1/13. Submaxillary gland mucocele: presentation of a case.The term mucocele is referred to two concepts: the extravasation cysts resulting from salivary glandular duct rupture, with mucin leakage into the surrounding peri-glandular soft tissue, and the retention cysts, caused by a glandular duct obstruction and resulting in a decrease or even an absence of glandular secretion. mucocele can not be considered as a true cyst because its wall lacks an epithelial lining. These lesions are very common in the minor salivary glands (particularly in the labial glands), but are very infrequent in the major salivary glands--including the submaxillary glands. The present study describes a clinical case of a right submaxillary gland mucocele resolved by surgical treatment and reviews the differential diagnosis with other clinical entities.- - - - - - - - - - ranking = 1keywords = labial (Clic here for more details about this article) |
2/13. diagnosis of systemic sarcoidosis prompted by orofacial manifestations: a review of the literature.BACKGROUND: sarcoidosis is a multifactorial systemic inflammatory disorder of unknown origin characterized by many potential signs and symptoms, as well as by the presence of noncaseating granulomas in the organs involved. sarcoidosis also may manifest in the oral and maxillofacial region. CASE DESCRIPTION: The authors describe a patient with xerostomia, dysgeusia, oral burning, xerophthalmia and bilateral parotid enlargement. She was diagnosed as having systemic sarcoidosis on the basis of the histologic findings of a biopsy of the labial minor salivary gland, as well as subsequent diagnostic evalutons. CONCLUSION AND CLINICAL IMPLICATIONS: Enlargement of major salivary glands may be the first sign of sarcoidosis in a patient with few other symptoms or clinical findings suggestive of the disease. This case emphasizes the importance of including sarcoidosis in the differential diagnosis of bilateral parotid swelling associated with xerostomia. It also highlights the dentist's potential role in the diagnosis and dental treatment of patients with systemic sarcoidosis.- - - - - - - - - - ranking = 1keywords = labial (Clic here for more details about this article) |
3/13. Parotid duct communicating with a labial pit and ectopic salivary cyst.Labial pits are usually described as blind epidermal invaginations of lip mucosa with occasional drainage of minor salivary gland secretions. A case of an aberrant parotid duct in communication with both a unilateral, commissural labial pit and an interposed salivary cyst is presented. A 7-year-old boy who had experienced lifelong clear drainage from a congenital pit at his right oral commissure developed fever, pain, and a submucosal mass of the right cheek over a 6-week period. A preoperative sialogram through the pit demonstrated a communication between the oral commissure fistula, an intervening salivary cyst, and a proximal tract from the cyst to the parotid gland. An en bloc resection of the pit, fistula tract, and cyst was performed through a transoral approach. The dissection was medial to the buccinator muscle. There has been no recurrence of the cyst after 1 year follow-up. A description of labial pits and parotid duct anomalies is presented; however, to our knowledge, this combination of anomalies has not been previously described.- - - - - - - - - - ranking = 6keywords = labial (Clic here for more details about this article) |
4/13. 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 = 4keywords = labial (Clic here for more details about this article) |
5/13. Sicca symptom in a patient with hemochromatosis: minor salivary gland biopsy for differential diagnosis.This paper reports a case of hemochromatosis with sicca symptom. The patient was a 59-year-old female who had been received a series of intravenous iron injections and blood transfusions because of anemia owing to side-effects of a chemotherapeutic agent. She complained of dry mouth and dry eyes in addition to symptoms of hemochromatosis. The histological appearance of the labial salivary gland, with heavy deposition of iron in acinar and duct epithelial cells and absence of focal lymphoid cell infiltration, did not support a diagnosis of sjogren's syndrome but suggested functional damage of the salivary glands related to iron. The patient was given desferrioxamine, and clinical symptoms improved; re-examined labial salivary gland biopsy showed no iron deposition in any parenchymal cells after the treatment.- - - - - - - - - - ranking = 2keywords = labial (Clic here for more details about this article) |
6/13. Sicca syndrome with iron deposition in the salivary glands.A case of iron deposition in the labial accessory salivary glands associated with prominent xerostomy and xerophtalmy is reported. Suffering from a myelodysplastic syndrome with refractory anaemia, this patient received multiple transfusions over the past 7 years. A transfusional haemosiderosis gradually developed. Histopathologic examination of accessory salivary glands demonstrated haemosiderin deposition in the serous alveoli and in the epithelial cells of intercalated and interlobular ducts. A relationship between the iron deposition in the salivary glands and the development of the sicca syndrome is suggested. The literature related to iron deposition in salivary glands and sicca syndrome is reviewed.- - - - - - - - - - ranking = 1keywords = labial (Clic here for more details about this article) |
7/13. Oral amyloidosis: two unusual case presentations.Two cases of oral amyloidosis are reported. In each case there were unusual oral manifestations. In the first case the patient's only complaints were of recurrent swelling of the submandibular glands and xerostomia. The diagnosis of amyloidosis was determined from a labial salivary gland biopsy. In the second case an enlarged tongue had produced displacement of the teeth, causing malocclusion. The resulting difficulty in chewing stimulated the patient to seek advice. In each case the diagnosis was confirmed by electron microscopy, congo red staining, and serum and urine electrophoresis.- - - - - - - - - - ranking = 1keywords = labial (Clic here for more details about this article) |
8/13. cheilitis glandularis: a re-evaluation.cheilitis glandularis (CG) has been attributed to hyperplasia of labial salivary glands. We studied labial biopsy specimens of five patients with clinical CG and compared their salivary tissue with that seen in patients without CG. The labial glands from patients with CG did not differ in size, depth, or histologic appearance from those seen in the controls. They showed little or no inflammation and no hyperplasia. We also reviewed forty-eight cases of CG described in the literature. The accompanying photomicrographs nearly always depicted normal-appearing labial salivary glands. The case histories and clinical descriptions suggested that many examples of CG were manifestations of actinic cheilitis, whereas others may have been unusual presentations of atopic or factitious cheilitis. We believe CG represents an unusual reaction pattern in response to chronic irritation of the lips and is unrelated to labial salivary gland hyperplasia.- - - - - - - - - - ranking = 5keywords = labial (Clic here for more details about this article) |
9/13. 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 = labial (Clic here for more details about this article) |
10/13. Necrotizing sialometaplasia of the palate. Ulcerative or necrotizing stage of leukokeratosis nicotina palati?A typical case of the recently described tumor-suspect lesion, necrotizing sialometaplasia (NS) of the palate, in a 54-year old Caucasian male is presented. Results of complete blood- and urinanalysis including serum electrophoresis and labial salivary gland biopsy strongly pointed at a local etiologic factor. Previous statements that the disease represents a new entity are questioned. The present authors favor the idea that NS is the necrotizing (ulcerative) or terminal stage of leukokeratosis nicotina palati (nicotinic stomatitis). It is of particular importance that this lesion is not diagnosed as a malignancy, as it heals spontaneously and uneventfully.- - - - - - - - - - ranking = 1keywords = labial (Clic here for more details about this article) |
