Abstrakt: A case of recurrent hyalinizing clear cell carcinoma (HCCC) of the parotid gland in a 46-year-old female is here introduced. The patient had undergone a left superficial parotidectomy 6 months ago in another institution for an alleged benign, circumscribed mass 2.4 cm in diameter of the left parotid gland. Histopathological examination revealed a poorly differentiated HCCC bearing a EWSR-1 translocation on FISH examination. Fine Needle Cytology (FNC) was performed on three separate soft tissue masses in the pre-masseterine area and a cytological diagnosis of recurrent, poorly differentiated, possibly aggressive variant of HCCC, was rendered. FISH performed on a destained Diff Quik stained smear demonstrated an ESWR-1 translocation, which supported the cytopathological diagnosis. The cytomorphologic features and the differential diagnosis of this aggressive variant of HCCC are briefly discussed.
