Infarction after fine needle aspiration biopsy of pleomorphic adenoma of the parotid gland: A case report

BACKGROUND: Fine needle aspiration (FNA) is a well-established and safe method for the rapid diagnosis of pleomorphic adenoma. A few clinically important complications, including bleeding, infection and inflammatory reactions, result from FNA. In a small number of cases FNA has been followed by varying degrees of necrosis in some organs. In the literature there are a few reports associated with necrosis in a pleomorphic adenoma of the parotid gland following FNA. CASE: A 27-year-old female had a two-year history of a right parotid mass. FNA revealed pleomorphic adenoma. A histologic diagnosis of pleomorphic adenoma of the right parotid with infarction was made. CONCLUSION: Necrosis associated with infarction may cause diagnostic problems. It is not a sufficient sign of malignant transformation
