Adenoid cystic carcinoma (ACC) is rare. One of its characteristics is a high rate of distant metastasis, and the most common site is the lungs, followed by the brain and liver. Bony metastases account for up to 1.96% of cases only, however, and metastasis from the blood to the bones of distal limbs is rare. We report a 62-year-old woman who presented with pain caused by bony metastases as the first symptom eight years after being diagnosed with submandibular ACC. Although such cases are rare, they indicate that when patients who have had cancer visit the hospital with other symptoms, clinicians should make sure to rule out metastasis...

BACKGROUND: Salivary gland carcinoma ranks the sixth in head and neck cancers while it is relatively rare in its incidence. Epidemiological studies have been based mostly on institutional data, leading to selection bias in incidence evaluation. Most population-based cancer registries have grouped cancers of the minor salivary glands with oral cancer instead of with salivary gland carcinoma as a whole, because of the international disease coding. Thus, the incidence of salivary gland carcinoma has not been well assessed...

Schwannoma-like pleomorphic adenoma is a rare variant of the common benign salivary neoplasm, pleomorphic adenoma. This entity's cytomorphology closely mimics a schwannoma, potentially making a diagnosis of cytologic preparations or of surgical specimens a challenge. To the best of our knowledge, there are only six previous reports of schwannoma-like pleomorphic adenoma with eight total cases in the English language literature prior to the addition of the two cases detailed in this report. Our report includes what we believe to be the first documented case of this entity occurring in the submandibular gland...

Zhi-Yuan Chen, Yu Zhang, Yan Tu, Wei Zhao, Mei Li
BACKGROUND: Only a few cases of carcinoma ex pleomorphic adenoma arising in the submandibular gland have ever been reported, all with a poor prognosis. The standard treatment for salivary gland carcinoma ex pleomorphic adenoma is surgical resection combined with postoperative radiotherapy, but the necessity of chemotherapy as well as the most appropriate treatment regimen for patients with distant metastasis after radiotherapy remains controversial. CASE SUMMARY: This report presents the case of a 73-year-old woman who suffered submandibular gland carcinoma ex pleomorphic adenoma...

Amelogenesis imperfecta (AI) is a disease primarily affecting amelogenesis, but other various aberrations have been reported in association with this entity. Enamel-renal syndrome (ERS) is a very rare disorder associating AI with nephrocalcinosis. It is known by various synonyms such as AI nephrocalcinosis syndrome, MacGibbon syndrome, Lubinsky syndrome and Lubinsky-MacGibbon syndrome. The purposes of this article are to describe other dental anomalies which are rarely associated with AI making the diagnosis of AI a complex disorder and also to report a rare case of MacGibbon syndrome presented with sialolith of submandibular gland duct which is the first reported case in the literature...

INTRODUCTION: Sialolithiasis is the most common pathology in the submaxillary gland. The introduction of minimally invasive techniques isolated or associated with sialoendoscopy is replacing glandular resection as a treatment. The conservation of the gland is justified by the recovery of function and a low recurrence rate. The rate of complications is lower in conservative techniques than in submandibular gland resection. PATIENTS AND METHODS: Thirty-three patients with fixed stones in the hilum of the submaxillary gland were treated by transoral sialolitectomy between July 2015 and July 2018, demographic data of the patients such as the number of stones, size, time of hospital stay, complications, pre- and postoperative lingual nerve function, and lithiasis recurrence were collected...

Submandibular gland excision was performed on two patients using trans-oral robotic surgery (TORS). Complications such as the injury of marginal mandibular branch of facial nerve, ranula in the floor of the mouth, and postoperative hemorrhage were not observed. Visible cervical scar can be avoided and esthetic outcome can be expected by using this surgical modality.

Orocutaneous fistulas in the maxillofacial region may be due to tumor resection, osteoradionecrosis, or trauma, and these defects limit the function of the patients and effect aesthetic and also psychological condition. Articulation and nutrition are also affected by these fistulas. Local flaps can be used for the reconstruction of small- and medium-sized defects with ease. Submandibular gland with its rich blood supply from the facial artery is a practical and useful choice for the reconstruction of mandibular region defects...

