Background: Histological diversity is the hallmark of pleomorphic adenoma, the most common salivary gland tumor. It may cause difficulty in cytological interpretation, due to limited and selective sampling. Case presentation: A 16-year-old female patient presented with right cheek swelling. Fine needle aspiration cytology showed squamous cells, basaloid cells, and foamy cells, along with extracellular keratin and foreign body giant cells. Characteristic metachromatic fibrillary chondromyxoid stroma, which is usually seen in pleomorphic adenoma, was not seen in the aspirate. A diagnosis of mucoepidermoid carcinoma was given on cytology. Subsequent resection revealed an encapsulated pleomorphic adenoma, with extensive squamous metaplasia and appendageal differentiation on histology. Conclusion: This case illustrates that pleomorphic adenoma with squamous metaplasia presents a potential for misinterpretation as mucoepidermoid carcinoma on cytology. We discuss the various pitfalls and the features that are helpful in distinguishing these two lesions.

Diagnostic Dilemma

Pleomorphic adenoma is a benign tumor of salivary gland. Controversy regarding the origin of various mesenchymal components exists and myoepithelial cell has a key role. Metaplastic process is triggered by minor trauma and probable etiology for this change is ischemia. It is diagnostically challenging, because diagnostic pit falls in the presence of mucinous and squamous metaplasia. Report a case of pleomorphic adenoma in the palate of a 35 years old Indian female. Biopsy revealed epithelial component with extensive squamous metaplasia and cystic degeneration. Here we discuss the role of myoepithelial cells in the pathogenesis of pleomorphic adenoma and diagnostic pit falls.

Heterotopic salivary tissue (HST) is a normal salivary tissue located outsides the major and minor salivary glands. Multiple sites of localisation of heterotopias have been described, the occurrence of HST in the neck is rare and it may have several clinical manifestation. We report the case of 72-year-old Caucasian man presenting a suspect mass on the left-sided supraclavicular region. He is known for melanoma of the right elbow, surgically treated 11 years ago. The final diagnosis of pleomorphic adenoma of HST was retained. Methods of diagnosis and management are documented. Neoplasms arising from HST are uncommon with approximately 80% of benign tumours. Warthin’s tumour is the most frequent. The localisation of these neoplasms in the lower neck is very rare and often causes a diagnostic pitfall. Histological analysis provides certainty of diagnosis, defines management and follow-up.
