“…Among oncocytic major salivary gland tumors, 84% occurs in the parotid gland with male to female ratio of 1:1. [4,5] Nisha J Marla* and Poorni Bharathi T Most salivary gland tumors can be diagnosed purely on hematoxylin and eosin stained slides but clear cell tumors are an exception and generally require special stains, immunohistochemistry and even electron microscopy. Warthin's tumor without significant lymphoid cells can be misinterpreted as an Oncocytoma.…”

Primary salivary gland tumors with clear cell morphology comprise an uncommonly encountered subgroup of salivary gland neoplasm. Clear cell morphology is a known feature in both benign and malignant salivary gland tumors. Oncocytomas are uncommon tumors of the salivary gland. They have an abundance of mitochondria, which is manifested as granular eosinophilic cytoplasm by light microscopy with presence of cytoplasmic glycogen. Fixation artifact can impart cytoplasmic clearing and oncocytomas with a predominance of clear cytoplasm are labeled Clear cell oncocytomas. Accurate diagnosis of salivary gland tumors can be challenging because of the many diagnostic entities, extensive morphologic overlap, and the rarity of most tumor types. Here we report a case of Clear cell salivary oncoctyoma which was confirmed by Immunohistochemical markers by excluding morphological differential of Clear cell myoepithelioma.

“…So far only 18 cases of intraoral minor salivary gland oncocytomas have been reported in the literature. Out of the 18 cases, 6 cases are of buccal oncocytoma [ 6 , 9 ]. Thus here we report the 19th case of intraoral minor salivary gland tumor and the 7th of buccal oncocytoma.…”

“…Similarly, they account for <2% of all salivary gland neoplasms. They occur primarily in parotid glands with only a small percentage occurring in minor salivary glands [ 6 ]. Though they are bening and slow growing in nature, less than 1% have the chance of malignant transformation [ 7 ].…”

Introduction More common in major salivary glands, oncocytomas are very rare tumors. They commonly occur in the parotid gland and are painless slow growing predominantly benign tumors. The term “oncocytoma” was introduced by Jaffe to designate those tumors of the salivary glands that consist predominantly of oncocytic cells lining the salivary ducts (1) Similalry, Meza- Chavez had proposed the name “oxyphilic granular cell adenoma. (2) Oncocytomas are extremely rare, benign and slow growing in nature. Here we present a rare case of buccal oncocytoma which is to our knowledge the 19th case of intraoral minor salivary gland tumor and the 7th reported case of buccal oncocytoma. Case presentation Here we present an exceedingly rare case of buccal oncocytoma in a 14 years boy who presented to the department of ENT with right buccal swelling for 6 months. He was posed the diagnosis of buccal cyst after cytological examination supported by CT scan. He then underwent an excisional biopsy where the final diagnosis was made as Buccal Oncocytoma. Conclusions Though very rare in the picture, conditions like salivary gland oncocytomas still are reported on and off in the literature. The treatment of which is complete surgical excision.
