Sialadenitis associated with Sialolith- A Case Report

Sialadenitis is the inflammation of the major salivary glands. It is an insidious inflammatory disease of the major salivary glands which may lead to the development of fibrous masses. The most frequent cause of sialadenitis is the presence of a salivary duct calculi, the sialolith. Sialolithiasis is the presence of stones in the salivary gland. It presents with pain and tenderness in the affected area. A 56-year old male patient had reported in the department with pain and swelling in the right lower back region of the jaw since 7 days. On clinical, radiographic and histopathological examination, a case of sialolith was reported in the right submandibular gland along with sialadenitis.

A Case Report on Recurrent Salivary Duct Carcinoma Treated with Casodex/Nolvadex and Traditional Korean Medicine

Objectives: This study examined the case of a patient with recurrent salivary duct carcinoma and hepatic metastasis.Methods: The patient was treated with Casodex/Nolvadex from January 25th 2021 onward with doses of bicalutamide (150 mg/day) and tamoxifen (10 mg/day) every four weeks. Simultaneously, the patient was treated with Korean medicine. The tumor size was measured using computed tomography (CT). Adverse events were evaluated according to the National Cancer Institute’s Common Terminology Criteria for Adverse Events (NCI-CTCAE), version 5.0.Results: Following the four-month treatment, the extent of the proximal portion of hepatic metastasis decreased, and discomfort and physical activity gradually improved.Conclusions: The results suggest that combined chemotherapy and Korean medicine may help to reduce tumor size and improve quality of life.

Case Report: Two Cases of Salivary Duct Carcinoma in Workers With a History of Chromate Exposure

Background: Salivary duct carcinoma (SDC), one subtype of the 22 different salivary gland cancers, is a rare malignancy. Risk factors for the development of salivary gland cancer and SDC are largely unknown, although pollution has been described as one of the risk factors. In other cancers, especially in lung cancer, the carcinogenicity of chromium VI [Cr(VI)] is well-known. Here we report on two SDC patients who were occupationally exposed to Cr(VI) and discuss a potential relation between their Cr(VI) exposure and the occurrence of SDC.Case Presentation: The work history of two SDC patients was analyzed for chemical exposures. Both patients had a history of Cr(VI) exposure, with maintenance of military equipment considered as the source for this exposure. Inhalation of Cr(VI) containing particles from the removal of old paint by mechanical abrasion was identified as a probable source of exposure for both patients, and one of these patients also applied new paint. Both patients reported not to have used any respiratory protection which may have resulted in substantial inhalation of Cr(VI)-containing chromates. Furthermore, in one patient inhalation of fumes from soldering may have resulted in relevant co-exposure.Conclusion: A causal relation between Cr(VI) exposure and SDC, a rare cancer, cannot be demonstrated on an individual basis but detection in a population-based study is also unlikely because of the extremely low prevalence. Nevertheless, the work history is considered a relevant risk factor in the onset of SDC as occupational exposures to Cr(VI) occurred in poorly ventilated working environment and without using appropriate respiratory protective equipment.
