A 68-year-old Caucasian gentleman presented with a 6-month history of a left sided Level I/II neck swelling involving the floor of mouth. MRI revealed a large cystic lesion and histology confirmed a diagnosis of primary papillary cystadenocarcinoma of the sublingual gland. Papillary cystadenocarcinoma was first described in 1991 by the World Health Organisation [WHO], and is a rare malignant neoplasm characterised by cysts and papillary endo-cystic projections. Papillary cystadenocarcinoma arising from the sublingual glands is extremely rare and has the potential to metastasise to cervical lymph nodes...

The perturbation of thyroid iodide uptake is a well-documented side effect of the utilization of iodinated contrast media (ICM) administrated intravenously. This side effect is thought to be mediated by free iodide in ICM formulations but this hypothesis has never been formally demonstrated. The aim of the present paper is to assess the validity of this hypothesis. Methods: We used mass spectrometry analysis to quantify free-iodide contamination in ICM. Established cell lines expressing the Na/I symporter (NIS) were used to quantify the effect of ICM on iodide uptake...

Congenital ranula is rare. We report a large, symptomatic, congenital plunging ranula associated with a salivary gland cyst in the neck. To the best of our knowledge, this is the first such reported case. Even though both the cysts had their origin from the sublingual gland, only the cervical cyst had a capsular covering. Herniation of a part of the immature sublingual gland anlage through a congenital mylohyoid defect, its separation, and subsequent maturation could explain this occurrence.

Mucoepidermoid carcinoma (MEC) is the most common malignancy of the salivary glands. The clinical behaviour of MEC is largely unpredictable, ranging from indolent tumour growth to highly aggressive metastatic spread. The objective of this study was to determine the clinicopathological predictors of recurrence and survival in patients with head and neck MEC. The medical records of 64 patients who underwent surgical treatment for head and neck MEC between 1982 and 2010 were reviewed. The main outcome measures were disease-free survival (DFS) and overall survival (OS)...

BACKGROUND: Thyroid gland disorders are variably associated with Prader-Willi syndrome (PWS). Many of the clinical features in newborns with PWS are similar to those found in congenital hypothyroidism (CH). CASE PRESENTATION: We report a case of a girl with CH and PWS. At the age of 9 months CH caused by an ectopic sublingual thyroid was diagnosed, and hormone replacement therapy was started. In spite of this treatment a decrease in growth velocity, weight excess and delayed development were observed...

Among tumors of the major salivary glands, tumors in the sublingual gland are rare. Although mucoepidermoid carcinoma (MEC) represents a histological type of salivary gland tumor, it is occasionally difficult to diagnose due to its histological variation. The present study reports a case of MEC harboring a mastermind-like transcriptional coactivator 2 (MAML2) gene translocation in the sublingual gland. A 76-year-old Japanese woman with a mass in the left submandibular region was referred to Kurume University Hospital (Kurume, Japan)...

The comparative structure and expression of salivary components and vesicular transport proteins in the canine major salivary glands were investigated. Histochemical analysis revealed that the morphology of the five major salivary glands-parotid, submandibular, polystomatic sublingual, monostomatic sublingual, and zygomatic glands-was greatly diverse. Immunoblot analysis revealed that expression levels of α-amylase and antimicrobial proteins, such as lysozyme, lactoperoxidase, and lactoferrin, differed among the different glands...

Radioligand therapy (RLT) with Lu-177-labeled PSMA-ligands is a new therapy option for prostate cancer. Biodistribution in normal tissues is of interest for therapy planning. We evaluated if the biodistribution of Ga-68-PSMA-11 is influenced by tumor load. RESULTS: In patients with high tumor load, SUVmean was reduced to 61.5% in the lacrimal glands, to 56.6% in the parotid glands, to 63.7% in the submandibular glands, to 61.3% in the sublingual glands and to 55.4% in the kidneys (p < 0...

Interferon regulatory factor 6 ( IRF6) acts as a tumor suppressor and controls cell differentiation in ectodermal and craniofacial tissues by regulating expression of target genes. Haploinsufficiency of IRF6 causes Van der Woude and popliteal pterygium syndrome, 2 syndromic forms of cleft lip and palate. Around 85% of patients with Van der Woude express pits on the lower lip that continuously or intermittently drain saliva, and patients with the common cleft lip and palate have a higher prevalence of dental caries and gingivitis...

A ranula is a lesion that arises from mucin spillage from the sublingual or submandibular gland ducts, beneath the mucosa of the oral floor. A plunging or cervical ranula dissects the mylohyoid muscle and appears as a submandibular swelling. Rarely, a plunging ranula is encountered without its oral counterpart. Here, we report a rare case of a plunging ranula that occurred without its oral counterpart in a 11-year-old male patient. We have also discussed the pathogenesis and treatment options for the ranula...

Methylmercury (MeHg) is one of the most toxic mercury species, which can cause many systemic damages, but little is known about its effect in the salivary glands. This study aimed to analyze the mercury levels, oxidative stress, and proteomic profile in parotid, submandibular, and sublingual salivary glands of rats, after chronic MeHg intoxication. Two groups of twenty male Wistar rats (90 days of age) were used on the experiment. MeHg group was intoxicated by intragastric gavage with MeHg at a dose of 0.04 mg/kg/day for 60 days, while the control group received only oil...

Human whole mouth saliva (WMS) is secreted by salivary glands, namely parotid, submandibular/sublingual and other minor glands of the oral cavity. It is secreted in a systematic way, and contain informative proteins and peptides for the early detection of contagious diseases and organ-related diseases. The role of WMS as a liquid biopsy for the detection of cardiovascular diseases (CVD) through Myoglobin (MYO), Cardiac troponin I (cTnI), Creatine phosphokinase MB (CK-MB), Myeloperoxidase (MPO), brain natriuretic peptide (NT-proBNP), Exosomal miRNA, C-Reactive Protein (CRP), Matrix metalloproteinase-8 (MMP-8), MMP-9 and tissue inhibitor of MMP-8 (TIMP-1), leukotriene B4 has been well reported in last decade, that have been reviewed in the literature comprehensively below...

Ranulas pose a challenging situation, both clinically and surgically, because of their location on the floor of the mouth, an area that exhibits tightly-netted vital structures. Several treatments have been proposed, including excision with or without removal of the sublingual gland, marsupialization with or without cauterization of the roof of the lesion, drainage of the lesion, and micro-marsupialization. It has been suggested that a modified micro-marsupialization technique can establish drainage of saliva and formation of new permanent epithelized tracts along the path of sutures, thereby reducing the recurrence...
