Acinic cell carcinoma (ACC) is an uncommon salivary gland neoplasm that generally displays an indolent growth pattern. Most cases arise in the major glands, particularly the parotid. However, it can arise from minor salivary glands in the oral cavity and aero-digestive tract. Although ACC is generally a low-grade malignant tumor, poorly differentiated and high-grade transformed variants exhibit a propensity for late recurrence and metastasis. There are no adequate clinical trials that define the optimal approach to patients with metastatic salivary gland tumors due to its rarity...

BACKGROUND: Myoepithelial carcinoma (MEC) is a rare salivary gland tumor. Its long-term prognosis remains unknown because of the paucity of reported cases with long-term follow-up. Although some case series exist, the clinical features of MEC vary considerably depending on the site of origin. Therefore, accumulation of these rare cases is important. CASE PRESENTATION: Case 1: An 89-year-old man presented with a 10-year history of a mass originating from the right parotid gland and involving the neck...

Mucoepidermoid carcinoma (MEC) is one of the most common malignant tumors of both major and minor salivary glands. Although there are reports of parotid MEC tumors extending intracranially via the facial nerve, intracranial extension from MEC originating from minor salivary glands in the palate has not previously been reported. This report presents a case of MEC arising from the minor salivary glands of the palate and extending into the middle fossa via the foramen rotundum with perineural invasion of the maxillary division of the trigeminal nerve...

Carcinoma ex pleomorphic adenoma (CEPA) is a carcinoma that shows histologic evidence of arising in or from a benign pleomorphic adenoma. Carcinoma ex pleomorphic adenoma often occurs in parotid glands, but is extremely rarely in the tongue. A 53-year-old Japanese woman was referred to the Department of Oral and Maxillofacial Surgery, Nagasaki University Hospital, because of tumor of the right dorsum tongue. She had a history of surgery of breast cancer (invasive ductal carcinoma) and it was disseminated to the lung and bone...

Most parotid tumors grow slowly, and sometimes these patients do not request surgical treatment until the tumors become large and affect their appearance. The surgical treatment of these large tumors is usually accompanied by large skin defects after excision, and it is challenging for surgeons to close the defect primarily. This report describes the case of a 68-year-old man with a left parotid gland tumor (largest dimension, 110 mm) and the case of a 79-year-old man with a left parotid gland tumor measuring approximately 77 mm that had existed for decades...

Sjögren's syndrome (SS) is an autoimmune disorder characterized by chronic inflammation and destruction of salivary and lacrimal glands leading to dry mouth and dry eyes, respectively. Currently, the etiology of SS is unknown and the current therapies have no permanent benefit; therefore, new approaches are necessary to effectively treat this condition. Resolvins are highly potent endogenous lipid mediators that are synthesized during the resolution of inflammation to restore tissue homeostasis. Previous studies indicate that the resolvin family member, RvD1, binds to the ALX/FPR2 receptor to block inflammatory signals caused by tumor necrosis factor-alpha (TNF-α) in the salivary epithelium...
