“…Pleomorphic adenoma (PA), or mixed tumor, is the most common benign tumor of the salivary glands. In the head and neck area, it comprises about 3%-10% of all head and neck tumors and 50% of the major and minor salivary gland neoplasms[ 1 ]. PA of the minor salivary glands occurs in the palate (67.5%), lips (10%), cheeks (5%), tongue (2.5%), and other sites (15%); PA in a lip is relatively rare[ 1 , 2 ].…”

PA of the minor salivary glands occurs in the palate (67.5%), lips (10%), cheeks (5%), tongue (2.5%), and other sites (15%); PA in a lip is relatively rare[ 1 , 2 ]. The hard palate is the most common site of predilection (42.8%-68.8%), followed by the upper lip (15%-20%), cheek (5.5%), throat (2.5%), and retromolar region (0.7%)[ 2 ].…”

“…PA rarely affects the cheek mucosa, lip, and tongue. PA can also occur in ectopic sites such as the floor of the mouth and alveolar mucosa, Stenson’s duct, accessory parotid tissue, mandible, tonsillar tissue, lower neck, middle ear, sternoclavicular joint, thyroglossal duct, and parapharyngeal space[ 1 - 3 ]. PA presents clinically as a well-defined, asymptomatic, slow-growing, firm, nodular, rubbery lesion[ 4 - 6 ].…”

BACKGROUND Salivary gland tumors are relatively rare. Most minor salivary gland tumors are malignant with benign tumors accounting for 18% of the tumors. Pleomorphic adenoma (PA) is the most common salivary gland tumor. Lip PA is uncommon with 9.8% occurring in the upper lip. We are adding on the knowledge of the rare upper lip PA (benign mixed tumor). CASE SUMMARY We report an upper lip PA (benign mixed tumor) in a 28-year-old man. His complaint was a painless swelling on the upper lip. A painless, non-tender, well-circumscribed, slightly mobile, sessile, nodular, and rubbery (in consistency) tumor measuring 5.0 cm x 2.0 cm was noted on the left side of his upper lip. The overlying skin was not fixed and of normal color. There was no ulceration, and palpation did not elicit pain or bleeding. There was no history of trauma. Blunt dissection was used to completely excise the nodular, whitish, and encapsulated tumor. Microscopy showed a well-circumscribed and partly encapsulated biphasic lesion, with large lobules of myxo-chondroid stroma and intervening cellular nodules of basaloid cells, well-formed tubules containing eosinic secretion, and nests of myoepithelial cells. A diagnosis of PA (benign mixed tumor) was confirmed. CONCLUSION Blunt dissection is indicated to preserve the cosmesis and function of the upper lip.

“…Other sites consist of throat (2.5%), retromolar region (0.7%) and small percentage from floor of mouth and alveolar mucosa. Other ectopic presentations are along the stenson's duct, accessory parotid tissue, and parapharyngeal space (Sharma et al, 2016).…”

“…8 Thus, residual tissue may arise near the duct that has the potential to develop ectopic salivate glands as documented in multiple sites in the head and neck. 8,9 Peters et al report an isolated BMPA occurring in the middle ear and mastoid most likely arising from ectopic tissue. 2 Although plausible, reports make this differential unlikely.…”
