What is the most common malignant tumor of the parotid gland?
Mucoepidermoid carcinoma Mucoepidermoid carcinomas are the most common type of salivary gland cancer. Most start in the parotid glands. They develop less often in the submandibular glands or in minor salivary glands inside the mouth. These cancers are usually low grade, but they can also be intermediate or high grade.
What are salivary acinar cells?
Saliva is produced in and secreted from salivary glands. The basic secretory units of salivary glands are clusters of cells called an acini. These cells secrete a fluid that contains water, electrolytes, mucus and enzymes, all of which flow out of the acinus into collecting ducts.
What is acinar cell carcinoma?
Acinar cell carcinoma, also known as acinic cell carcinoma, is a malignant epithelial neoplasm composed of cells with morphological resemblance to acinar cells and with evidence of exocrine enzyme production by the neoplastic cells.
How do you get acinic cell carcinoma?
Acinic cell carcinoma is more prevalent in women than in men. The exact cause of salivary gland cancers, including acinic cell carcinoma, is unknown; however, research suggests that possible causes of the disease may be previous exposure to radiation, wood dust inhalation, and a family history of salivary cancers.
Is parotid gland an acinar?
The parotid, submandibular, and sublingual glands are all compound (branched), tubulo-alveolar (acinar) glands with a merocrine (exocytotic) type of secretion. The secretory product is either serous (a protein product secreted in vesicles) or mucous (a large sulfated glycoprotein).
What causes acinar cell carcinoma?
Acinar cell carcinoma exhibit no specific site predilection and may arise in any portion of the pancreas but are somewhat slightly more common in the head. The aetiology of the acinar cell carcinoma is unknown and there are no documented precursor lesions.
What is acinic cell carcinoma of the parotid gland?
Acinic cell carcinoma (ACC) is a low-grade malignant salivary neoplasm. The parotid gland is the predominant site of origin. ACC has a tendency to recur and metastasize, rarely enough to soft tissue as well as other sites. Medical records of a 56-year-old male with a known history of acinic cell carcinoma of the left parotid gland were reviewed.
What is acinic cell carcinoma of the salivary glands?
Acinic cell carcinoma of the salivary glands: a literature review Acinic cell carcinoma (ACC) is a low-grade malignant salivary neoplasm that constitutes approximately 17% of primary salivary gland malignancies. In the head and neck region, the parotid gland is the predominant site of origin and women are usually more frequently diagnosed than men.
What is acinic cell carcinoma (ACC)?
Acinic cell carcinoma (ACC) is a low-grade malignant salivary neoplasm that constitutes approximately 17% of primary salivary gland malignancies. In the head and neck region, the parotid gland is the predominant site of origin and women are usually more frequently diagnosed than men.
What are the signs and symptoms of parotid gland cancer?
A slowly enlarging mass lesion in the tail of the parotid gland is the most frequent presentation. The diagnosis is usually confirmed with a fine needle aspiration biopsy, and surgical excision is the main treatment of this malignant neoplasm.
