“…Most cases of parotid gland carcinoma present a hard painless mass, which can be fixed or movable, 7,9,16,17,20,25 although approximately one-third of patients present a painful mass or facial paralysis, 7,9,16,20,27 as in our cases. The skin overlying the gland can become discolored or wrinkled, 16 which we found.…”

<p class="abstract">Malignant oncocytoma is an extremely rare neoplasm of the salivary gland accounting for 0.5% of epithelial salivary gland malignancies and 0.18% of epithelial salivary gland tumors. We report a case of malignant oncocytoma of left parotid gland in a 61-year old female patient. Patient presented with a 6-year history of painless swelling in the left parotid region. Fine needle aspiration cytology of the swelling was suggestive of pleomorphic adenoma. A computed tomography scan performed did not reveal any features suggestive of malignancy. Patient underwent left superficial parotidectomy. However, histopathological examination of the specimen turned out to be malignant oncocytoma. Malignant oncocytoma of salivary glands have rare incidence and may have similar morphologic features with other neoplasms. Despite the tumor being large and malignant in this case, there was no facial palsy preoperatively. As histopathology is often diagnostic, the possibility of malignancy always must be kept in mind preoperatively even when there is no facial palsy or fine needle aspiration cytology not showing up malignancy.</p>

“…Oncocytic carcinoma is another rare neoplasm with less than 50 reported cases. It is considered a highly malignant neoplasm with tendency for local infiltrative growth and perineural invasion, frequent local metastasis in cervical lymph nodes and distant metastasis to central nervous system, bones, liver, and lungs 19 . It may pose a real challenge to the cytopathologist since oncocytic cellular change is not infrequent in salivary gland lesions, including reactive non-neoplastic changes.…”

Salivary gland tumors are relatively rare neoplasms, mostly located in the parotid gland, and few are malignant. Preoperative evaluation of salivary gland tumors includes fine needle aspiration cytology (FNAC).ObjectiveThe purpose of this study was to determine the importance of FNAC in the evaluation of rare salivary gland neoplasms.Material and MethodsFour cases of rare salivary gland tumors were included, which were preoperatively assessed by clinical investigation, computed tomography, and FNAC.ResultsThe presented cases include myoepithelial carcinoma, oncocytic carcinoma, undifferentiated lymphoepithelial carcinoma, and marginal zone lymphoma.ConclusionFNAC is a reliable diagnostic tool for common salivary gland neoplasms; however, rare tumors often represent diagnostic challenges.Clinical relevanceIn such rare tumors, the role of aspiration cytology may be limited to establishing the dignity of the lesion (benign/malignant). This knowledge enables the surgeon to choose the most appropriate therapeutic procedure. A definitive diagnosis of rare tumors (either epithelial or nonepithelial) is obtained by histological examination; cytology is limited in this regard due to overlapping features.
