Pleomorphic adenoma of the buccal mucosa: a rare entity

Abstract

Pleomorphic adenoma is the most common salivary gland tumor, accounting for about 60% of all the salivary gland neoplasms. It mainly arises from the parotid glands and it involves the minor salivary glands in approximately 8% of the cases, with the hard palate being the most common site of its occurrence. We herein report a very rare case of pleomorphic adenoma of the buccal mucosa in a 40-year-old female which posed as a diagnostic conundrum.

Osteolipoma: An Extremely Rare Hard Palate Tumor

“…Overall, these radiological characteristics are important in distinguishing this tumor from more aggressive fat-containing lesions such as liposarcoma [11]. The role of FNAC in assessing intraoral lesions is still debatable and has variable outcomes [14][15][16][17]. With respect to intraoral osteolipoma, there is limited utility of cytology in diagnosing it due to its hardness, however, still it can provide a clue that the lesion that we are dealing can be of osseous origin.…”

“…Ancillary tests like immunocytochemistry, cell block formation, liquid based cytology followed by histopathological examination and IHC have also broadened the utilization of FNAC for the definite diagnosis of many tumors including those arising from skin adnexa. [13][14][15][16][17][18][19][20][21][22][23][24][25] In chondroid syringoma, the fine needle aspirate is usually thick and has mucoid like consistency. A cytological criteria has also been documented for its definitive diagnosis which comprises of a prominent cellular component of epithelial and myoepithelial cells embedded in a fibrillary metachromatic chondromyxoid background.…”
