Chondroid neoplasm of parotid gland is extremely rare. Only a few cases of extraskeletal chondroma and one case of chondrosarcoma of parotid gland have been reported in the literature. The cytological features of parotid gland chondroma are not well documented. A 61-year female patient presented with a slow growing left preauricular mass for past 6 years. Computer tomography scan showed a well circumscribed mass in the superficial lobe of left parotid gland. Fine needle aspiration cytology (FNAC) showed uniform chondrocytes embedded in a chondroid matrix, and was diagnosed as pleomorphic adenoma. Histological examination of the excised specimen showed a benign cartilaginous tumor, consistent with chondroma. There was no epithelial or myoepithelial component on extensive search. Chondroma is an extremely rare tumor of parotid gland and can be misdiagnosed as pleomorphic adenoma on cytology examination. However, absence of epithelial and myoepithelial component can give a clue toward a pure chondroid neoplasm. This report highlights the diagnostic features of chondroma of parotid gland and its diagnostic pitfalls in FNAC.

Background: This study aims to identify a pathogenic SDHD mutation associated with hereditary head and neck paraganglioma (HNPGL) in a Chinese family and to explore its implications for genetic counseling.
Methods: The study involved a family with 15 members spanning three generations. A 31-year-old patient (II-4) was diagnosed with a left parotid gland tumor and a right carotid body tumor, while both the father and elder sister had right carotid body tumors, and the third sister had bilateral carotid body tumors.

We describe a series of five patients with bilateral parotid enlargement as a sequalae to envenomation by the common krait (Bungarus caeruleus). Fine-needle aspiration cytology of the parotid gland was performed in four cases. The cytology revealed a mild lymphocytic inflammatory response in a red blood cell mixed proteinaceous background.

Objective: To investigate the microarchitecture and crystalline composition of sialoliths and to explore their formation mechanisms.
Methods: Sixty-six sialolith samples (51 from the submandibular glands and 15 from the parotid glands) were retrospectively collected. Their diameter and quality were measured.

Stress occurs as a reaction to mental and emotional pressure, anxiety, or scarring. Chronic stress is defined as constant submission to these moments. It can affect several body systems, increase blood pressure, and weaken immunity, thereby interfering with physiological health processes.
