Major salivary gland swellings frequently lead to a differential diagnosis that are frequently linked to cystic degeneration or are totally cystic in character. Retention cysts are real cysts that infrequently affect the major salivary glands.  Only 2-5% of the swellings of the major salivary glands are non-neoplastic in nature, and 6–9% of them present as cystic lesions.  The parotid gland cysts are equally common in both men and women, and they often manifest as a single, painless swelling in the parotid region that does not involve the skin or facial nerve below. The majority of reported instances have acquired origins and are blamed on obstructive processes. They exhibit a great deal of heterogeneity in epithelial lining type.  Any area of the parotid gland can develop a cystic lesion, although the lips, buccal mucosa, and mouth floor are the most frequent locations.They are typically unilateral, which prompts a parotid tumour.
