ABSTRACT
The metastasizing pleomorphic adenoma (MPA) is defined as histologically benign pleomorphic adenoma that exhibits local or distant metastases. It constitutes an extremely rare group of tumors. Most patients have a history of atleast one recurrence prior to the detection of local or distant metastasis. Although the exact pathogenesis remains elusive, hematogenous and lymphatic spread are proposed theories. Mortality in these cases can be as high as 22% thereby necessitating early diagnosis. Fine needle aspiration cytology serves as a minimally invasive and cost-effective tool in the diagnosis of this rare entity. We are presenting a case of recurrent pleomorphic adenoma metastasizing to lower cervical lymph node diagnosed on fine needle aspiration cytology.
