Sialolithiasis. Proposal for a new minimally invasive procedure: Piezoelectric surgery
2014
Sialolithiasis is the presence of stones in the ducts of the salivary glands. Most episodes are unique, and 60-80% are located exclusively in the main excretory duct. The main clinical manifestations are swelling and pain typically before, during or after meals that decreases if the obstruction is not complete. The highest prevalence of lithiasis is in the submandibular gland -87%-, whose secretion is more viscous, followed by the parotid gland -10%- and finally the sublingual gland -3%-. The most significant consequences are caused by the prolonged blockage of the duct by a stone, which can produce a persistent ductal dilatation with a swelling that does not subside, and could lead to the …
A review of 413 salivary gland tumours in the head and neck region.
2013
Objectives: Salivary gland tumours (SGTs) are a group of heterogeneous lesions with complex clinico-pathological characteristics and distinct biological behaviours. Previous studies have reported geographic variations in site distribution, incidence and histological types of SGTs. The aim of this study was to describe the demography of SGTs seen at a tertiary health centre and compare findings with previous studies. Study design: Data on SGTs from archives of the Department of Oral Pathology and the Department of Pathology, University College Hospital Ibadan were retrieved. Information about histological types, age, sex and location were analyzed using SPSS for Window (version 20.0; SPSS In…
Plunging Ranula in a 78- year- old Male ? a rare case report
2018
The term Ranula is a Latin word meaning frog. It refers to a bluish translucent cystic lesion in the floor of the mouth resembling the underbelly of a frog. Ranulas can be true cysts occurring due to ductal obstruction of the sublingual gland or a minor salivary gland or a pseudocyst as a result of ductal injury leading to extravasation and accumulation of saliva in the surrounding tissues. Clinically ranulas present as intraoral or plunging ranulas. The prevalence of ranula is 0.2% per 1000 patients Ranulas account for 6% of all salivary gland cysts. Ranulas are more common in children and young adults. However the plunging type occurs most commonly in the later third decade. The diagnosis…
Incidence rate of metastases in the oral cavity: a review of all metastatic lesions in the oral cavity
2021
Background Metastases in the oral cavity are rare and account for only 1 to 3% of all malignant lesions in this area. The primary location from which most metastases have been described in the oral cavity in adult patients include lungs, breasts, kidneys and colon. Material and Methods A systematic search of the literature was carried out following the PRISMA statement in PubMed database. Clinical trials and case series published in the last 10 years [2010-2020] were eligible to be selected. The headings and keywords used in the searches were “cancer” AND “oral metastases”, “incidence” AND “oral metastases”, “oral metastases” AND “jaw bone”, “oral metastases” AND “soft tissue”. Results For …
Unilateral submandibular gland aplasia with ipsilateral sublingual gland hypertrophy presenting as a neck mass
2010
The congenital absence off the major salivary glands is a very infrequent disorder, in which several glands are usually involved at the same time. Sometimes this disorder can be associated with other developmental anomalies. The unilateral aplasia of the submandibular gland is an extremely rare finding with only 14 cases reported in the literature. Clinically, this kind of patients may complain of dryness of the mouth, difficulties in chewing and swallowing, severe periodontal disease or multiple caries, but usually they follow an asymptomatic course. Salivary gland aplasia can be diagnosed with a large variety off imaging techniques, which include computer tomography (CT), magnetic resonan…
Lymphadenomatous carcinoma of the sublingual gland: report of a first case in an unusual localization.
2008
Background. Lymphadenomatous carcinoma of the salivary gland is a very rare tumor, which hitherto occurred exclusively in the parotid gland. This report describes a case of lymphadenomatous carcinoma of the sublingual gland, which is thought to be the first report of this special entity. Methods and Results. A 36-year-old man was seen with slowly growing mass on his right floor of mouth. Upon surgical removal, the mass was well encapsulated. Microscopic exami- nation revealed a biphasic appearance with islands of neoplas- tic epithelial cells presenting against a dense lymphoid stroma, while the epithelial compartment showed features of malig- nancy. During 30-months of close follow-up, the…
Sublingual gland neoplasms: clinicopathological study of 8 cases
2021
Background Sublingual gland neoplasms are very rare and the majority of them are malignant. The aim of this study was to evaluate the clinical course, treatment, and outcomes of these uncommon neoplasms based on the authors’ experience and the recent literature. Material and Methods The medical charts of 8 patients with primary epithelial sublingual gland tumors treated between 1994 and 2020 were reviewed. Results Malignant tumors comprised 75% (6/8) of cases. Adenoid cystic carcinoma was the most common (50%, 3/6) and characterized by high risk of local recurrence and lung metastasis. Pleomorphic adenoma was the only representative of benign tumors with no evidence of local recurrence in f…

Immunohistochemical expression and distribution of orexin, orphanin and leptin in the major salivary glands of some mammals
2012
Abstract: The aim of the study was to assess the involvement of apoptotic factors, cytokeratins and metalloproteinase- 9 in the histogenesis of both Epithelialized Gingival Lesions (EGL) and Periapical Lesions (PAL). 55 consecutive patients, 30 with PAL and 25 with EGL, were selected for the study after clinical and radiological examinations. The PAL patients had severe periapical lesions and tooth decay with exposure of the pulp chamber. All PAL and EGL biopsies were surgically extracted, fixed in 10% buffered formalin, and processed for routine light microscopy. Ten biopsies of each category were processed for immunohistochemistry (IHC). Serial paraffin sections were stained by IHC with a…
