Background: Failure in regression of the thyroglossal duct is one of the most common reasons for midline swellings in the neck. Several authors have described recurrent thyroglossal duct remnants with persisting draining sinuses. However, few have described accessory salivary glands that drain into the thyroglossal duct.
Material And Methods: In this article we report two such cases with midline salivary glands in the floor of the mouth.
Results: These two patients were subsequently successfully treated with radical tissue resection in the area between the hyoid bone and foramen cecum.
Interpretation: Preoperative fistulography or sinography was useful to demonstrate the ductal ramification of the salivary glands, and use of methylene blue during surgery proved of significant value for the result.

Transcriptomic data reveal divergent paths of chitinase evolution underlying dietary convergence in anteaters and pangolins.

Ant-eating mammals represent a textbook example of convergent evolution. Among them, anteaters and pangolins exhibit the most extreme convergent phenotypes with complete tooth loss, elongated skulls, protruding tongues, and hypertrophied salivary glands producing large amounts of saliva. However, comparative genomic analyses have shown that anteaters and pangolins differ in their chitinase acidic gene (CHIA) repertoires, which potentially degrade the chitinous exoskeletons of ingested ants and termites.

Background: Endoplasmic reticulum stress (ERS) and the unfolded protein response (UPR) are adaptive mechanisms for conditions of high protein demand, marked by an accumulation of misfolded proteins in the endoplasmic reticulum (ER). Rheumatic autoimmune diseases (RAD) are known to be associated with chronic inflammation and an ERS state. However, the activation of UPR signaling pathways is not completely understood in Sjögren's disease (SD).

Decreased saliva production due to salivary gland damage can result in difficulty speaking and swallowing, significantly reducing quality of life for head and neck cancer patients receiving radiotherapy. It is therefore imperative that treatment options are available to mitigate the effects of these debilitating side effects. D-limonene, a naturally occurring terpene, has shown protective effects on saliva production during radiotherapy treatment of mice, however the lipophilic nature of the molecule has necessitated a high oral dose to facilitate sufficient absorption.

Purpose: Ultrasound-guided fine-needle aspiration cytology (FNAC) is a widely used diagnostic procedure which facilitates the differentiation of salivary gland lesions. Although the performance of salivary gland FNAC (SG-FNAC) has improved since the introduction of the Milan System for Reporting Salivary Gland Cytopathology (MSRSGC), the range of the reported performance is still wide. Therefore, the aim of this study was to determine lesion- and sampling-related factors that influence the success of SG-FNAC.

Although pleomorphic adenomas of the salivary glands are benign tumors, they can metastasize to distant organs without evidence of malignant transformation. We describe FDG PET/CT finding in a case of metastasizing pleomorphic adenoma in the right ilium occurring 22 years after initial surgical resection of a lip pleomorphic adenoma. On FDG PET/CT, the iliac metastasis appeared as an expansile osteolytic lesion with heterogeneous activity.
