Oncocytic carcinoma of the salivary glands is an extremely rare malignant neoplasm. The parotid is the most frequently involved salivary gland, but tumours in the submandibular gland and minor salivary glands have also been described. It appears that oncocytic carcinoma of an ectopic salivary gland has not been reported so far. The unique case of a 78-year-old male patient diagnosed with oncocytic adenocarcinoma of an ectopic salivary gland is reported here. The patient underwent surgery and adjuvant radiotherapy. The clinical, morphological, and immunohistochemical features of this rare entity are also described.
Keywords: carcinoma; head and neck neoplasms; immunohistochemistry; oncocytoma; salivary gland neoplasms; salivary glands.