The distribution and nature of CXCL14-immunoreactive nerve fibers in salivary glands, especially the parotid gland was immunohistochemically investigated. Furthermore, the origin of parotid CXCL14-immunoreactive nerve fibers was determined by retrograde tracing experiments. CXCL14-immunoreactive nerve fibers were localized in the parotid, submandibular, and sublingual glands, particularly in the parotid gland. Double staining using identical sections revealed that a subpopulation of cells neuropeptide Y (NPY)-containing fibers was immunopositive for CXCL14 in the parotid gland...

This study assessed the impact of chronic unpredictable mild stress (CUMS) on the structure of mouse salivary glands and the role of musk in alleviating this impact. Forty male albino mice were distributed equally into four groups; control (untreated), CUMS (exposed to CUMS for 4 weeks), CUMS+fluoxetine (FLU) (exposed to CUMS then treated with FLU, CUMS+musk (exposed to CUMS then treated with musk). Behavioral changes and serum corticosterone levels were assessed at the end of the experiment. The submandibular and parotid glands were dissected out and processed for histopathological and immunohistochemical examination using antibodies against alpha smooth muscle actin (ASMA) and brain-derived neurotropic factor (BDNF)...

BACKGROUND: The submental flap is a pedicled island flap with excellent colour match for facial reconstruction. The flap can be raised with muscle, submandibular gland or bone and can be transposed to reach defects up to two thirds of the face. We report the primary author's experience of 25 years using the submental flap from its original description to most recent technical evolutions in both Europe and Africa. METHODS: This is a retrospective study including all patients with facial defects reconstructed using a submental flap between 1991 and 2016...

Mucoepidermoid carcinomas are common malignant salivary gland tumors. Despite recent advances in diagnosis and treatment, there has not been much improvement in outcome of these patients, necessitating identification of novel targeted therapeutic agents. Genomic profiling of mucoepidermoid carcinomas has recently revealed aberrations in BAP1 gene. Therefore, we conducted this study to identify BAP1 loss by immunohistochemistry in these tumors. Mucoepidermoid carcinoma cases were retrieved; hematoxylin-and-eosin stained sections were reviewed...

The incidence of recurrent t(6;9) translocation of the MYB proto‑oncogene to NFIB (the gene that encodes nuclear factor 1 B‑type) in adenoid cystic carcinoma (ACC) tumour tissues is high. However, MYB [the gene that encodes transcriptional activator Myb (MYB)] overexpression is more common, indicating that MYB serves a key role in ACC. The current study aimed to investigate the role of MYB in salivary (S)ACC growth and metastasis. A total of 50 fresh‑frozen SACC tissues and 41 fresh‑frozen normal submandibular gland (SMG) tissues were collected to measure MYB mRNA expression, and to analyse the associations between MYB and epithelial‑mesenchymal transition (EMT) markers...

BACKGROUND: Cosmetic outcome after submandibular gland (SMG) surgery has greatly improved since the development of robotic surgery through a trans-hairline approach. However, the bulky sizes of robotic arms and the rigid design of camera and instruments in the current multiarm robotic systems increased the surgical difficulty. METHODS: Clinical and preclinical studies demonstrated the surgical configuration and procedures of robotic trans-hairline SMG resection using a flexible, single-port, and multiarm systems...

Sialorrhea is a common problem in children with disability, often negatively affecting socialization, self-esteem, and burden of care. Saliva control surgery is an available option to manage this problem, particularly when other conservative methods have failed. As little is known about the long-term impact of surgery, we followed up 62 patients who had combined bilateral submandibular duct translocation and bilateral sublingual gland excision at our pediatric hospital between 1994 and 2014. Eligible individuals were identified through a search of ICD procedure codes...

OBJECTIVES: SS is characterized by chronic inflammation of the salivary glands leading to loss of secretory function, thereby suggesting specialized pro-resolving mediators targeting inflammation to be a viable option for treating SS. Previous studies demonstrated that aspirin-triggered resolvin D1 (AT-RvD1) prevents chronic inflammation and enhances saliva secretion in a SS-like mouse model when applied before disease onset. However, this therapy cannot be used in SS patients given that diagnosis occurs post-disease onset and no reliable screening methods exist...
