The salivary glands in many vertebrates including mammals are exocrine glands that produce saliva through a system of ducts. Humans have three paired major salivary glands (parotid, submandibular, and sublingual), as well as hundreds of minor salivary glands. [1] Salivary glands can be classified as serous, mucous, or seromucous (mixed).
An accessory salivary gland is ectopic salivary gland tissue with a salivary gland duct system. [3] The most common location of accessory salivary gland tissue is an extra major salivary gland in front of the parotid gland. It is typically about 3 cm or less in size, and drains into the parotid duct via a single tributary. [3]
However, the condition may arise anywhere minor salivary glands are located. [nb 1] It has also been occasionally reported to involve the major salivary glands. [2] [3] It may be present only on one side, or both sides. [1] The lesion typically is 1–4 cm in diameter. [4] Initially, the lesion is a tender, erythematous (red) swelling. Later ...
Ectopic salivary gland tissue; Stafne defect - an uncommon condition which some consider to be an anatomic variant rather than a true disease. It is thought to be created by an ectopic portion of salivary gland tissue which causes the bone of the mandible to remodel around the tissue, creating an apparent cyst like
Salivary gland tumours, or neoplasms, are tumours that form in the tissues of salivary glands. The salivary glands are classified as major or minor. The major salivary glands consist of the parotid, submandibular, and sublingual glands. The minor salivary glands consist of 800 to 1000 small mucus-secreting glands located throughout the lining ...
The inflammatory lesions in Küttner's tumor may occur on one side (unilateral) or both sides (bilateral), predominantly involving the submandibular gland, [3] but is also known to occur in other major and minor salivary glands, [4] including the parotid gland. [5] [6] Overall, salivary gland tumors are relatively rare, with approximately 2.5 ...
Sialolithiasis (also termed salivary calculi, [1] or salivary stones) [1] is a crystallopathy where a calcified mass or sialolith forms within a salivary gland, usually in the duct of the submandibular gland (also termed "Wharton's duct"). Less commonly the parotid gland or rarely the sublingual gland or a minor salivary gland may develop ...
Minor trauma to the floor of the mouth is thought to damage the delicate ducts that drain saliva from the sublingual gland into the oral cavity. [2] The lesion is a mucous extravasation cyst (mucocele) of the floor of mouth, although a ranula is often larger than other mucoceles (mainly because the overlying mucosa is thicker). [3]
