A 60-year-old male patient presents with a parotid lump and facial weakness (House Brackmann grade 6). A fine needle aspiration biopsy is arranged under ultrasound guidance. What is the likely cytology repo?
The fact that the elderly man has a facial palsy means that the disease is aggressive and invaded the facial nerve. Pleomorphic adenomas are benign lesions but have a propensity to become malignant (1% per year). These lesions are named carcinoma ex-pleomorphic adenoma. Wahin's tumors tend to occur bilaterally and more common in smokers. Ultrasound guided fine needle aspiration is helpful to get a possible cytological diagnosis. Core biopsy may be required if this in non-diagnostic, or excision of the gland may sometimes be the only way to confirm the diagnosis.
