1/16. cheilitis glandularis: an unusual histopathologic presentation.cheilitis glandularis (CG) is an uncommon disease that usually affects the lower lip of adults. It is characterized by enlargement and eversion of the lip in association with excretory duct dilatation. The presence of minor salivary gland hyperplasia is controversial. Three types of CG have been described in the literature; the classification is based on the common clinical and histopathologic findings (ie, simple, superficial, and deep). This report is of an unusual case of CG simplex for which the initial histopathologic diagnosis was papillary cystadenoma, a neoplastic process. The lesion was completely excised, and final microscopic review of a larger specimen revealed chronic sclerosing sialadenitis, dilated salivary secretory ducts with oncocytic change and periductal inflammation, and foci of adenomatous hyperplasia consisting of enlarged ducts exhibiting squamous epithelial metaplasia and hyperplasia with papillary architecture. The latter proliferative pattern is an unusual finding in what is otherwise clinically diagnosed as CG.- - - - - - - - - - ranking = 1keywords = lower (Clic here for more details about this article) |
2/16. 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 = 1332.4247253333keywords = mandible (Clic here for more details about this article) |
3/16. Salivary gland cysts of the oral cavity: clinical observation and surgical management.Mucoceles are common cystic lesions of the oral mucosa. Extravasation mucoceles are mainly found in the lower lip of young patients, whereas retention mucoceles are usually located in the cheek or palate of older patients. The disparate site and age incidences of extravasation and retention mucoceles suggest that these two types are not related and have different pathogenesis. Treatment modalities for mucoceles are reviewed, with special attention to the cryosurgical technique for the treatment of oral ranulas.- - - - - - - - - - ranking = 1keywords = lower (Clic here for more details about this article) |
4/16. 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 = 444.14157511111keywords = mandible (Clic here for more details about this article) |
5/16. 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 = 444.14157511111keywords = mandible (Clic here for more details about this article) |
6/16. 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 = 1776.5663004444keywords = mandible (Clic here for more details about this article) |
7/16. Necrotizing sialometaplasia affecting the minor labial glands.A case of necrotizing sialometaplasia of the lower lip, a previously unreported location for this lesion, is presented. In the past, other cases of this benign process occuring in this site may have been confused with squamous-cell or mucoepidermoid carcinoma. In order to arrive at the correct diagnosis, an ample biopsy of the lesion is mandatory.- - - - - - - - - - ranking = 1keywords = lower (Clic here for more details about this article) |
8/16. 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 = 444.14157511111keywords = mandible (Clic here for more details about this article) |
9/16. Plasma-cell dyscrasia with polyneuropathy and endocrine disorders associated with dysfunction of salivary glands.A case of plasma-cell dyscrasia with polyneuropathy and endocrine disorders that showed dysfunction of the salivary glands is reported. A 49-year-old Japanese man noticed swelling of the cervical lymph nodes and numbness in the lower extremities in May 1983. Histological examination of the enlarged cervical lymph nodes revealed many follicles penetrated by radial capillaries and proliferation of capillaries and plasma cells in the interfollicular area, forming Castleman disease-like lesions. The patient complained of a dry mouth and noticed swelling of the submandibular salivary gland in April 1984. Microscopic examination of this gland revealed an angiofollicular lymphoid lesion resembling that in the lymph nodes. He also suffered from an endocrine disturbance characterized by increased serum adrenocorticotropic hormone and impotence. This is the second reported case of plasma-cell dyscrasia with polyneuropathy and endocrine disorders that showed dysfunction of exocrine secretion. This case indicates that attention must be paid to organs of exocrine secretion as well as of endocrine secretion in this disease.- - - - - - - - - - ranking = 1keywords = lower (Clic here for more details about this article) |
10/16. cheilitis glandularis.A case of cheilitis glandularis simplex occuring in a 65-year-old white man is presented. The condition is characterized by an everted lower lip, with enlarged labial salivary glands secreting a clear, thick mucus. A history of sun exposure, dry atrophic lip, and histologic findings of epithelial dysplasia, sclerosed glands, markedly dilated ducts, chronic inflammation, and basophilic degeneration of collagen indicate a solar etiology. Surgical excision by vermilionectomy gave excellent results. A high incidence of severe epithelial dysplasia and squamous cell carcinoma associated with cheilitis glandularis indicate surgery as the treatment of choice.- - - - - - - - - - ranking = 1keywords = lower (Clic here for more details about this article) |
