheek tenderness and marked trismus. Submasseteric abscess is located between the masseter muscle and mandibular ramus with different appearances as sepsis, infection, or tumor. Two cases of submasseteric abscess are reported along with symptoms, causes, and management techniques. Adequate drainage and antibiotic infusion are the treatment of choice. The differential diagnosis of cheek swelling and tenderness that should be considered are parotitis, parotid gland tumor, temporomasseter joint arthritis, and submasseteric abscess.- - - - - - - - - - ranking = 0.5keywords = gland (Clic here for more details about this article) |
4/52. 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 = 0.5keywords = gland (Clic here for more details about this article) |
5/52. Central (intraosseous) adenoid cystic carcinoma of the mandible: report of a case with periapical involvement.Primary intraosseous salivary gland tumors are rare, with mucopidermoid carcinoma being the most frequent histotype. The authors present a case of adenoid cystic carcinoma, located in the mandibular incisor region, associated with pain. Endodontic treatment resulted in increased pain and progressive mandibular expansion. An apicoectomy was conducted, and an intraosseous adenoid cystic carcinoma was diagnosed at histological examination. The patient was treated by wide surgical resection, and is alive and well without recurrences or distant metastases 14 yr after the original diagnosis. The case presented herein calls attention to the preoperative clinical diagnosis of periapical lesions. Radiologically, focal sclerosing osteitis, cementoblastoma, cementifying and ossifying fibroma, periapical cemental dysplasia, complex odontoma, and calcifying epithelial odontogenic tumor should be considered in the differential diagnosis. In addition the unusual occurrence of salivary gland tumors in intraosseous location stresses the importance of systematic histological examination of any tissue sample obtained after endodontic procedures.- - - - - - - - - - ranking = 1keywords = gland (Clic here for more details about this article) |
6/52. A sequential approach to radiological interpretation.A case of large glandular odontogenic cyst of the mandible is presented in which the panoramic radiograph also demonstrated a soft tissue lesion consistent with carotid aneurysm. CT confirmed the bucco-lingual extent of the mandibular lesion and the presence of a soft tissue lesion consistent with an aneurysm of the internal carotid artery. CT angiography, MR angiography and US were used to rule out a carotid artery aneurysm prior to surgery of the mandibular lesion.- - - - - - - - - - ranking = 0.5keywords = gland (Clic here for more details about this article) |
7/52. 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 = 4keywords = gland (Clic here for more details about this article) |
8/52. Ectopic salivary gland tissue in the anterior mandible: a case report.Ectopic salivary gland inclusions in the mandible are a rare phenomenon. Classically as described by Stafne they have been found in the posterior mandibular region. Cases affecting the anterior mandible are even more unusual. We report a case of ectopic salivary gland tissue in the anterior mandible. In our discussion we emphasise the need for a thorough history, examination and relevant investigations. Mandibular radiolucencies can prove a pitfall for the unwary.- - - - - - - - - - ranking = 3keywords = gland (Clic here for more details about this article) |
9/52. Langerhans' cell histiocytosis diagnosed through periodontal lesions: a case report.BACKGROUND: Langerhans' cell histiocytosis (LCH) is a rare disorder in which a neoplastic proliferation of cells similar to the Langerhans' cell of the epidermis is observed. The disease may affect different organs as solitary or multiple lesions with a complete dissemination in different organs such as the bone (jaws), lung, hypothalamus, skin and mucous membranes, lymph nodes, liver, and other tissues. Although LCH is considered a childhood or juvenile disease, the diagnosis is often made in adults, and in many cases, a juvenile form progresses into adult life. hand-Schuller-Christian disease (HSCD) is an LCH form in which the typical lesions Involve the cranial bones, the eyes, and the pituitary gland. methods: This article describes a case of a patient diagnosed, through periodontal lesions and diabetes insipidus, as having Langerhans' cell histiocytosis. CONCLUSION: As far as LCH lesions appearing in periodontal tissues, the periodontist should be involved in the detection of oral lesions.- - - - - - - - - - ranking = 0.5keywords = gland (Clic here for more details about this article) |
10/52. A large glandular odontogenic cyst of the mandible: report of case.Glandular odontogenic cyst (GOC) is generally considered uncommon, but several investigators claim there is a more frequent occurrence than previously thought. However these case reports lacked confirming data to validate their claim. On the other hand, it is possible that cases of central mucepidermoid carcinoma or later periodontal cyst might be viewed as glandular odontogenic cyst. This is a report of a case of a 70-year old male who presented with a firm swelling in the right side of his edentulous mandible. Radiographic examination revealed a multilocular radiolucent lesion in the mandible extending from the right first premolar to the left second premolar and reaching the inferior mandible. Clinical findings, the health history, and microscopic examination of excised tissue confirmed the diagnosis of GOC. The lesion was excised and post-operative healing was uneventful.- - - - - - - - - - ranking = 2.5keywords = gland (Clic here for more details about this article) |
